The MicroView Programming Software (DPS) is a self-prompting, menu driven package that allows you to create and edit applications for the MicroView operator terminals. DPS does not require any programming knowledge.

2-2 Installing and Running the MicroView Programming Software

System Requirements

MicroView Accessories

Verify your computer is properly configured with the following:

• IBM PC/AT or 100% compatible

• 640K RAM (minimum)

• One or two diskette drives (1.44 Mb minimum)

• One fixed (hard) disk drive recommended. Required if only one

diskette drive is present.

• DOS version 3.2 or later

• Serial communications port (COM1 or COM2)

RS-232C

• Monochrome or color monitor (color monitor is recommended).

For application program transfers, you need a programming cable (Catalog No. 2707-NC8) to connect the computer to the MicroView communications port. You also need an external power supply to power the MicroView for program uploads and downloads. Refer to the MicroView User Manual (Catalog No. 2707-UM005B-EN-P) for additional download/upload information.

Making a Backup Copy

Installation Files

Make a backup copy of the MicroView programming software diskette. Insert the supplied disk into the diskette drive and use either the DISKCOPY or COPY command of your installed DOS version. Refer to your DOS manual for information and procedures regarding these commands.

After you have created a duplicate disk, store the original in a safe place and use the backup disk for normal operations.

The files on the installation disk are compressed and remain compressed until they are installed. Once installed, the following files are contained in the subdirectory:

DPS.EXE – MicroView Programming Software

DPS_CFG.EXE – DPS Configuration Utility.

Moving Around Screens

Linking Application Screens

DPS uses menus to guide you through the application development process. Select a menu item and the next menu or screen is displayed. The standard keyboard operations are:

Use these keys: To:

[

] [] [] []

[Return] Select a menu item. [Esc] Return to the previous menu.

MicroView application files allow you to present screens in a meaningful sequence, a hierarchy of possible tasks and operations. To do this, you will need to specify a link for each screen.

The linking function is the basis of a MicroView operator terminal’s power and flexibility. When screens are linked, the MicroView becomes an interactive operator workstation, one that can guide an operator through a hierarchy of operations. This hierarchy can be as simple or as complicated as your application requires.

Highlight a menu selection.

Note: All application screens must be created before they can be linked.

Data Scaling

Data entered by an operator can be scaled from engineering units such as gallons or PSI to machine control values. Likewise, data displays can take raw numeric values and scale them so they are displayed in engineering units.

Scaling of data is accomplished by defining a proportional ratio between the register value range and the display or entry value range. If a 1:1 ratio exists, the MicroView displayed or entered value equals the controller register value.

Here is an example of scaling using a data display to scale a register data range of 0 to 4,095 to a MicroView display range of -100 to +300.

Controller

Display Limits

+300

This Value is Displayed:

-100

SCALING

If the Display Register Contains:

4,095

SCALING

4,095

2,047

Publication 2707-PM002B-EN-P

When the ratio between the controller register values and MicroView display or entry values is not a multiple of 2, the value is rounded. Rounding may result in a 1 count error. Depending upon the direction of the scaling, this means that:

• The MicroView display value may be off by 1 when the

controller register value is scaled

• The controller register value may be off by one when a

MicroView data entry is scaled.

An error screen appears if a rounding error occurs at the end points of a data range. You must either increase the minimum or decrease the maximum range of either the controller register or display ranges.

Designing Microview Applications 3-5

Scaling Formulas

The scaling formula for a MicroView display value is:

Displayed Value = m x Register Value + b

Where:

Display Maximum Value - Display Minimum Value

m =

Register Maximum Value - Register Minimum Value Display Maximum Value - Display Minimum Value - (m x Register Minimum Value)

b =

The scaling formula for an entered valued is:

Where:

m =

Entry Maximum Value - Entry Minimum Value Register Minimum Value - Entry Minimum Value - (m x Entry Minimum Value)

b =

Scaling Example:

300 - (-100)

m =

4,095 - 0

= 0.0977

b = -100 - (0.0977 x 0) = -100

Displayed Value = 0.0977 x 2,047 + (-100)

= 99.9919 = 100

Designing Microview Applications 3-7

Description of Example Application

Pump/Tank Levels

When Pump/Tank Levels is selected from the Main Menu, a Sub-Menu displays two new choices (East Pump/Tank and West Pump/Tank). Selecting either of these Sub-Menu items allows you to display pump and tank information for the East or West systems.

Pump Control

Allows you to enter new pump setpoints to be entered. A security code is required to access the Data Entry screens.

Data Entry screens use data from the controller (% Full & CFM) to display this information along with a prompt to enter a new setpoint. When a new setpoint is entered, the value is checked to verify that it is within the programmed limits. If the value is within the entry limits, the number is then scaled to engineering units and sent to the controller. If the value is outside the limits, an error message informs you of the valid range. You can then enter another value.

Appendix B contains worksheets for designing both MicroView applications. Both application layout and screen design worksheets are provided.

Menu Screens

This chapter describes how to create the main menu and sub–menu screens.

