Micro-PWC OPERATOR’S MANUAL
1.0 Introduction
The Micro-PWC is an operator’s console for use with Micro-DCI instruments. This manual describes the
operations required to use a configured Micro-PWC. It is designed to accomplish the following objectives:
• provide instructions on how to perform operational tasks on the Micro-PWC
• provide suggestions and examples for op er a tor ac tiv itie s
• provide additional information as necessary
1.1 Intended Audience
This manual is intended for use by personnel engaged in operating Micro-DCI equipment.
1.2 Functional Description
Micro-DCI provides the capability to divide process functions among many system components to provide
operating flexibility , system reliability, reduced system costs and ease of implementation. Distribution combined with redundancy also allows system control and operating functions to be divided among system
elements to increase reliability and flexibility, and to reduce risk.
Micro-PWCs can be organized into console groups with a maximum of 10 console-type server nodes in
each group. Many types of data and configuration information are distributed automatically to all server
nodes in the same console group.
Automation of most processes requires more than control at the unit operations level. The system must
also include an inherent ability to provide process management functions such as graphical presentation of
plant process conditions as well as reporting functions. The Micro-PWC and Micro-DCI process control
instruments form the basic building bl ocks of the Micr o-DCI Distributed Control System. Th e Micro-PWC is
the human/machine interface to this system, providing the Process Operator, Process Engineer, Instrument Engineer and Maintenance personnel with global access to all process and system parameters
required by each to perform their respective tasks.
The 53PW6000 (Micro-PWC) on a Pentium-based Personal Computer hardware platform provides the
user interface in a Windows NT environment. Using interactive process graphics and hierarchical displays, the Process Operator can monitor and control all analog loop s and discrete devices interfaced to the
network, as well as sequential batch operations.
The Micro-PWC provides the Engineer with an interface through which to configure and change Graphic
and Hierarchical Displays, database I/O, Micro-DCI process contr ol functions and sequences, Log (repor t)
formats, and security features (including access levels for opera ting personnel). Most cha nges are immediate, on-line and distributed to all Micro- PWCs within the same co nsole group, requiring no com pilation time
before downloading and therefore no interruption of the process.
The Micro-PWC provides Maintenance Personnel with the capability to globally monitor the operating status of any system component on the network, and to diagnose component failures.
1.2.1 User Interface
The Micro-PWC provides the Process Operator, Engineer, and Maintenance Technician with a windowbased interface to both the process and the Micro-PWC itself. The user interface is described in detail in
Section 2.
Introduction 1
Micro-PWC OPERATOR’S MANUAL
1.2.2 Micro-PWC Management Features
The Micro-PWC contains many items which aid in managing use of the system. These include:
• User Logins
• Security Features
• Messages
• Message Routing
• System Status Display
These items are described in Section 3.
1.2.3 Hierarchical Displays
Hierarchical displays are a set of pre-configured, console group-wide, graphical representations emulating
traditional instrument displays. A three-tiered hierarchy of displays exists to provide the user with inform ation about the process. This hierarchy consists of Summary, Group, and Point displays, which are available
on all console nodes in the same console group.
A summary display provides an overview of 24 groups, arranged in six rows of four blocks. There are
1,000 summary displays available.
A group display provides an operation overview of four, six, or eight points simult aneously. All process control actions and alarm acknowledgment for po ints within a group can be performed from the group display
on a point-by-point basis.
A point display provides the most detailed information and operation functions about a single point in the
hierarchical display system. From this level the operator can perform regulatory changes. Hierarchical displays are described in Section 4.
1.2.4 Graphic Displays
Up to 10,000 group wide graphic displays can be configured on the Micro-PWC. A graphic display configured on any Micro-PWC is distributed (when saved or installed) to all Micro-PWCs on the same network.
The operator may control a process by using control pushbuttons located on graphic displays. The display
vector pushbutton allows the user to move quickly and easily to other graphics or displays of other types.
Graphic displays, control through graphics, and display vectoring are discussed in Section 7.
1.2.5 Logging
Logs are used to collect and format data for use in repo rts and spreadsheet calculations. The two types of
logs available on the Micro-PWC include event lo gs and spreadsheet logs. Logs are available group wide.
Logs are covered in Section 5.
1.2.6 Trends
Trend traces display the values of one to eight points in an analog trend format similar to tha t presented b y
a conventional strip chart recorder. Three types of trend recording are provided on the Micro-PWC, including current trending, historical trending and archival trending. Trend displays are available group wide.
Trends are covered in Section 6.
1.2.7 Process Alarms
A process alarm is generated when a pro cess variable is in a n abnormal condition . Process alarms are displayed in the top two lines of the Mini-Alarm Window, in the Alarm Review display, and are accompanied
2 Introduction
Micro-PWC OPERATOR’S MANUAL
by audible alarms. The optional annunciator display panel (ADP) and the other process alarms are covered in Section 8.
1.2.8 Events
System events occur when a problem or change-of-state is detected with the control system, as opposed
to abnormal conditions, problems, or changes-of-state associated with the process which is being monitored. System event messages are displayed in the third lin e of the Mini-Alar m Window, the Event Review
display, and the Event Historian. System events are covered in Section 9.
1.2.9 Message Review
Operator messages are used to provide the operator with information and instructions for performing
actions, and can be generated from any Micro-PWC. Operator messages are displayed in the fou rth line of
the Mini-Alarm Window and in the Message Review display, and ca n be accomp anied by an aud ible alarm.
Message review is covered in Section 10.

2.0 User Interface
2.1 Introduction
The Micro-PWC user interface provides:
• Window management
• One System Window
• One Mini-Alarm Window
• Up to four Operator Windows
The function and use of these user interface elements are explained in this section.
2.2 Micro-PWC Appearance
Visually, the graphical user interface is presented in a window based format. Multiple windows can be
opened simultaneously, allowing the user to view up to four different process displays at once.
The window format provides a three-dimensional (3D) appearance to such screen objects as buttons,
scroll bars and window frames. A pointing device, such as a mouse or track ball (refer to Section 2.3,
Input Devices), is used to select objects on the screen.
2.3 Input Devices
Operation of Micro-PWC functions is most conveniently accomplished by the use of a pointing device,
such as a mouse or track ball. Although it is possible to access all displays and all menu bar choices via
the keyboard, a pointing device is required to access the object-oriented graphical functions such as pushbuttons, toggle buttons, radio buttons and so on. (Section 2. 4, Micro -PWC Disp lay provides a detailed discussion of these items.)
✎ NOTE While it is possible to perform all process operation functions at the
PC using only a pointing device, a keyboard is required for some
configuration activities.
2.3.1 Pointing Devices
The pointer cursor (also known as the mouse cursor) is a small, mobile image on the screen, which is controlled by a pointing device such as a mouse or track ball. In this manual, the term pointer refers to the
pointer cursor, while the term mouse refers to the pointing device.

Figure 2-4. Mini-Alarm Window
The title bar identifies the window by Micro-PWC name. The nam e of the current host node is displa yed to
the right of the Micro-PWC address. If the system (i.e., Micro-PWC1) communicating with the Micro-PWC
is the primary node assigned to the Micro-PWC1 (refer to the Micro-PWC Configuration Guide), it will be
displayed in normal video. If the host node is a backup node, the host node name will be displayed in
reverse video. The title bar also contains a string which can be configured to provide further information,
such as plant name and location. The login name of the user currently logged in on the Micro-PWC
appears on the title bar, followed by the +ALARMS indicator (if more alarms exist), a Silence button, and
the Filter button. The Silence button contains a horn icon on the button face, and is visible only when audi-
ble alarms exist.
The process alarm display area has a black background, on which up to two process alarms appear. The
data contained in each line of the process alarm display area is displayed in a number of fields; the width of
each field is configurable. The fields are:
•Priority
•Area
•Time
•Date
•Tag
•Status
•Alarm tag
• Legend
The system event display area appears below the process alarm display ar ea. Event messages r eport th e
occurrence of system events (as opposed to process events) such as database loading and serve r status
(e.g., Server is Offline). One event message is displayed in this area.
The operator message display area appears below the system event display. Operator messages are sent
to all operators in an area of the plant to provide information. This feature provides the users with online

