Introduction

Low-end units

The Touch Panels TP170 A and TP170 B, and Operator Panel OP170 B represent
products in the new series of low-end operating units. The units in this series are
based on the innovative standard WindowsR CE operating system. They complete
the SIMATIC HMI product range in the low-end sector. The TP170 A is a low-price
initial unit which can operate with all SIMATIC S7 CPUs. The TP170 B and
OP170 B fulfill all sophisticated functional requirements.

This new product series enables self-created graphics, digital photos and scanned
screens to be integrated in a project. Bars and trend curve diagrams can still be
used to graphically display temperature progressions, for example.
The units are equipped with an interface for MPI and PROFIBUS-DP. This
interface is also used for downloading configurations. The unit memories are
designed for small to medium-size configurations.

Here is a short selection of common features:

S Automatic transfer detection for downloading configurations

S Password protection

S Input/Output fields to display and modify process parameters

S Configurable buttons and function keys (OP170 B) to control input/output and

data bits

S Bars for the graphical dsplay of dynamic values

S Standard library for graphics and buttons can be used under ProTool CS

S Graphics can be configured to label buttons or as format-filling background

screens

S Fixed text for labeling buttons, process screens or process values in any

character size

Additional features with TP170 B and OP170 B:

S Print functions

S Trends

S Scheduler

S Recipe management

S Backing up recipe data and configurations on optional memory cards (CF card)

A complete overview of the functional range of the units is provided Chapter 2.

Introduction

Area of use of the units

The units have been conceived for easy machine operation and monitoring. They
provide a realistic graphical representation of the machine or system to be
monitored. Their area of use include implementation in machine and apparatus
construction as well as in the packing and electronics industry.

The high degree of protection (IP65 on the front side) and non-implementation of
moving storage media, such as hard disks and floppy disks, ensure the operating
units are also suitable for use in rough industrial environments and directly on site
on the respective machine.

Installation locations for the units include:

S Panels

S Consoles

As a result of their minimum installation depth, the units are particularly suited for
operation near the machine.

Easy to operate and observe

The units enable operating statuses, current process values and errors concerning
a connected PLC to be graphically displayed and the relevant machine or system
to be easily monitored and operated. Display and operation of the units can be
adapted optimally for the respective process requirements by using the
configuration software ProT ool CS.

Theunitscanbeusedto:

S control and monitor the process by means of the menu system. Setpoint values

or control element settings, for instance, can be modified by entering values or
activating configured function keys;

S display processes, machines and systems on full-graphic, dynamic screens;

S display and edit messages and, for example, process tags in output fields, and

to visualize bars or status display;

S to intervene directly in processes via the Touch Screen (TP170 A, TP170 B) or

using the integrated keyboard (OP170 B).

Configuring using ProTool/Pro CS, ProTool and ProTool/Lite

Graphics, texts and operating and display elements which need to be represented
on the operating units must first be created on a configuration computer (PC or
PU) using the configuration software SIMATIC ProTool/Pro CS, ProTool or
ProTool/Lite. The configuration computer must be connected to the operating unit
in order to download the project to the operating unit (refer to “Configuration
phase” in Figure 1-1).

Once the project has been successfully downloaded, connect the operating unit to
the PLC. The operating unit can then communicate with the PLC and respond
according to the information configured for running the program in the PLC (refer to
“Process control phase” in Figure 1-1).

3.5 Download Back (TP170 B and OP170 B)

Purpose

During downloading, generally only the run-capable project (*.fwd) which has been
generated is downloaded on the operating unit. If the original project file is to be
used for further development of the project or for fault analysis, it must remain on
the configuration computer.

Not only the generated project can be stored on the TP170 B and OP170 B units,
but also the project source file (*.pdb), so that it can be retrieved (downloaded
back) from the operating unit later, if necessary.

Advantage

After downloading a project back, it can be analyzed and modified even if the
original configuration computer cannot be accessed or the source file (*.pdb) on it
for the project is no longer available.

Conditions

The following conditions must be fulfilled in order to retrieve the source file from the
run-capable project file:

S The operating unit must be equipped with a memory card.

S Downloading of the current project file from the configuration computer to the

operating unit must be performed using the option Download Back Enabled.

What happens during download/download back?

In the case of downloading including transfer of the source file, the project is
compressed from the source format (*.pdb) and downloaded to the operating unit
as a *.pdz file. After downloading back, the file is decompressed in the ProTool CS
configuration software.