Section Page

Menu Screens 6-1 Building a Menu 6-2 Main Menu and Sub-Menu Screen Builder 6-3 Creating a Menu Screen 6-4

Menu Screens provide easy access to different parts of an application. Menus structure an application on the basis of specific tasks and responsibilities.

Each menu screen may consist of up to 8 different menu items. When selected (by pressing a corresponding numeric key), a menu item displays the linked screen or sub-menu.

A typical menu screen might look like this:

1. TEMP.

2. MONITOR

3. LEVEL

Main Menu Screens

Sub-Menu Screens

1 Publication 2707-PM002B-EN-P

The Main Menu is always operator screen #1. This menu lists the primary components of your application. All other menus and data screens are accessed from this screen.

There are two differences between the main menu and sub-menus:

• The MicroView [MENU] key displays the Main Menu. This key is

active at all times.

• The Main Menu is the first screen that appears after a restart or

reset.

Sub-menu screens are identical in appearance to the main menu screen. Sub-menu screens enable you to expand the scope of an application by providing directed choices through linked menus. This allows you to construct a large application and maintain efficient access to specific areas.

6-2 Creating Menu and Sub-Menu Screens

Building a Menu

When you build a menu, you are directing the operator to more specific screens. A menu is a numbered list of components available at the current stage of a process. Number each successive menu entry sequentially. The number tells the operator which MicroView keypad key ([1] through [8]) to press for each menu item (1 through 8).

The following example shows the menu structure of a MicroView application. The operator uses the MicroView numeric keypad keys to select a menu item. Pressing [1] on the keypad selects the Pump Status screen. Screen #11 is linked to keypad key [1] on the MicroView while this menu is displayed. Pressing keypad key [2] on the MicroView displays another menu which has different links assigned to keypad keys [1] and [2].

Main Menu

1. Pump Status

2. Tank Information

Screen 11

Data Displays

This chapter describes how to create data display screens.

Section Page

Data Displays 7-1 Scaling 7-1 Data Display Screen Builder 7-2 Creating a Display Screen 7-3 Display Register Format Selections 7-6

Data display screens allow you to monitor the value of registers in the controller. The MicroView continuously reads the registers to update (at a user-defined rate) the displayed values.

This is how a data display screen may appear:

Tank #1 = 33 Gal 10% Full

To construct data display screens, you need to specify:

• The type of screen as data display

• The type of data stored in the controller register

• The register to access (address)

• Any data format and display information

• The display position for the data

• Any additional text information that you want to display

Scaling

1 Publication 2707-PM002B-EN-P

Data in controller data files can be scaled to standard engineering units such as gallons, pounds, feet, etc. Data is scaled by setting up a proportion between the controller register data limits and the MicroView data display limits. Refer to the description of scaling in Chapter 3.

Data Entry Field

To construct data entry screens, you need to specify:

• The type of screen as data entry

• Any additional text information that you want to display

• The type of data stored in the controller register

• The register to access (address), and if used, a display register

• Any data format and display information

• The display position for the entry field

Scaling

1 Publication 2707-PM002B-EN-P

Data entered in standard engineering units such as gallons, pounds, feet, etc. can be scaled to machine control values. Data is scaled by setting up a proportion between the MicroView data entry limits and the controller register data limits. Refer to the description of scaling in Chapter 3.

IMPORTANT

The 16 bit data format cannot be scaled.

Recipe Screens allow an operator to download a block of data for up to 10 register addresses. These addresses can be in any order. Multiple recipe screens may be linked together in sequential order to download more than 10 register addresses, or to download more than one data format. You can choose to initiate the download automatically or manually (with a prompt).

If recipe screens are linked together, successive screens linked to the first recipe screen are downloaded immediately following the first screen. The operator prompt enabled for the first screen prompts the operator to acknowledge the recipe download. If the other linked recipes do not have the operator prompt enabled they are sent automatically. This appears to the operator as though all recipes were sent as one large recipe.

After you have developed all of the screens necessary for an application, you need to decide how to link them. It is very helpful to create a flowchart of the screens to use as a map before you begin to define the links.

The [PREV] and [NEXT] keys of the MicroView use the linking information to move between screens. Not all links need to have a “next” and “previous” screen. A screen link may create a two-way or one-way relationship.

Two-way links utilize a Link function:

[PREV] selected

One-way links only use a Goto function:

Screen Linking Guidelines

Menu and sub-menu links provide one way links with up to 8 application screens or sub-menus. An operator selects a menu item by pressing the numeric key corresponding to the menu item. When you link the main menu and sub-menu items you are linking screens to the keys on the numeric keypad.

1. Menu 3. Level

2. Temperature

Tank Level 33 Gallons

Temperature is 55 C.

1. Pump Control

2. Pump Output

The following rules apply to linking screens:

• Only screens that are already defined can be linked.

• Wait until you have developed all of your screens and menus

before establishing links. It is much easier to create your links once, rather than change them whenever you change the order of screens.

• A non-menu screen cannot be linked back to a menu screen,

use a Goto (one way) link instead.