A Vector button is located immediately to the right of the Alarm Acknowledge button. This button contains the letter V. If alarm vectoring (see Section 8.4.2.1, Display Vectoring from the Alarm Review Display)
has been configured for the point named in that alarm line, the display assigned via alarm vectoring will
appear in the Operator Window which has the lowest number. If no display has been assigned via alarm
vectoring, the point display for the point in alarm will be used. If no Operator Window is open when the
Vector button is clicked, no display appears. To cause the display to appear in an Operator Window other
than the one with the lowest number, drag and drop the Vector button inside the frame of the window
where the resulting display will be contained. If the user attempts to place the display in a window other
than an Operator Window (e.g., a pop-up window), the Micro-PWC will emit a beep to indicate an error,
and no further action will be taken. If the contents of the alarm line change during the drag operation, the
alarm vectoring configuration in effect when the Vector button was selected will remain in effect until the
operation is completed.
The +ALARMS indicator is located immediately to the right of the title bar. This indicator appears when
more process alarms exist than can be shown in the alarm display area (i.e., when there are more tha n two
process alarms).
The Filter button is located to the right of the title bar, beyond the +ALARMS indicator. Clicking on th is button causes the Mini-Alarm Filtering window to appear. This window contains options which can be used to
filter process alarms by Priority and Area. If all alarms will be d isplayed the la bel on this button reads Filter;
if some alarms will not be displayed due to filtering configured for the user’s login, the label reads Filtered.
The Mini-Alarm Filtering window also provides a toggle button with which to enable or disable audible
alarms. This toggle button always present when audible alarms have been enabled for the local MicroPWC via the Device Type Assignment window described in the Micro-PWC Configuration Guide.
✎ NOTE The message filtering configured for a user’s login takes
precedence over filtering configured at any other level. If access to
a particular Message Type is filtered out at the login level, it cannot
be turned on using Filter on the Mini-Alarm or using the filter o ptions
which appear on the menu bars of the Alarm Review, Event
Review, Message Review, or Event Historian displays. All
messages which are accessible to the us er can be fur th er filter ed
using these items. If the user elects to filter the contents of a display
using a Filter option from a window menu bar or the Mini-Alarm
Window Filter, the menu bar item will change to L-FILTERED, to
indicate that filtering is local (L) to the window.
2.4.5 Operator Window
The Operator Window provides the operator interface to the process, and can display output contained in
process displays. These process displays include:
• Hierarchical displays (including Summary, Group and Point displays)
• Trend displays
•Graphics
• System Status Display (SSD)
• Process Alarm Review
14 User Interface
Micro-PWC OPERATOR’S MANUAL
• System Event Review
• Printer Review
• Event Historian
• Message Review
By default, one Operator Window automatically appears at system startup (when the Default account logs
in) or when a new user logs in, if no default CRT contexts (describ ed in Section 11.12, CRT Context Keys)
have been defined for these accounts. Under these conditions, additional Operator Windows will not automatically appear, but can be opened by the user.
It is possible to have up to four Operator Windows open simultaneously on a Micro-PWC. Section 2.4.6,
Operator Window Operations, provides further information on the default arrangement of Operator Win-
dows. A user’s login account can be configured to automatically open up to four Operator Windows each
time that user logs in. The Operator Window can be maximized, closed and resized.
Because each Operator Window operates independently, a different process display can be run in each
Operator Window. For example, while Window 1 displays a Summary Page, Window 2 could display a
Graphic, Window 3 a Trend display, and Window #4 a Process Alarm display.
2.4.5.1 Operator Window Components
The Operator Window is composed of the three main window components: a title bar, a menu bar, and a
display area.
The title bar identifies the number of the Operator Window and type of process display, if any, running in
the window. At the left end of the title bar is a small square button (which contains a horizontal bar) known
as the Window Menu button, which pro vide s ac cess to the window control functions Move, Resize, and
Lower.
The menu bar provides the user with the following items:
•Window
• Maximize/Restore button
•Select
• Redraw (depends on display type)
• Zoom (depends on display type)
•Help
The Window option on the menu bar provides access to a casca ding submenu of additional window cont rol
functions, including Page Up, Page Down, Display Back, Display Forward, Acknowledge, and Close.
The Maximize/Restore option on the menu bar is used to change the size of the Operator Window. Click
this button to enlarge a small Operator Window to fill the entire display area below the System and MiniAlarm Windows. Click this button again to return the window to its previous size.
The Select option on the menu bar provides access to a cascading submenu of process interface features,
such as Graphics, Trends, Summarie s, Point s, Group s, Quick Keys, various Review displays, and the System Status Display. If the security level of the current operator does not allow access to an option, that
option is unavailable. (It is present, but appears in a lighter shade, and is said to be “stippled out”.
The Redraw option refreshes the Operator Window display.
The Zoom option allows you to resize the contents of the Operator Window without changing the size of
the window boundaries.
User Interface 15
Micro-PWC OPERATOR’S MANUAL
The Help icon on the menu bar allows the user to access online, context sensitive system help, as well as
user generated user help.
2.4.6 Operator Window Operations
A maximum of four Operator Windows can be opened on each Micro-PWC. As windows ar e opened on the
screen, the size and location of each window and its contents are automatically adjusted to fit in the available space.
The Micro-PWC is designed to open one Operator Window automatically when the system is st arted, when
the Default Login state exists, or when a new user logs in (if no CRT Context has been assigned for that
user). The first Operator Window to be opened occupies the entire work area below the System and MiniAlarm Windows.
If a second Operator Window is opened, Operator Window #1 is resized to occupy the left half of the
screen; Operator Windows #1 and #2 are displayed side by side. The windo w content s are scaled to fit the
new size.
Operator Window #3 will occupy the lower left quadrant of the screen work area, with Operator Window #1
being resized and scaled to fit in the quadrant above it.
Operator Window #4 will occupy the lower right quadrant of the screen work area, with Operator Window
#2 being resized and scaled to fit in the quadrant above.
Although the initial size and location of each window are pre-determined, this can be modified by the operator, using the options available from the Window option on the Operator Window menu bar, or by using
the resize handles.
The windows can be restored to their original size and shape at any time by selecting Menu > Arrange
Windows discussed in Section 2.4.8, Arrange Windows Function. This function can also be accessed by
pressing the A
RRANGE WINDOWS key on the keyboard.
2.4.6.1 Open an Operator Window
To open an Operator Window manually, the System Window must first have keyboard focus. From the
System Window, select Menu > Windows > Open New Window.
Selecting this option causes an Operator Window to be opened in the display area of th e screen be low the
Mini-Alarm Window.
2.4.6.2 Page Up/Page Down Operator Window Comman ds
The Window option on the menu bar provides Page Up and Page Down functions. These functions are
used to move through other pages of the display currently o n view in the display area, such as p ages of an
Alarm Review display. Page Down moves the user from a display with a lower page number to a display
with a higher page number; e.g., from Alarm Review page 1 to Ala rm Review page 2. Page Up reverses
the process.
Page Up and Page Down can also be used to move through displays of the same type, such as the 1,000
Summary displays.
The same functionality is provided by the P
AGE UP and PAGE DOWN keys on the keyboard.
2.4.6.3 Display Back/Display Forw ard
The Window option on the menu bar provides Display Back and Display Forward functions. These functions are used to move backward and forward between the last 10 displays which have appeared in the
window, regardless of the display type. For example, a user might view a Group display, then a Point dis-
16 User Interface
Micro-PWC OPERATOR’S MANUAL
play , followed by a T rend display. To return to the Point display , the user need only select the Display Back
function. This saves time and keystrokes by removing the need to call up the display via the Select button
and resulting pop-up windows.
2.4.6.4 Acknowledge
Click the Acknowledge option to acknowlegde all alarms associated with the page on display . This option is
functional only on Point and Group displays, Alarm and Event Review displays, and Graphic displays.
2.4.6.5 Close
To close an Operator Window, position the pointer on the Window option on the menu bar of the window.
Select Close from the resulting cascade menu. A window will prompt:
Close Window?
Click Yes or No. No other action can be taken until a selection is made. This guards against accidenta l closure of an Operator Window. Any remaining windows will be resized as described in Section 2.4.6, Opera-
tor Window Operations.
2.4.6.6 Resize an Operator Window
An Operator Window can be stretched or shrunk by using the Resize menu item (available from the Window Menu button at the left side of the title bar), or by using the resize hand les located on the frame of the
Operator Window. Window size can be changed vertically, horizontally or diagonally. The display which
appears in the window is automatically adjusted to the new window size.
To resize an Operator Window using the Resize menu item, select Window > Resize. Selection can be
made using the mouse or by pressing the letter R on the keyboard.
The Operator Window can also be resized using the resize handle segments on the window frame.