The project must be given a new name on the configuration computer.

Note

S The downloaded back, decompressed project file (*.pdb) can only be opened

with a ProTool CS whose version number is greater or equal to that of the
configuration software with which the project was created.

S ProTool CS cannot check whether the source file on the operating unit matches

the project actually run on it. If downloading is performed at any time without
the option “Download Back” being activated, it is possible that old project data
is on the operating unit which no longer matches the current project.

6.1 General Operation

In this chapter

This chapter contains information on how to operate screens and logging in and
out of the operating unit.

6.1.1 Operating Screens

What is a screen?

Screens visualize the progress of processes and display specified process values.
A screen contains logically related process data which the operating unit can both
display and modify by operating the individual values.

Screen partitions

A screen is basically composed of static and dynamic sections. The terms “static”
and “dynamic” do not refer to the possibility of dynamically positioning screen
partitions but to the connection to the PLC.

Static partitions, e.g. text and graphics, are not updated by the PLC. Dynamic
partitions, e.g. input and output fields, trend view and bars, are linked to the PLC
and display current values constantly read in from the PLC memory. Their
connection to the PLC is established by means of tags.

A summary of all the screen objects which the operating unit may contain is
provided on Page 6-4.

Select screen

There are several ways in which to select a screen:

S Button

Pressing a button opens the corresponding screen defined in the configuration.

S Input field

Enter the corresponding number of the screen to be viewed in the input field.

6.1.2 Logging On and Off from the Operating Unit

Purpose

During the configuration, input fields and buttons can be protected against
unauthorized operation by assigning passwords. Important parameters and
settings can then only be modified by authorized personnel. The password is
defined at the moment the element is configured and cannot be modified via the
operating unit.

Login

If operating elements are to be assigned password protection in the configuration,
it must be possible for the operator to log in. In this case, the function Login_user
must be linked with an operating element, preferably an input field, in the
configuration.

Logoff

In order to access a password protected operating element during runtime, it is
necessary to log in on the operating unit. It is then possible to access all password
protected operating elements up to the point of logging off from the operating unit.

When correspondingly configured, it is also possible to log on via an input field for
confidential password entry. The character string entered is represented by
placeholders (*).

In order to rule out operation by unauthorized personnel, the login should not
remain active on the operating unit for too long a period of time. The following
options are available with which to log off from the operating unit:

S Configured logout time expires

If the operating unit is not operated by the user within the configured period
(logout time), he is automatically logged off from the operating unit.

S Log out of the operating unit

If the configuration links the function Logoff_user with an operating element, the
element can be used to log off from the operating unit.

Tip

It is possible to log off by entering an incorrect password.

6.5 Status Button

Purpose

The Status button is an operating and display element with the two states Pressed
and Released. Status buttons indicate the status of a unit which cannot be
determined from the operating unit (e.g. a motor). At the same time, it is also
possible to change the status of the unit concerned on the operating unit.

Behavior

The behavior of the Status button can be configured:

S Switch:

The switch has two stable states. It toggles from one state to the other each
time it is operated, and remains in the respective state until it is operated again.

S Key:

The button has a fixed, stable home position. When operated, it switches to the
status pressed and remains in this state as long as it is kept pressed. When
released, it automatically switches back to its released position.

Display

Functions which have been assigned to the Status button can be triggered, for
example, by the following configurable events:

S Status change
S Printing
S Releasing

If the status of a switch type Status button changes as a result of a modification of
configured tags, not through operation, the corresponding function is not executed.

The two indicator statuses of the types Switch and Button with acknowledgement
can be assigned different texts or graphics in /Pro CS which are displayed on the
Status button during runtime.

6.6 Messages

What are messages?

Messages which appear on the operating unit indicate events and statuses related
to the control process and operating unit itself. A message can contain text and
tags.

The TP170 A differentiates between event messages and system messages:

S Event messages

indicate a status in the process, for example, Motor ON.
Event messages are configured. They are triggered when a bit is set in the
PLC.

S System Messages

are triggered by the operating unit. They are not configured.
System messages indicate, for example, incorrect operations or communication
faults. A time period can be considered for system messages in the
configuration software. This defines how long a system message appears on
the operating unit.

Screen Objects for TP170 A

A list of the most important system messages is provided in the Appendix C.

Message events

These messages are triggered according to events. Message events on the
TP170 A include:

S Message arrival

A message which has been triggered is considered as having arrived. As soon
as message is triggered, it is displayed in the operating unit message view and
is then considered as queued.