• A link is a one-to-one relationship between the current screen

and the target screen. You cannot establish more than a single one-way link to any particular screen.

Publication 2707-PM002B-EN-P

If you attempt to link to a destination screen that is already linked, you have the option of inserting the screen (changing the current link) or aborting the operation.

register that will be used as an acknowledgement bit. If a bit type address was assigned for the write register, this field will be filled in using the bit address specified. ACK/ NAK bits are used only to indicate that the MicroView has received a message.

When set to 1, a value of 1 for the ACK bit indicates a valid screen and a value of 1 for the NAK bit indicates an invalid number. When set to 0, a value of 0 for the ACK bit indicates a valid screen and a value of 0 for the NAK bit indicates an invalid number.

When enabled, the MicroView writes the current screen number to the controller.

The controller address that is written by the MicroView when screen write is enabled. The MicroView writes the current screen number in this register.

Publication 2707-PM002B-EN-P

Entering MicroView Configuration Data 12-5

Advisor Operation

The following shows how the Advisor function operates. The controller program must reset the ACK and NAK bits after writing a screen number.

1. MicroLogix Controller writes screen number to assigned Read Register.

4. Controller monitoring ACK bit

clears ACK/NAK bits for next screen number.

3. MicroView writes Advisor Write Register ACK bit indicating that the screen display was changed. Or wrties NAK bit if an invalid screen was read.

2. MicroView reads Advisor Read Register and displays corresponding screen (if valid).

If the controller sends an invalid screen number (not a programmed screen) the MicroView writes the write register NAK bit (always next sequential bit following ACK bit). The NAK bit indicates to the controller that the screen number is incorrect. The master security code is used by an operator to access and/or change the security codes of the security screens.

Setting Master Security Code

When you select Master Code from the Configuration - Option Selection menu, the following is displayed:

Enter a new security code. There are two codes that perform special functions:

• 00000000 disables the security function. This allows an

operator to enter any number as a valid access code.

• 99999999 disables the master security code(s). When used,

only the security code(s) assigned to individual screens are valid. Use this code when you do not want to provide an operator the ability to override or change security codes for security screens.

The security code must be an 8 digit number, if you enter less than 8 digits, the remaining values are set to 0. The operator must enter all eight numbers (including zeroes) for a valid code.

To save the new security code, press [Esc]. You are returned to the Configuration - Option Selection menu.

ATTENTION

Keep a record of the Master Security Code. If you or another user does not remember the Master Security Code, the unit is disabled. You must return the unit to the factory for repair.

Function Key Options 13-1 Bit Write Mode 13-3 Function Key Builder 13-4 Linking Screens to Function Keys 13-5 Assigning Bit Write Functions 13-6

You can link the MicroView function keys, F1 and F2, to the following screens depending upon whether or not Auto Return is enabled.

Auto Return Enabled? Function keys can be assigned to these screens:

Yes Data Display, Data Entry, Recipe

No Menu, Sub-Menu, Data Display, Data Entry, Security,

Recipe

Pressing an assigned function key displays the function key number for approximately 0.5 seconds and then the assigned screen. There are two function key modes:

• Auto Return

• Continue

Auto Return

Auto return function keys return to the initial display after the linked screen is executed. For example, assume that an application is displaying screen #6 and an auto return function key F2 is linked to a recipe screen #10. When F2 is pressed, the recipe screen #10 is displayed. After the operator downloads a new recipe on screen #10, the initial screen #6 will be again displayed.

The following table describes when the return to the initial screen occurs.

Function Key Linked To: Returns to Initial Screen After:

Data Display Screen

Data Entry Screen A value is entered or

Recipe Screen Recipe data is downloaded or

* [PREV] and [NEXT] abort the operation.

[ ], [PREV] or [NEXT] keys are pressed

[PREV] or [NEXT] keys are pressed *

[PREV], or [NEXT] keys are pressed *

Continue

Continue function keys do not return to the initial display but remain at the linked screen. For example, assume that an application is displaying screen #3 and a continue function key F1 is linked to a data entry screen #5. When F1 is pressed, the data entry screen #5 is displayed. The application continues from screen #5.

Bit Write Mode

The function keys of the MicroView can also set or clear bits in the logic controller. The bit write mode may be enabled with or without screen links being assigned to the same function keys (if bit write is enabled, both function keys will write to the corresponding registers). The function keys are assigned to 2 contiguous 16 bit addresses such as N7:20 and N7:21.

Depending upon how a bit write is configured (clear or set), a function key will either:

• send the corresponding value (F1 = 1, F2 = 2)

• clear the register

The following chart shows the set and clear values for each function key. The register location for F1 is specified on the Function Key Builder screen. The remaining function key is automatically assigned to the next consecutive register.

MicroView Function Key

F1 00000000 00000001 00000000 00000000 1

Set Value Clear Value

F2 00000000 00000010 00000000 00000000 2

TIP

The entire word register (16 bits) is written when a bit write is initiated. Bit write does not change individual bits.

If a function key is used for bit write mode as well as screen navigation, the bit pattern will not be written if the MicroView cannot go to the mapped screen.