Micro-PWC OPERATOR’S MANUAL
3.0 Micro-PWC Features
3.1 Introduction
The Micro-PWC console contains features which aid in the use and management of the system. These
features include activities such as:
• Logging in
• Logging out
• Changing passwords
• Opening and arranging windows
• Accessing utilities
• Accessing the System Status Display
• Printing Logs and CRT screen contents
This chapter provides basic information required to get started using the system, then moves on to briefly
discuss various system features. Note that this manual does not attempt to describe configuration operations; refer to the Micro-PWC Configuration Guide for details on configuration.
Many of these system features are accessed using the menus availab le via the System Window Menu button. (The System Window is described in Section 2.4.1, System Window.)
3.2 Getting Started
One of two states can exist on a Micro-PWC that is running:
•the System Default state (no user logged in)
•the User Logged In state
3.2.1 System Default State
The System Default state occurs after a Micro-PWC initial start up, after a user has logged out of a MicroPWC, or when a Micro-PWC is restarted. In the System Default st ate:
• security access level, Quick Keys, and CRT Context Keys are those defined in the Default
user login setup
• the user name in the title bar of the Mini-Alarm Window is Default
• the displays contained in the Operator Windows are those de fined in the initial login displays of
the Default login setup. If no initial login displays are defined for the default login, a single
Operator Window is opened, which contains the System Status Display.
When the System Default state exists, the system responds as th ough a user named Default is logged in
on the system. Depending on the security level assigned to this Default user, various activities can be performed on the system, such as opening Operator Windows, viewing displays, or printing the contents of
the CRT.
If the capuser account (with default permissions set) is logged in, a full shutdown of the Micro-PWC is not
permitted. This is because capuser is the default operator account and full shutdown privileges are withheld. If necessary a user with administrative privileges can perform full system shutdown by selecting:
Micro-PWC Maintenance > Basic > Full System Shutdown.
Micro-PWC Features 21
Micro-PWC OPERATOR’S MANUAL
3.2.2 Logging In
The User Logged In state exists when a user (other than Default) has logged in. Users can be logged in
manually or automatically.
When the Micro-PWC software is started, the login name of the current Windows user is compared to the
user login names found in the Micro-PWC configuration. If a match is found, that user will automatically be
logged into the Micro-PWC, with all of the permissions and CRT contexts configured for that Micro-PWC
user.
To log in manually, select Menu > User. The menu displayed allows the user to log in to (or out of) the
Micro-PWC. (Note that if the optional badge reader hardware and software are in use, and Inhibit Key-
board Logins has been selected, the Login option will not appear on this menu.)
✎ NOTE A security system of access levels controls the user’s access to
areas and priorities, as well as network and server functions. When
the security system is active, the user’s access to parameters is
defined by the system default or the user’s login configuration.
When the security system is inactive, no restrictions are placed on
the user’s access abilities.
Select Log In from the menu; the window in Figure 3-1 appears. In the area next to the Log In prompt enter
the login name of the user to be logged in, using either the Micro-PWC keyboard or by clicking on the
appropriate keys on the video keyboard. The login name should be followed by clicking OK. Next, enter the
password in the same manner, again followed by clicking OK.
Figure 3-1. User Login Window
If an incorrect login name or password is entered during a login attempt, a System Event message will be
generated. This message will appear in the System Event display area of the Mini-Alarm Window. The
message will also be stored in the Event Historian (refer to Section 9.4, Event Historian). The message will
include the time and date, the node name, the name o f the user already logged in on the Micro-PWC at the
time of the unsuccessful attempt, a message regarding the invalid attempt, the name of the Micro-PWC on
which the unsuccessful login was attempted, and the name under which the invalid login was attempted.
For example:
16:42:43 12-JUL-05 PWC1 User Default Invalid Login Attempt on
Terminal PWC1 Fred.
Here, the Default user was logged in on PWC1 when the user Fred unsuccessfully attempted to login.
22 Micro-PWC Features
Micro-PWC OPERATOR’S MANUAL
If the attempt is unsuccessful, a pop-up dialog will prompt:
!Login failure.
Try again?
Click OK to close the window and return to the Micro-PWC login window.
✎ NOTE It is possible to configure a user login account which is restricted
from using specified systems. If login on a Micro-PWC is denied,
the user account may be restricted from using it. Ask your system
administrator for details on Micro-PWC availability from that login
account.
The initial displays assigned in the user’s login configuration are placed on the CRT assigned to the keyboard used for the login operation. The Quick Keys (see Section 11.11, Quick Keys) and CRT Context
Keys (see Section 1 1.12, CRT Context Keys) assigned in the user’s login configuration ar e available to the
user. The user’s name is displayed in the title bar of the Mini-Alarm Window.
A user can log in on a terminal which already has an active login on it. This action causes the previous
user to be logged out. If the new user has defined a n initial CR T context (i .e., CR T Login Context Key), the
CRT will display this new environment. If no initial CRT Context has been defined, the displays on the CRT
remain unchanged.
✎ NOTE If security is activated on the system, and a user’s login account is
configured to filter out (exclude) messages from one or more
process areas, then that login account cannot be used to perform
operations on the process areas for which message filtering has
been applied. Questions on how message filtering is configured on
the system, and specifically for this account, should be directed to
the system administrator . Co nfigu rat io n of these items is discusse d
in the Micro-PWC Configuration Guide.
3.2.3 Logging Out
When a user logs out of a Micro-PWC, the following actions take place only on the CRT assigned to the
keyboard from which the user is logging out:
• The security access level, Quick Keys and CRT Context Keys change to those defined for the
Default user.
• The user name in the title bar of the Mini-Alarm Window changes to Default.
• The Login Context changes to that of the Default user , and th e login parameters will change to
those of the Default user. (In other words, when an actual user logs out, the Micro-PWC
returns to the Default login state; it is as if the Default user had logged in.)
The log out procedure is similar to that used to log in. To log out, from the System Window click Menu >
User > Log Out. The current user will be logged out.
3.2.4 Show Users Option
The Show Users option provides a list of all Micro-PWC users logged on at any one time. Click Menu >
User > Show Users to view a display containing this information. This option is described in detail in Sec-
tion 2.4.7, Show Users and Screen Contents.
Micro-PWC Features 23
Micro-PWC OPERATOR’S MANUAL
3.2.5 Changing Your Password
When a login is initially configured, the password for the login defaults to the first seven characters of the
user name entered for the login. One of a new user’s first actions should be to change this password, to
prevent unauthorized persons from using the account.
A good password is an essential component of system security. Use the following guidelines when choosing a password:
• Avoid the obvious choices, such as names, social security numbers, words that appear in a
dictionary, license plate numbers, etc.
• Make it complex; use a mixture of upper and lower case letters, as well as numbers, in the
password.
• Use all seven characters; a password that is too short is easy to guess.
While the user is not prevented from using a single character or spouse’s name as a password, this is not
good practice.
To change a password, the user must:
1. Log in on the system.
2. From the System Window, select Menu > Configure > Security > Change Password. The
Change Password window (Figure 3-2) appears, which contains a text entry box labelled
Login.
TC00030A
Figure 3-2. Change Password Window
3. Enter the login name in this entry box, then press R
4. Use the same method to enter your current password for that login name. The password will
not be displayed on the screen, for security reasons.
For most users, this operation will be performed only on one’s own login name and p assword,
although it is possible for a user with a higher access level (refer to Section 3.3.1, Security, in
this section) to change the password of a user with a lower access level. Note that by being
required to enter the password as described above, the user is forced to prove possession of
the original password before it can be changed.
✎ NOTE Passwords are case sensitive.
5. Next, enter the New Password in the appropriate text entry box, followed by R
6. Enter the new password again, this time in the Verify Password text entry box, and press
R
ETURN. Because the passwords do not appear on the screen, this step is essential to make
sure that there were no typing mistakes when the new p assword was entered.
If the new password and the verification entry match, the new password is accepted. If they do not match,
a pop-up dialog appears, advising the user to try again.

• Print all or part of the contents of a screen
• Use the calculator display
• Message configuration (described in Section 3.3.2, Message Configuration)
• Message routing (described in Section 3.3.3, Message Routing)
• Print Logs on demand
Additional Micro-PWC features which aid in management of the system, and with which the user sho uld be
familiar, are:
• Security (see Section 3.3.1, Security), which determines limits of a user’s ability to access
items on the Micro-PWC.
• The System Status Display (see Section 3.4, System Status Display), which provides
information on the Data Highway and the nodes connected to it.
Micro-PWC Features 25
Micro-PWC OPERATOR’S MANUAL
3.3.1 Security
The Micro-PWC includes a security system of nine access levels which control the user’s access to:
• Micro-PWC System functions
• Process control functions
• Plant areas
Access levels are assigned to both users and to the areas and functions. You must have an access level
equal to or higher than that of the function you wish to use, in order to have access to it. Available access
levels are listed in Table 3-1.
Table 3-1. Access Levels