S Message departure

A message is considered as having departed when its configured time period
has expired or the event causing the message is no longer present. As soon as
a message has departed it is deleted from the message view.

6.7 Bar graphs

Purpose

Bar graphs present a value in the form of a rectangular area. The operating unit
thus provides a clear indication of how far the current value is from the limit values,
or if a setpoint value has been reached, at a glance. Bar graphs can be used to
display fill levels or quantities, for example.

Display

It is possible to configure minimum and maximum values and the direction a bar
graph moves by increasing the tag value:

Figure 6-2 depicts the various states of a horizontal bar graph:

that can be assigned one or more functions,
depending on the configuration. After pressing the
button, the functions configured for the event press are
triggered. On releasing the button, the functions
configured for the event release are triggered.

A Status button is a display and operating element
which has one of two states: Touched and Untouched.
The states can be indicated by means of text or
graphics.

The Status button can be configured to be locking
(switch function) or non-locking (keying function).

A switch serves to enter and display a binary status. It
can only be switched on or off.

An invisible button is a transparent button that is not
displayed on the operating unit. If invisible buttons are
located over graphics, for example, it is possible to
operate part of the graphic, e.g. a motor or valve.

After pressing the button, the functions configured for
the event press are triggered. On releasing the button,
the functions configured for the event release are
triggered.

A trend view provides a particularly clear
representation of process data when displayed as a
continual progression.

simultaneously in the trend view.

Bars represent values from the PLC as rectangular
areas. The operating unit thus provides a clear
indication of how far the current value is from the limit
values, or if a setpoint value has been reached, at a
glance. Bars are often used to represent fill levels or
workpiece numbers.

Direction, scaling, bar and background color and
labeling the Y-axis can be configured as required. In

7.5 Buttons

Purpose

A button is a virtual key located on the operating unit screen. Functions which have
been assigned to buttons can be triggered, for example, by the following,
configurable events:

S Clicking
S Pressing
S Releasing

Display

S Labeling

Buttons can be labeled statically or dynamically. In the case of dynamic
labeling, the text or graphic on the button changes during runtime according to
the value of a configured tag.

S Operation acknowledgement

As soon as the operating element detects a valid operation, it responds with a
visual acknowledgement. The acknowledgement, however, does not infer that
the required action is actually being executed.

Figure 7-1 illustrates an example of a button when pressed (right) and not pressed
(left).

Figure 7-1 Example of a button

Hidden buttons

Hidden buttons are transparent buttons which may lie over graphics, for example.
This enables plant parts which are graphically displayed on the operating unit to be
operated easily (e.g. a motor or valve). If a hidden button is selected on the
operating unit, its contour becomes visible as long as the button remains selected.
The contour enables the user to detect the operable area of the button.

Operation

S Key operation

Select the button, e.g. using the cursor keys and press either the Enter key or
Spacebar.

S Touch operation

7.6 Status Button

Purpose

The Status button is an operating and display element with the two states Pressed
and Released. Status buttons indicate the status of a unit which cannot be
determined from the operating unit (e.g. a motor). At the same time, it is also
possible to change the status of the unit concerned on the operating unit.

Behavior

The behavior of the Status button can be configured:

S Switch:

The switch has two stable states. It toggles from one state to the other each
time it is operated, and remains in the respective state until it is operated again.

S Key:

The button has a fixed, stable home position. When operated, it switches to the
status pressed and remains in this state as long as it is kept pressed. When
released, it automatically switches back to its released position.

Screen Objects for TP170 B and OP170 B

Display

Functions which have been assigned to the Status button can be triggered, for
example, by the following configurable events:

S Status change
S Printing
S Releasing

If the status of a switch type Status button changes as a result of a modification of
configured tags, not through operation, the corresponding function is not executed.

The two indicator statuses of the types Switch and Button with acknowledgement
can be assigned different texts or graphics in /Pro CS which are displayed on the
Status button during runtime.

7.7 Switch

Purpose

A switch serves for the input and output of a binary status. It can only be switched
on or off. It is linked to a tag to do this. The status OFF corresponds to the value 0
(a logical FALSE) of the tag linked to the switch. All tag values other than zero (a
logical TRUE) are interpreted as the status ON.