Operator Level 1 (Lowest access level)
Operator Level 2
Operator Level 3
Engineer Level 1
Engineer Level 2
Engineer Level 3
Supervisor Level 1
Supervisor Level 2
Supervisor Level 3 (Highest access level)
Security can be configured to be Active or Inactive on the Micro-PWC. When the security system is active,
the user’s access to these parameters is defined by the System Default or by the user’s login configuration. When the security system is inactive, no restrictions are placed on the user’s access abilities.
If you do not have access to a function, the menu item or button for that function will appear stippled out. If
you encounter difficulty in accessing a function or plan t area, see your system administrator to verify that
you have been assigned the proper access level or to have your access level changed.
3.3.2 Message Configuration
A method of communication between operators is available on the Micro-PWC, allowing text messages
known as Operator Messages to be sent from one plant Area to another. The Message Configuration feature provides this method of generating Operator Messages from a Micro-PWC.
26 Micro-PWC Features
Micro-PWC OPERATOR’S MANUAL
To create an Operator Message, select Menu > Configure > Message Configuration. The Message Configuration window (Figure 3-3) will be displayed.
TC00032A
Figure 3-3. Message Configuration Window
The window is used to configure the text, priority, and destination of the Operator Message.
3.3.2.1 Message Text
To configure the text of the message, click in the text entry box located at the top of the Message Configuration window and enter a message of up to 80 ASCII characters.
3.3.2.2 Message Priority
Each message is associated with a priority. To set the priority, click in the Priority text entry box and enter
the number of the desired priority (range of 1 to 16).
3.3.2.3 Message Destination Area
Each message can be associated with a specific plant area. The Area assignment is used to route the
message to the devices (files, printers) which have been configured to receive Operator Messages a sso ciated with that area. The message will also be sent to all Micro-PWCs where users who have access to that
area are logged in. On the Micro-PWCs, the message will be displayed in the Message line (bottom line) of
the Mini-Alarm Window. To assign the Operator Message to an Area, click the Area button. The Area
Selection window (Figure 3-4) will be displayed.
TC00033A
Figure 3-4. Area Selection Window
Micro-PWC Features 27
Micro-PWC OPERATOR’S MANUAL
The Area Selection window consists primarily of a scrollable list box which contains 255 areas. To select
the destination area for the Operator Me ssage, click on the desired Area, then click OK. The default is
Area 1. (To exit without changing the area assignment, click Cancel.)
3.3.2.4 Send the Operator Message
To send the Operator Message and exit Message Configuration, click Send. To exit without sending the
message, click Cancel.
3.3.3 Message Routing
Information on various topics is provided by the system in the form of messages. Messages are divided
into categories called Message Classes; this enables the system to distinguish between different kinds of
messages and allows efficient message sorting.
Messages within each class are further distinguished by separation into message types. Definitions of
types within a Message Class enables the Micro-PWC to quickly process and sort messages within a
class. Message Classes on the Micro-PWC include:
• Process Alarms
•System Events
• Operator Messages
Process Alarms, System Events, and Operator Messages provide information which must be immediately
available to the operator. Messages from these three classes are displayed in the Mini-Alarm Window on
the Micro-PWC screen. The remaining Message Classes reflect status changes in the system rather than
alarm conditions; messages belonging to these classes are not displayed in the Mini-Alarm Window. Logging of messages is configurable. Questions on how Message Routing is configured on your system
should be directed to your system administrator.
In addition to Message Classes, Message Routing also allows the filtering of messages base d on the following parameters:
•Priority
•Area
Message Routing enables messages of any Message Class to be separately routed to any device which
has been configured through the Printer Assignment menu se lection. Message Routing a lso defines which
Message Types in each Message Class are to be routed to any device, filtering out messages which are
not important for the specific application.
3.3.3.1 Message Color Defini t io n
By default, messages which are sent to a printer are printed in black, and messages which are sent to a file
appear as black characters on a white background.
Different colors can be configured for use when a message from a p articular class is sent to a file (or to an
optional color printer).
✎ NOTE The message color defined here is used when the message is
logged to a device (file or printer); it is not the same as Alarm
Priority color (see Section 8.3.1, Process Alarm Priorities), and will
not affect messages in the Mini-Alarm Window or Alarm Review
display.
Any questions regarding message color definition on your system should be directed to your system
administrator.
28 Micro-PWC Features
Micro-PWC OPERATOR’S MANUAL
3.3.3.2 Message Indentation Definition
Another feature which can be configured on the system is the number of spaces of indentation to be used

3.4 System Status Display
The System Status Display (SSD), shown in Figure 3-5, provides information about each node connected
to the network.
Figure 3-5. System Status Display
Each node on the network is depicted by a graphical representation known as an SSD object.
An SSD object is composed of a schematic illustration of the node above a button containing the name of
the node and information on the state of the node and its connections to the network. The appearance of
the SSD object varies, depending on the type and state of the node. Click the button to access a menu for
the node represented by the SSD object. Like the appearance of the SSD object, the entries on the menu
vary with the type of node represented.
Figure 3-6 is an example of the SSD object for a Micro-PWC. Figure 3-7 represents a Micro-PWC client,
which provides operator displays like the Micro-PWC, but does not perform network tasks, such as database and graphics storage, and communication with other operator consoles.
Figure 3-6. SSD Object for a Micro-PWC
Micro-PWC Features 31
Micro-PWC OPERATOR’S MANUAL
Figure 3-7. SSD Object for a Micro-PWC Client
The system status display is organized into rows of nodes, using following rules:
1. A row contains nodes of only one type of device (e.g., Micro-PWC).
2. The rows of device types are ordered as follows, from top to bottom:
• Micro-PWC (labeled “PWC”)
• Micro-DCI Network Interface
If no nodes of a particular device type exist, subsequent rows of other devices are moved
up in the SSD (i.e., no blank rows are created).
3. A row can contain up to eight nodes. If more than eight nodes of one type exist on the network,
they are displayed on multiple, consecutive rows.
4. Within a row, nodes are ordered left-to-right according to device number; i.e., PWC1 appears
to the left of PWC2, and so on.
If more nodes exist on the network than can be shown in the no rm a l viewin g ar ea of the S SD, scr oll ba rs
will appear at the right and bottom sides of the display. These can be used to view the portions of the SSD
which extend beyond the normal viewing area.
If the Operator Window containing the SSD is positioned so that a node’ s SSD object is near the right edge
of the screen, it may be difficult to use the menu for the node in the normal manner. To resolve this, you
can:
• Resize or move the window so that the node is not at the right edge,
- or -
• Use the bottom scroll bar to shift the content s of the window so that the node is not at the right
edge.
3.4.1 General Information for All Node Types
All SSD objects, regardless of node type, share certain features, including:
• Node name
• Network connection information
• Info menu
These features are discussed in the following paragraphs.
3.4.1.1 Node Name
The Node Name is displayed on the face of the button which is located below the node icon. The Node
Name is composed of a three character descriptor which indicates the de vice type (for exam ple , PWC) fol-

contains, at the minimum, the following two entries:
• Network Info
• Show Available Services
3.4.1.2.1 Network Info
Clicking on the Network Info item in the Info Menu will cause a Network Info window to be displayed
(Figure 3-8).
Indicates that the node is not currently on the network. The node can no
longer be accessed from the local Micro-PWC. (However, the node was
accessible at some point in time following the most recent restart of the
local Micro-PWC. If the node is still inaccessible at the time of the next
local Micro-PWC restart, it will be removed entirely from the SSD.) The
menu of the node cannot be used in this state. The node icon is
displayed in black, as well as the Node Name.
In this case, the node name is also enclosed in parentheses.
Figure 3-8. Network Info Window Example
This window contains read-only information about the node selected from the System Status Display. The
information will include the Internet (IP) address, the host name (if any), and the Ethernet address of the
node (if known).

3.4.1.2.2 Show Available Services
Selecting Info Menu > Show Available Services displays a window similar to that found in Figure 3-9.
Figure 3-9. Services Window Example
This window contains a read-only list of the services available on the node selected from the System Status Display. This information is used by Technical Support personnel during troubleshooting. If a node
function does not work as expected, check this list to find out if the service is actually available on the
node. Note that each data tr ansaction on the n etwork is preceded by a code number identifying the service
associated with the transaction. These code numbers are shown in brackets preceding each item on the
list of available services. For example:
[0001] DBA
{0003] Screen Services
[0024] Process Summary Service
[0056] Event Bit Updates
3.4.2 Information for Specific Node Types
The following paragraphs describe the information shown on SSD objects which is specific to individual
notes types.
3.4.2.1 Console-Type Notes: Micro-PWC
The SSD object for a Micro-PWC is shown in Figure 3-6. The pull-down menu available from these icons
contains only the INFO item. (See the Micro-PWC Installation and Setup Guide for a detailed discussion of
the software installation procedure for the Micro-PWC.)
3.4.2.2 Micro-DCI Communications Node
The pull-down menu on a Micro-DCI Communications Node contains an Info item and a Super32 Network
Display item. If the user has Supervisor 1 security level or greater, a Micro-DCI network configuration win-
dow can be called up by selecting the Super32 Network Display item.
3.4.2.3 The Utilities Menu

Figure 3-10. Device Status Window
The Device Status window provides information about items being printed. It also provides access to job
and printer control. The following information is provided for each device:
• Device name
• Device status
•Node
• Active backup unit name (Assign)
• Queue size
• Number of queue entries
• Size of current job
• Percent of current job printed
3.4.2.4 Printer Queue Cont rol
The column labelled Device Name contains a button for each device which has been defined via Printer
Assignment configuration (see the Micro-PWC Configuration Guide). The name of the device appears on
the face of the button. The color of the button indicates the status of the device:
• Green indicates the device is operating NORMALLY.
• Red indicates the device has FAILED.
• Yellow indicates the device has been placed in SUSPEND mode.
✎ NOTE When the button color changes to indicate the device status, the
text on the button also changes color so that it remains visible. The
text color has no other significance.
In addition to button color, the Device Status field to the right of each Device Name button provides status
indication in text form, i.e., it will display the word Normal, Failed or Suspended.
Micro-PWC Features 35
Micro-PWC OPERATOR’S MANUAL
When the Device Name button is clicked, the Printer Queue Control window (Figure 3-11) will be dis-
played.
TC00039A
Figure 3-11. Printer Queue Control Window
The first item in the Printer Queue Control window is the name of the device. Below this identifier the window is divided into two main sections. The first of these is labelled Cancel and contains two buttons:
• Current Item
• All Items
Click Current Item to terminate the job which is active in the device. Click All Items to terminate the active
job and delete all other entries from the queue for that device.
Cancelling a job removes its entry from the print queue; however, any portion of the job which has already
been loaded into buffer space (in any relevant device, such as the printer, the Micro-PWC, and so on) will
be printed. Therefore, it is not unusual for a few pages of a job to print out after the job ha s been cancele d.
The next portion of the window is labelled Control, which also contains two buttons:
• Suspend
•Normal
Click Suspend to suspend operation of the device (Suspend mode). When in Suspend mode, processing
of any jobs in the queue will be completed, but no new jobs will be accepted in the queue. Click Normal to
return to normal operation.
3.4.2.5 Printer Queue Informat io n
The Node field on the Device Status window displays the name of the node which is currently serving the
print device.
When a device is operating normally, nothing is displayed in the Assign field. When a device fails, the
Assign field will display the device name of the backup unit which is actually servicing the queue for the
failed device. Backup device assignments are configured via Printer Assignment (see the Micro-PWC Con-
figuration Guide).
The Queue Size field displays the number of bytes in all jobs in the device’s print queue, while the Queue
Entries field indicates the number of jobs in the queue. The Current Item Size indicates the size, in bytes,
of the job which is currently active. The % Printed field indicates what portion of the currently active job has
been completed.

Micro-PWC OPERATOR’S MANUAL
3.4.2.6 Console Group Information
To help control the synchronization of configuration data, Micro-PWC nodes are assigned to console
groups. Nodes within a console group synchronize configuration data only with those nodes within the
same console group. Note that console group assignment has no effect on the ability to view collected dat a
in the various databases, including the Historical, Archival, Batch, Historical Block, Archival Block and
Event Bit Databases.
If there is a reason to distribute console group-wide data to another console group (for example, you may
have a graphic or spreadsheet you wish to use in more than one console group) this information can be
distributed to other console groups via the Console Group Synchronization utility, described in Section
11.13, Console Group Synchronization.
Assignment to a console group is made during the installa tion of the Micro-PWC softwar e. The default console group number provided during the insta llation proc edure is 1. A n ode cannot be in more than on e console group. Up to 10 console nodes can exist in each group. Console groups can be assigned to numbers
from 1 to 50; this provides flexibility when assigning numbers. (While technically 50 console groups can
exist on the Network, the number of operator seats should be restricted to 50 per Network. Having more
than 50 operator seats on a Network could have a negative effect on system performance.) Console Gr oup
assignments can be revised at any time after installation, using the Micro-PWC Maintenance Utility.
The System Status Display provides information about each node connected to the network. To see how
the console nodes on the network are grouped, click on the Utilties option on the System Status Display
menu bar, then click Console Groups Display. The Console Groups Display window (Figure 3-12) will
appear.
The Console Groups Display window is divided horizontally into a section for each console group. The
group number is displayed, followed by a group of icons with node numbers, representing the console
nodes in that group. The console group which includes the local node is e nclosed within a cya n box. Micr oPWC Client nodes are console-type nodes, but are by default members of the console group of their
server. This is represented visually on the Console Groups Display, where Micro-PWC Client icons are
grouped together in boxes following their primary nod e; a black line ind ica te s the r ela tionship be tween the
primary node and its client nodes.

4.4 Process Control Functions
Control functions provide the ability to monitor individual process variables and devices, and provide the
ability to perform manual and automatic mode device control. Process information is received in reports
from function configured in a controller module. The control ability allows changing process conditions from
the Micro-PWC by initiating changes to the controller. A controller receives input from and sends output
signals to the process through termination units connected to process devices and stations.
✎ NOTE Control abilities can be limited to specific personnel by defining
password security. The security level of a user must give control
access rights before any control can be initiated.
4.4.1 Dynamic Faceplates
Dynamic faceplates for the different types of function codes can be either standard or user created. Standard control faceplates are provided. A control facepla te can be a fixed part of a display or it can be called
as a pop-up faceplate. The same control actions can be performed from a fixed faceplate as can be performed from a pop-up faceplate. This assumes that the symbol file used for the fixed faceplate is also the
46 Hierarchical Process Displays
Micro-PWC OPERATOR’S MANUAL
same one used for the pop-up faceplate, or the pop-up faceplate, if different, has all the same capabilities
as the fixed faceplate built in. When a group is opened the operator has control access to all of the faceplates within the group.
• To access control faceplates from control graphics click a control pushbutton.
• To access faceplate from a group information window click the tagname on the left side of the
window. Faceplates pro vid e access to point displays for the tags that they control.
• To access a point display click the tagname button at the top of the faceplate.
4.5 Control Faceplates
Control faceplates provide access to control function within a module. The access can be used to manually
initiate process changes and to monitor the results of both automatic and manual control operations. Automatic refers to operation being performed under controller execution. Manual refers to those actions initiated after taking a function out of automatic control. Refer to the appropriate control system manual for
detailed descriptions of the associated control faceplates.

5.0 Logs
5.1 Introduction
A log is used to collect and format data for use in reports and spreadsheet calculations. Two types of
group-wide logs are available on the Micro-PWC:
• Event Logs
• Spreadsheet Logs
Logs are distributed to all Micro-PWCs in the same console group.
Event logs are used to examine the Historical Database and create list s of all events which occurred within
a specific time span.
Spreadsheet logs are used to obtain data from, change, and put dat a into the Globa l database, a nd to load
the data into spreadsheets, allo wing you to format, st ore, and perform calculations us ing live process dat a.
Spreadsheet log configuration is perfo rmed using Microsoft
Spreadsheet logs are synchronized on a console group basis; that is, a spreadsheet log can be configured
or changed on any Micro-PWC in a console group, and the resulting changes will be copied to (synchronized with) all other Micro-PWCs in that console group, regardless of system type. This practice permits
backup of the information from any node. Note that only the configuration data which correspond s to the
type of spreadsheet on the local node (i.e., Microsoft Excel) will be useful locally.

✎ NOTES Logs are sent to a printer device when generated. If a “printer” has
been configured with a Device Type of “File” (see the Micro-PWC
Configuration Guide, or your system administrator), logs configured
to print to that printer will actually be sent to that file, rather than to
an actual hard copy printer.
Printers used to print scheduled logs must support PostScript.

6.0 Trend Displays
Three types of trend recording are available on the Micro-PWC:
• Current Trending
• Historical Trending
• Archival Trending
The current, historical and archival trending functions display the values of one or more points in an an alog
trend format similar to that presented by a conventional strip chart recorder.
A current trend for each point appears as a part of the point display. Current trends are not configurable,
and are not stored. Current trending for a point exists only when the point is on display. Refer to Section
4.0, Hierarchical Process Displays, for a discussion of Hierarchical Displays, including point displays.
Long term trending is handled separately and is available in two forms:
• Up to 10,000 (network-wide) historical trend displays are available on the Micro-PWC. The
configuration of these trends can be performed on any Micro-PWC, and then distributed to all
other Micro-PWCs within the same console-group. See the Micro-PWC Configuration Guide
for details on the trend configuration procedure.
• The Archive Database utility permits Historical data and Historical Block data to be transfe rred
to a removable storage media, creating a permanent record which can be retrieved and
displayed at a later date as the Archival (or Archival Block) database. Data from more than
one Archive tape can be restored; this material does not overwrite existin g archival data, but
rather is added to the existing data to become a part of the Archival Database. By clicking a
single button on a Trend display, the Archival Database can be specified as the data source,
providing access to Archival Trends for the points configured on the trend display.
Any point that exists in the Historical Database and which can be converted to a numeric value can be
trended.
Except for the text in the Database Select button, which indicates which database is being viewed
(HISTorical or ARCHival), the Archival Trend Display format is identical to that of the Historical Trend Dis-
play. This section details the use of the Trend Display.
To call up a Trend display, an Operator Window must be open and have keyboard focus. Click Select >