Behavior

Functions which have been assigned to the switch, can be triggered, for example,
by the following, configurable events:

S Change of status
S Switch on
S Switch off

If the switch status changes due to a change of the configured tag, none of the
events described is triggered.

7.8 Messages

Message categories

Messages indicate control-process events and states on the operating unit. The
operating unit differentiates between the following message categories:

S Event messages

indicate a status in the process, for example, Motor ON. Event messages are
configured.

S Alarm messages

indicate an equipment failure, for example, Motor temperature too high.
Alarm messages are configured. Alarm messages must be acknowledged due
to their critical nature.

S System messages

are triggered by the operating unit. They are not configured. System messages
indicate, for example, incorrect operations or communication faults. A selection
of important system messages is provided in Appendix C.

S S7 system messages

provide information on the status of the SIMATIC S7. They are not configured in
the ProTool CS configuration software. Refer to the S7 manual for the error
number indicated on the operating panel to determine the cause of the error.

Acknowledging alarm messages

Alarm messages must be acknowledged due to their importance. This
can be done manually on the operating unit or automatically by the PLC.
The message indicator depicted continues to be displayed as long as
alarm messages are still present on the operating unit when this feature
has been configured.

In order to acknowledge alarm messages on the OP170 B manually,
press the key depicted on the right. The LED integrated in the key lights
up when unacknowledged alarm messages are present.

In the case of the TP170 B, the message indicator can be operated.

Operating the message indicator on the TP170 B

The response of the message indicator is dependent on whether or not alarm
messages are present on the TP170 B which still have to be acknowledged at the
moment the indicator is touched.

S No alarm messages to be acknowledged:

The alarm message page is opened after operating the message indicator
(Page 7-19).

S Alarm messages to be acknowledged:

The alarm message window is opened after operating the message indicator
(Page 7-17).

Use the button illustrated to close the alarm window in order to operate
screens. The alarm message window can be opened again by touching the
message indicator.

Buffering messages

All message events (arrived, departed, acknowledged) are stored in an internal
volatile buffer. If a message archive has been configured, the message events are
also stored in this message archive.

Display messages

The events stored in the message buffer can be displayed according to different
criteria. The following predefined objects are available for display purposes:

Deleting messages

All message events concerning event and alarm messages are automatically
stored in the message buffer. There are two methods of deleting messages from
the buffer:

S Automatic deletion on buffer overflow

When the message buffer is no longer capable of accepting new message
events, the operating unit automatically deletes a number of message events
until the configured remaining buffer capacity is reached. In this case, the oldest
messages are deleted first.

S Deletion by operating the operating unit

In order that messages can be deleted manually from the message buffer, the
function Clear_message_buffer must be available in the configuration. In this
way, the following message categories can be selected for deletion according to
the configuration:

-- All messages

-- Alarm messages

-- Event messages

-- System messages

Print messages

When correspondingly configured, event messages can be printed out directly
when the message events Arrived and Departed occur, and also alarm messages
when the event Acknowledged occurs. System messages are not logged.

Information on setting printer parameters is provided in Chapter 9-12.

7.8.1 ALARM_S

Definition

ALARM_S is an active message procedure. If an alarm occurs, the CPU actively
issues the respective message to all the network participants which are logged on.
This means that the operating unit is relieved of continuous polling of the message
area.

Configuring ALARM_S messages

ALARM_S messages are not configured in ProTool CS but in STEP 7. The
message numbers are automatically assigned during configuration in STEP 7. The
unique assignment of the message text is made according to these numbers.

The display of ALARM_S messages on the operating unit can only be configured
when a SIMATIC S7 PLC is used and the /Pro CS configuration software has been
integrated in STEP 7.

Note

Detailed information on the configuration of ALARM_S messages is available in the
ProAgent/MP and ProAgent/PC user guides.

Restarting S7 CPUs:
Depending on the hardware configuration of the CPUs, it is possible that under
certain circumstances all queued ALARM_S messages will be deleted when S7
CPUs are restarted. Older stocks of S7 300 CPUs cannot inform the operating
units involved of the restart. The result of this is that messages are indicated on
the operating unit as being queued although the CPU has already deleted them.

Remedy:
Restart the operating unit.

7.12 Password List

Purpose

While the system is being configured using ProTool CS, operating elements can be
protected against unauthorized use by means of passwords. Important parameters
and settings can then only be modified by authorized personnel.