6.1 Trend Display Format
A Trend Display consist s of numerous parts, each of which is described in detail in the following paragraphs. Briefly, the central area of the display is a Trend Graph containing colored traces which represent
up to eight trendable variables.
Above the Trend Graph are eight sets of three buttons each, one set per trace. These buttons are used to
manipulate individual traces or to replace the default range of the Trend Graph with the range for an individual trace. Below the Trend Graph are additional buttons; these buttons, which include the
Compression, Zoom, Reset, Pause, and Segment buttons, affect all traces on the trend graph equally.
✎ NOTE The Zoom item on the Trend Display menu bar operates
independently of the Zoom button on the Trend Display itself, which
is described in Section 6.1.13, Zoom/Unzoom Button. Operation of
the menu bar Zoom is identical to that of the Zoom item found on
graphic displays, as described in Section 7.6, The Zoom Menu
Item.
6.1.1 Trend Graph
The Trend Graph p or tion o f th eTrend Display occupies the lower two thir ds of th e Operator Window. Up to
eight process variables can be displayed graphically as traces plotted on the Trend Graph. The vertical
axis represents the percentage of display range, while the horizontal axis depicts the time base in minutes.
Each process variable is plotted on the graph in a different color.
Using the Trend Readout arrow (displayed at the top of the Trend Graph), the operator can point to any
display value of a process variable on the graph. See Section 6.1.3, Trend Readout Arrow, for detailed
information on this item.
6.1.2 Time Base and Size of Display Window
The displayed time base of a trend display is separated into five sections, and is based on segment size.
Segment size is a user-configurable parameter, and is determined by the values entered to define the
number of SECONDS and the number of POINTS in a segment. The POINTS referred to here should not
be confused with the Historical Database point(s) for which values are being collected; rather, POINTS are
the values collected for the Historical Database point, which then become POINTS plotted as a trend trace.
(See the Micro-PWC Configuration Guide for details on trend configuration.) By default, the number of
POINTS and the number of SECONDS are both set to 60, and display as five 1 minute intervals (segments) on the Trend Graph.
The Micro-PWC locates the points which lie within each time interval. If one point is found, the value of the
point is used to plot it on the trend display. If more than one point exists within the interval, the assigned
Display Option (MINimum, MAXimum, AV eraGe , or INSTantaneous) is used to calculate one value from all
points which exist in the interval. This value is then plotted on the trend display. (If the INSTantaneous Display Option is used, the last value found will be used to plot the point on the Trend Graph.) The resulting
value is used to plot the point on the trend display. If no points are found in an interval, no point is plotted
for that interval.
This method of plotting trends permits greater flexibility in trend configuration. For example, points with different collection rates can be plotted on the same trend graph, and non- period ic dat a ca n also be trende d.
6.1.3 Trend Readout Arrow
The Trend readout arrow enables the operator to determine the collection time and value at any point
where the arrow intersects with the horizontal axis of the graph. TheTrend Readout arrow is controlled by
the L
EFT ARROW and RIGHT ARROW buttons, which bracket the Time At Arrow button, located above the upper
Trend Displays 59
Micro-PWC OPERATOR’S MANUAL
right corner of the Trend Grap h. Clicking either of the se A
RROW buttons causes the Trend Readout arrow to
move along the top of the T ren d Gra ph in th e in dicated di rection. Each time the button is clicked, the point
of intersection between the Trend Readout arrow and th e Trend Graph moves (in the d irection sele cted) to
the next valid location of a collected value on the display.
6.1.4 Time at Arrow Button and Arrows
The Time at Arrow button displays the specific time and date toward which the Trend Readout arrow is
pointing. The format used is HH:MM:SS DD-MMM-YY. This allows the operator to be precise when interpreting the data on the Trend Display. (When the display is refreshed, the arrows shift along with the trace
so that the display of the value for the time selected by the operator is maintained.)
To move the Trend Readout arrow to point to a new time and date, click on the Time at Arrow button. A
pop-up window appears (Figure 6-5) which contains an entry box and prompts for a new time and date.
(The Trend Readout arrow cannot be moved to a time prior to the beginn ing of a trend.)
TC00060A
Figure 6-5. Time Entry Window
The new time and date can be entered in the format shown (HH:MM:SS DD-MMM-YY). If a field is omitted
during entry, that field will default to the value used in the current Time at Arrow. (An exception to this rule
is the seconds (SS) field, which always defaults to 00 if no value is entered for the field.)
For example, if the current Time at Arrow is 10:17:32 30-JUN-05, then entering:
15-
will cause the Trend Readout arrow to move to 10:17:00 15-JUN-05.
It is also possible to move to a new time relative to that of the current Value at Arrows. To do so, prefix the
number to be shifted with a plus or minus to indicate in which direction the movement is to take place. For
example, to move the Trend Readout arrow to the point on the Trend Graph which is 10 minutes prior to
the current location, enter:
-:10
To move the Trend Readout arrow to the location five minutes after the current location, enter:
+:5
6.1.5 Trace On/Off Button
A set of three buttons is provided on theTrend Display for each of the eight possible trac es. The first button
in each set is the Trace On/Off button, which displays the index number of the associated trace and contains an ON/OFF indicator. The ON/OFF indicator is a red dot which is displayed when the trace is ON.
The indicator is not visible when the trace is OFF. Click the Trace On/Off button to cause the trace to toggle between the visible (ON) and invisible (OFF) states.
Each trace can be configured to be ON (visible) or OFF (invisible) by default when the trend is initially displayed. (The Micro-PWC Configuration Guide provides details on the configuration procedure.)

Option button allows you to select the option which determines the form in which data is to be presented
for that trace on the Trend Graph. These options include MINimum, MAXimum, AVeraGe, and INSTantaneous.
If MIN, MAX or AVG is selected, the data collected during the collection interval will be used to calculate
the value plotted on theTrend Graph . If INSTantaneous is selected, the actual value of the data at the time
of collection will be used to plot the value on the Trend Graph.
Click on the Display Option button to move through the choices. The face of the button will reflect the
current choice in effect.
6.1.7 Trace Scale Button
The Trace Scale button is the third button in the set of three associated with each trace. The face of this
button indicates the color in which the trace is displayed. Click this button to change the Scale Bar Limits of
the Trend Graph to reflect the specific High and Low limits for the associated individual trace. The new
Scale Bar Limits will be displayed in the same color as the trace with which they are associated. To restore
the original Scale Bar Limits, click Trace Scale a second time, or click Reset (see Section 6.1.14, Reset
Button).
6.1.8 Trace Tag and Atom
The tagname and atom of the Historical Database point which is being trended appear to the right of the
Trace Scale button.
6.1.9 Value at Arrow
To the right of the trace tag and atom is a value which represents the Value at Arrow. This is the value of
the Historical Database point trended by this trace at the time indicated by the location of the Trend
Readout arrow.
6.1.9.1 Value Precision Indicator
Due to differences in collection rates, it is possible that no point was collected on the precise point in time
indicated by the Trend Readout arrow. In this case, the value displayed is an interpolated value. The value
actually shown may have been collected slightly before or after the point in time indicated by the Trend
Readout arrow. The Value Precision Indicator is a one-character field which follows the Value at Arrow.
The character displayed here provides information regarding the precision of the value:
x Indicates a precise, actual value is displayed.
< Indicates that the time-st amp of the value displa yed is actu ally prior to (old er
than) that indicated on the Time at Arrow button (see Section 6.1.4, T im e at
Arrow Button and Arrows); or the Micro-PWC is unable to interpolate the
value.
> Indicates that the time-stamp of the value displayed is actually after (newer

• Range for the point
• Time-stamps of the first and last sample
• Controller tagname and atom
• Collection rate
• Storage rate
• Collection option (MIN, MAX, AVG, INST)
• Identity of node from which the point data was collected
• Identity of node on which the collected data was stored
• Historical database legend for the point

Click the entry box to call up the text entry cursor, then enter the compression value to be used. Click OK
to complete the operation. If the value entered is outside the range (0.05 to 50), the following error message will be displayed:
Value not in range
(0.05 - 50.00)
Click OK to close the pop-up. Also, if the combination of the segment size configured for the trend and the
Compression Value entered will result in too many points being plotted in a segment, the following error
message will be displayed:
Segment size too large
Click OK to close this error window, and enter a lower compression value. This condition can occur when
the configured segment size is larger than the default segment size (60 seconds).
Caution must be exercised when interpreting data displayed on a compressed display. By experimenting
with viewing the same trend display using a number of different compression ratios, it is easy to see that
although all the displays are correct representations of the compressed trend data, the traces displayed
may be deceiving if not viewed with care.
When the display options MIN, MAX, or AVG are in effect, rem ember that th e values of the point s betwee n
the displayed points could have varied widely. Even when INSTantaneous is the display option in effect, a
compressed display can be subject to misinterpretation. (The examples which follow in this section illustrate how this is true for instantaneous values.)
When viewing a compressed trend display of process variables, the value of which repeat over time, be
especially careful. “Aliasing” can cause the trace for the signals to appear as a straight line, as a magnified
duplicate of the original trace, even as a mirror image of the original trace.
To see the reason for the generation of these possibly misleading traces, the way in which compressed
displays are “drawn” must be considered. Every nth sample is plotted on the graph as a point, and the
points are connected by straight lines. There fore, the position of the extracted points along the original
trace will affect the shape of the trace on the new compressed display . For example, if an Historical trend is
Trend Displays 63

established to display a periodic signal which repeats every 60 seconds, and a collection rate of 10 seconds is configured, then the display will show six points per period of the signal (Figure 6-7).
Figure 6-7. Original Waveform
If this trend is compressed six times, the display will show only every sixth sample. The resulting display
will be a straight line since every sixth sample has the same value (Figure 6-8)
Figure 6-8. Compressed Waveform - 6:1 Compression
If the display is compressed seven times, the resulting display will be identical to the original, since the
value of the eighth sample (first sample plus 7) is the same as the value of the second, the value of the fifteenth point is the same as the value of the third, and so on. (Figure 6-9).

Micro-PWC OPERATOR’S MANUAL
6.1.12.1 Tre nd Compression Speed Factors
There are several factors which affect the amount of time necessary to perfor m trend compression. The
most important factor is the amount of data to be processed. To a lesser extent, both the location of the
data with respect to the location of processing, and the speed of the Micro-PWC performing the processing, have a measurable influence.
Trend compression time is base d on the amo unt of dat a tha t is processed. If all point s on the trend disp lay
contain the same amount of data to be compressed, each will take the same time to compress. However, it
is possible to have points with different densities displayed on the same trend (e.g., the trace from Pen 1
reflects data collected at 1 second intervals, while the trace from Pen 2 reflects data collected at 5 minute
intervals). When this situation exists, extra care is needed when comparing compression times.
Where trend compression is a common operation, it is better to do the compression in the Historical Database, in which case it is done as a background task. This is done via the configuration of the Historical
Database points, where the periodic collection rate (1 second, 2 seconds, etc.), the storage rate option
(1, 2, 5, etc.), and the collection option (minimum, maximum, average, or instantaneous value) are configured. (Historical Database configuration is discussed in the Micro-PWC Configuration Guide.)
Briefly , these configuration options make it possible to do much of the compression within the Historical
Database. For instance, an initial compression ratio of 10 to 1 can be achieved within the Historical Database by storing a value that is the average of 10 collection samples (collected at one second), and displayed on a Trend Display so that one value is displayed for each point on the plot. Subsequent
compression of the Trend Display using a compression ratio of 1:50 will be much faster, and will yield
exactly the same trace as that displayed when averaging of all collection samples and compression (u sing
a 1:50 compression ratio) are performed via the T rend Displ ay. By storing a value that is the average of 10
samples, the total amount of data extracted from the Historical Database and averaged is one tenth of
what would be required if every sample were stored and averaged on the Trend Display.
When the Micro-PWC on which the Historical Database dat a is stored is d if ferent from the M icro-PWC that
is controlling the Operator Window which contains the Trend Display, the data must travel across the system (ethernet) network in order to be displayed. This can cause a noticeable delay when there is a large
amount of data to be transferred. It can take more than twice as long to compress a large trend under
these circumstances. Using the Historical Database configuration to perform data compression as
described above and thus transferring less data across the network becomes even more important under
these circumstances.
The speed with which trend compression is performed is also affected by the speed of the Micro-PWC
computer being used to view the Trend Display. The processing speed of the Micro-PWC computer is
affected both by the load placed on the CPU and the type of hardware in which the Micro-PWC sof tware is
installed. Consult your system administrator if yo u have any questions about the hardware platform in use
at your site.

7.0 Using Graphic Displays
7.1 Introduction
This section describes the use of graphic displays on the Micro-PWC, including:
• Accessing graphics
• Control through graphics
• Display vectoring
There are 10,000 graphic displays available on the Micro-PWC. Graphics are configured (by the user) to
display process values, to allow for process values to be changed, and to provide a graphical representation of the process. A typical graphic, such as the example in Figure 7-1, contains a pictorial represent ation
of a section of the process in a plant, using symbols, bars, lines, text, and so on. All of the graphical objects
used in the group and point displays (such as pushbutton s, sliders, bargraphs, and tren ds) can be used on
graphics.
TC00063A
Figure 7-1. Typical Graphic Display
Values (such as temperatures, pressures, and alarm states) from the plant process can cause changes to
text, colors, or shapes on a graphic. Values are updated every second in the Operator Window which has
keyboard focus. In all other Operator Windows, updates occur every two seconds.
A graphic can contain pushbuttons and other objects which allow user interaction via the mouse and keyboard. For example, a graphic may contain a pushbutton with the label ACK, which appears when a point
Using Graphic Displays 69
Micro-PWC OPERATOR’S MANUAL
goes into alarm and which, when clicked, acknowledges the alarm. Two pushbuttons frequently used on
graphics are the Control pushbutton (see Section 7.2, Control Through Graphics) and the Display Vector
pushbutton (see Section 7.3, Display Vectoring).
7.1.1 Accessing Graphic Displays
Graphic Displays can be accessed using either the keyboard or mouse. Using the keyboard, with an
Operator Window open and with keyboar d fo cu s, pr es s F1. A pop-up window will appear, which allows the
user to enter the index number of the desired graphic display.
Alternatively, the mouse can be used (instead of F1) to display this window. Again, an Operator Window
must be open. From the Operator Window men u bar, select the sequ en ce Sele ct > Gra phi c. A pop-up window will appear, which allows the user to enter the index number of the desired graphic display.
If the number of the desired Graphic is not known, or if you wish to first view a list of a vailable Gr aphic Displays, click List on the window. The original window will be replaced by a new one titled Select Graphic
(Figure 7-2), which contains a list box which lists the num ber and legend of each availa ble Graphic Display.
TC00064A
Figure 7-2. Select Graphic Pop-up Window
Click the desired item in the list box to highlight it, then click OK to complete the selection operation, or
click Cancel to exit without selecting a Graphic. Other options on the Select Graphic window include the
Search button, which allows the user to search the list for a Graphic number, or an alphanumeric string
representing all or part of a Graphic legend; the Graphic with the specified number (entered in the Index
entry box) or the first entry encountered containing the specified string (entered in the title entry box) will be
placed at the top of the list. A Top button is also supplied; click this button to display the beginning of the
list in the list box.
✎ NOTE Searches using the Title text entry box are case sensitive.
After a graphic display has been selected, use P

7.2 Control Through Graphics
A process can be controlled from a graphic through the use of a Control pushbutton. The default label on
the button face is C, but buttons with other labels may be used. Typically, a Control pushbutton is located
near another graphical object on the graphic display, such as a valve, which is to be controlled
(Figure 7-3). A graphic display can contain more than one Control pushbutton.
TC00065A
Figure 7-3. Graphic Display with Control Pushbutton Labelled “M”
A Control pushbutton is configured with the name of the point (module) to be controlled. Clicking on a
Control pushbutton opens a pop-up Control wi ndow (Figure 7-4) containing a single-point group model for
this point.
TC00066A
Figure 7-4. Control Window
The appearance and use of the display in the Control window varies according to the Module Type of the
point, as described in Section 4.3.2, Group Display. Typically, the display in the Control window allows process values (e.g., a set point) to be changed by the use of sliders or pushbuttons. A pushbutton near the
top of the display contains the tagname of the point. Clicking this pushbutton closes the Control window
and replaces the graphic with the correspo nd i ng po i nt dis pla y.
The title bar of the Control window identifies its parent Operator Window by number. No more than two
pop-up Control windows can be open at a time from one Operator Window. Click OK to close a Control
window. The Control window can be moved and resized in the normal fashion.

Micro-PWC OPERATOR’S MANUAL
7.3 Display Vectoring
The Display Vector pushbutt on is shown in Figure 7-5.
TC00067A
Figure 7-5. Display Vector Pushbuttons
Display Vector (Vector) pushbuttons are incorporated in a Graphic when it is configured; for example, the
Graphic in Figure 7-1 contains Vector pushbuttons at the lower left side of the display.
Click a Vector pushbutton to change (vector) the display in the Operator Window from the current graphic
to a different display, which has been specified during configuration. This new display can be another
graphic, or a display of a different type. For example, one Display Vector pushbutton can be configured to
vector to Graphic #12 and another can vector to Summary #10. Typically, a label appears next to the Vec-
tor pushbutton, identifying the vector display.
By default, the new display appears in the window in which the Vector pushbutton is located; to cause the
new display to appear in a different Operator Window, drag the Vector pushbutton and drop it inside the
frame of the Operator Window in which the new display is to be viewed.
✎ NOTE Attempts to drop the display in anything other than an Operator
Window (e.g., a pop-up window, the System Window, and so on)
will cause the Micro-PWC terminal to beep and the operation to
terminate. Similarly, if the pointer is on an Operator Window frame
(instead of inside the window or on the title bar), the terminal will
beep and the operation will terminate

Micro-PWC OPERATOR’S MANUAL
7.4 Error Indication
If an error occurs when a graphic is on display, the error indicator (Figure 7-6) appears in the center of the
Operator Window.
TC00068A
Figure 7-6. Error Indicator
Click on the error indicator to open a window, titled DBA Errors, which contains messages describing the
error(s). The following are the most common causes of errors:
• A process value used by the graphic cannot be accessed. The message supplies further
details on the problem.
• The graphic was not configured completely. This results in “variable not defined” messages.
To quickly determine which object on the graphic is associated with a particular error message, click the
message in the DBA Errors window. The associated object on the graphic will flash rapidly several times in
response. Be aware that the flashed object ca n be hidd e n be hind the DBA Errors window. If no object
appears to flash when the error message is clicke d on , mo ve the DBA Errors window and click the error
message again.
The error indicator always appears in the center of th e graphic. If you have used the Zoom/Pan feature, the
error indicator may not appear on the visible part of the graphic. Similarly, use of Zoom/Pan may cause the
flashed object to be outside the visible part of the graphic. Use the Zoom To Fit function to assure that the
entire graphic is visible in the Operator Window.