Password hierarchy

Hierarchically defined password levels from 0 to 9 exist for password protection
purposes. When a password is assigned to an individual user or to a whole user
group, the permission to execute functions at a specific level is assigned
simultaneously. If, for example, a user is assigned to password level 4,heorsheis
authorized to execute functions of password levels 0 to 4.

Password level

Password level 0:

This minimum password level is assigned to functions that have no, or only a
minimal effect on the course of the process. In order to trigger functions assigned
to Password Level 0, no password needs to be entered.

Password levels 1 to 8:
Functions are assigned to levels 1 to 8 according to their increasing importance.
The operating unit requests a password before a function with a password level
higher than 0 can be executed.

Password level 9

Only the supervisor (system support specialist or service technician) is granted
authorization to execute functions assigned to password level 9. The supervisor is
authorized to access all the functions on the operating unit.

Logging in on the operating unit (login)

After calling a password-protected function, the operating unit automatically
prompts the user to enter a password. Once entered, the password need not be
entered again in order to call in other functions of this password level or lower.

When correspondingly configured, it is also possible to log on via an input field for
confidential password entry. The character string entered is represented by
placeholders (*).

Logging off from the operating unit (logoff)

In order to prevent the software from being used by unauthorized persons, a
password level higher than 0 should not be left active on the operating unit over a
longer period of time. The following options are available to explicitly reset
passwords levels:

S Configured logout time expires

If the operating unit is not operated within the period of time configured (logout
time), the current password level is automatically reset to 0.

S Manual logout

If the function Logoff_user is linked to an operating element in the project, it can
be used to reset the current password level to 0.

Tip

It is possible to log off by entering an incorrect password.

Password management

Screen Objects for TP170 B and OP170 B

The operating unit can be used to enter individual members of staff in a password
list and assign password levels to them, according to their respective level of
responsibility. When processing the list, conclude each field entry by pressing the
Enter key. The password list contains all the passwords configured on the
operating unit. The list is coded and stored on the operating unit, protected against
a power failure.

Figure 7-10 illustrates an example of a password list with six entries.

Figure 7-10 Example of a password list

View password list

Only those passwords are displayed which have a password level equal to or lower

Creating a password

The user can only edit the password list up to the level with which he is currently
logged in. All passwords used in the system must be unique. It is not possible to
assign identical passwords to different users. It is possible, however, to assign the
same password level to different users without any restrictions.

Deleting a password

To delete a password from the password list, overwrite the password level
assigned to it with 0.

Export/Import password list

If a system includes several operating units which are accessed by the same
users, the same passwords must be installed on each operating unit. In order that
the password list need not be re-entered on each operating unit, it can be created
on one unit and imported onto other units.

In order to be able to export/import password lists on the operating unit, the
function Import_export_passwords must be linked to a button or function key, for
example. The file name of the password list to be exported/imported must be
specified as the function parameter during configuration.

Note

The password list is coded. It cannot be edited with external tools.

Recipes for TP170 B and OP170 B

S Recipe

Recipes correspond to the individual drawers if the filing cabinet illustrated (e.g.
grapefruit or lemon). The reference value fields (tags) belonging to the particular
recipe are defined in each drawer. The recipes define the data structure in
ProTool CS. This structure cannot be subsequently modified on the operating
unit.

S Data record

Data records correspond to the filing cards in the individual drawers of the
cabinet (e.g. Drink, Juice and Nectar). A data record contains the values for a
recipe. Data records are created, modified and deleted on the operating unit.
The data records are also stored on the operating unit. This saves storage
space o the PLC.

The Import/Export function provides the additional option of using external tools
to edit exported data records and then reimporting them on the operating unit.

Example of a recipe

An example for use of a recipe is its application on a filling station of a fruit juice
system. The same filling station is used to produce orange drink, orange juice and
orange nectar. The mixing ratios are different for each product. The ingredients are
always the same.

Assume that a recipe called Mixture is created, which has the following data
structure:

Tag Name

Var_2 l orange

Var_3 l water

Var_4 kg sugar

Var_5 g flavor

The designations l Orange, g Aroma etc. of the tags are the so called entry
names. The entry names are also displayed on the operating unit. In this way, for

example, the tag Var_2 can be identified as the tag designating the mixture
component Orange.

The data records contain the values for the different drink types. The data records
may appear as follows, for instance:

Orange drink Orange juice Orange nectar

l orange 90 l orange 95 l orange 70

l water 10 l water 5 l water 30

kg sugar 1.5 kg sugar 0.5 kg sugar 1.5