7.5 Alarm Acknowledgment
A graphic can allow alarm acknowledgment. For example, a grap hic can be configured so that a pushbutton labelled ACK appears when a point in alarm needs acknowledgment. Click the pu sh button to ackno wledge the alarm and remove the pushbutton from the d isp la y. Note that this is a user-configurable option; if
you have questions on how graphics have been configured on your system, consult your system administrator.
Alarms can also be acknowledged from a graphic by pressing A
Window > Acknowledge from the Operator Window menu bar. Each point which needs acknowledgment,
and whose ACK atom is referenced by the graphic, is acknowledged.
LT-F10 on the keyboard, or by selecting
7.6 The Zoom Menu Item
By default, the entire Graphic Display is always shown in the Operator Window when the graphic is first
called up.
The Zoom item on the menu bar of the graphic display provides access to th e Zo o m an d Pa n op erat i on s,
which are used to change:
• The portion of the Graphic which is visible in the Operator Window (Pan).
• The amount of the Graphic Display which can be visible in th e Operator Window, known as the
view size (Zoom).
The view size always has an Aspect Ratio 4 (wide) by 3 (high), to maintain correct proportions of models
during scaling operations.
To access the Zoom and Pan functions, click Zoom on the menu ba r of th e graphic d isplay. The Zoom/Pan
window (Figure 7-7) will be displayed.
TC00069A
Figure 7-7. Zoom/Pan Window
The top portion of the Zoom/Pan window provides PAN functions, while the bottom part of the window is
devoted to the ZOOM operation.
If the Zoom/Pan window is on display and the display in the Operator Window is changed to any type of
display other than another Graphic or a Trend, Group or Point display, the Zoom/Pan window will automatically be closed.
74 Using Graphic Displays
Micro-PWC OPERATOR’S MANUAL
✎ NOTE Changes to the view size made in a graphic will not be saved as
part of a CRT Context Key or Quick Key setting; when a graphic
display is called up by either of these methods, a zoom-to-fit
operation (described in Section 7.6.2, The Zoom Operations: In,
Out, Fit, Pick) will automatically be performed.
7.6.1 The Pan Operations: Up, Down, Left, Right, Center
The Pan operations (Up, Down, Left, Right, Center) are used to change the portion of the view shown in
the Operator Window; they do not change the view size.
Each of the Pan functions is represented on the Zoom/Pan window by a button. The face and location of
the button indicate its function. The face of each of the directional operations (Up, Down, Left, and Right)
contains an arrow pointing in the appropriate direction, and each button is located in the appropriate position around the Center button. The face of the Center button contains a bull’s eye.
Each click on one of the directional Pan buttons moves the visible portion of the view in the selected direction by 1/3 of the corresponding view dimension.
After the Center button is clicked, the pointer assumes the shape of a bull’s eye. The next click in the
graphic display will center the view on the point clicked.
7.6.2 The Zoom Operations: In, Out, Fit, Pick
The Zoom operations (In, Out, Fit, Pick) change the apparent size of the graphic which appears in the
Operator Window.
A Graphic Display can have a maximum size of 400 by 300 units, and a minimum size of 20 by 15 units.
The number of units in a graphic is n ormally invisible to the user, except during configuration (discussed in
the Micro-PWC Configuration Guide) because installed graphics are automatically zoomed to fit when
loaded in the Operator Window. Attempts to Zoom In or Out beyond the minimum or maximum size of a
graphic display will have no effect, and the view size will remain at the minimum or maximum.
Each time Zoom In is clicked, the view size is reduced by 62%. The center of the view remains unchanged.
Objects in the graphic which are visible appear correspondingly larger. If the view has been fully zoomed
in, no further change occurs to the view size.
Each time Zoom Out is clicked, the view size is enlarged by 62%. The center of the view remains
unchanged. Objects in the graphic which are visible appear correspondingly smaller. If the view has been
fully zoomed out, no further change occurs to the view size.
Click Zoom Fit to adjust the view size by automatically zooming out (or in) so that the entire model is visible and fills the Working View . If t here are no objects out side the current view size, the view size will “zoom
in” in order to make the objects present fill the Operator Window. (However, it will not zoom in beyond the
default view size, which is 100 by 75 units.) Each time an installe d graphic is displaye d in an Operator Window a Zoom Fit operation is automatically performed.
The Zoom Pick button allows you to select two diagonal corners (e.g., the lower left and upper right corners) of the box which encompasses the desired view size. The rect angle resulting fr om these selections is
called the zoom box. If a zoom box is smaller than the minimum permissible view size, the view size will
remain unchanged.
Using Graphic Displays 75
Micro-PWC OPERATOR’S MANUAL
✎ NOTE The contents of the Graphic display in the Operator Window after a
Zoom Pick operation may not reflect exactly the contents of the
zoom box used to make the selection. This is because the graphic
is restricted to an aspect ratio of 4 (wide) by 3 (high), while the
zoom box is not. In order to reconcile the two, the 4 x 3 aspect ratio
is applied to the largest dimension of the zoom box selected by the
user.
7.6.3 Zoom and Pan Operations in Pop-up Graphic Windows
Zoom and Pan operations are also available in pop-up gra phi c wind o ws whic h ar e ac ce sse d via Mod el
Pop-Up pushbuttons appearing on Graphic Displays. A Zoom button appears at the bottom of such pop-
up windows; click on it to access the Zoom/Pan window. The Zoom and Pan operations can be performed
as described above. A Zoom to Fit operation is automatically performed on such windows when they are
first displayed.
✎ NOTE Zoom/Pan operations are not available in pop-up controller
windows.
7.6.4 Resizing the Zoomed/Panned Operator Window
When an Operator Window (or pop-up g raph ic windo w) is resized, the view size is not changed. However,
if the shape of the window is changed (i.e., made narrower, wider, taller, or shorter), more of the view may
be visible than before. The objects in the view will appear larger if the window is made larger, or smaller if
the window is made smaller.

8.0 Process Alarms
8.1 Introduction
A Process Alarm is generated when a process variable is in an abnormal condition. Process alarms are
displayed in the first two lines of the Mini-Alarm Window an d ar e acc om panied by au dib le alarm s . A complete list of Process Alarms is contained in the Alarm Review display. Like other messages generated on
the system, Process Alarms are stored in the Historical Database and can be viewed on a Micro-PWC, or
logged to a printer using the Event Historian (refer to Section 9.0, Events). Process Alarms can also be
logged to a printer as they occur.
8.2 Mini-Alarm Window Title Bar
The title bar in the Mini-Alarm Window identifies the win do w by th e Micr o -PWC nam e . The na m e of th e
current host node is displayed to the right of the Micro-PWC address. The title bar also contains a string
which can be configured to provide further information, such as plant name and location. The login name
of the user currently logged in on the Micro-PWC appears on the title bar, followed by the More Alarms
(+ALARMS) indicator (if more alarms exist), a Silence button and the Filter button. The Silence button
contains a horn icon on the button face, and is visible only when audible alarms exist.
8.2.1 Alarm Indicator
The +ALARMS indicator is located on the Mini-Alarm Window title bar, immediately to the right of the login
name of the user currently logged in on the Micro-PWC. This indicator appears when more process alarms
exist than can be shown in the alarm display area (i.e., when there are more than two process alarms).
Process Alarms 77
Micro-PWC OPERATOR’S MANUAL
8.3 Process Alarms in the Mini-Alarm Window
Process alarms are displayed in the top two lines of the Mini-Alarm Window. If more unacknowledged process alarms exist than can be displayed in the Mini-Alarm Window, then the message +ALARMS appears
in the title bar of the Mini-Alarm Window.
8.3.1 Process Alarm Priorities
Sixteen levels (from 1 to 16, with Level 1 being the highest) are available for use in prioritizing alarms.
The priority determines the importance of an alarm and the position in which it is displayed in the Mini-
Alarm Window. The priority also determines the color in which the alarm is displayed, and the type of audible alarm which accompanies it.
8.3.2 Audible Alarm Format
Audible Alarms are available in two formats on the Micro-PWC:
• Steady beep
• Rapid beep
The rapid beep is used for alarms with a high priority, while the steady beep is used for lower priority
alarms. The priority level which marks the division between the high and lower priority audible alarm formats can be configured by the user, as described in the Micro-PWC Configuration Guide. For details on
the configuration of this item on your system, consult your system administrator.
✎ NOTES Data contained in the Mini-Alarm Window is automatically filtered
by the filtering mask configured for the user currently logged in on
the Micro-PWC, and by any additional filtering performed by the
user (see Section 8.3.4, Filtering Alarms in the Mini-Alarm Window).
This means that not all users will necessarily receive the same set
of alarms and messages. When there are no unacknowledged
process alarms, system events, or messages in the Mini-Alarm
Window on a particular Micro-PWC console, the audible alarm will
be automatically turned off for that user until the next
unacknowledged alarm or message appears in the Mini-Alarm
Window.
Note that there can still be unacknowledged alarms on the
system that are not visible on the user's screen, due to the
filtering configuration.
A Silence button (with a horn icon on the button face) appears on
the Mini-Alarm Window title bar when audible alarms exist. This
