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.

MicroView application programs are created using MicroView DPS. The development of applications for the MicroView are very similar to the DTAM Micro and DTAM Plus. The differences in application development are related to differences in the operator terminals. The following table lists MicroView Functional considerations.

Screen Types and Data Formats

Some application screens require that you specify register information. Each MicroView screen type supports different data formats. The table below lists each screen type and the data formats supported.

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.

This Value is Displayed:

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

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.

Designing an Application

Use the application design worksheets to layout a logical sequence of screens. Make copies of the worksheets as needed. On each worksheet, list the screen numbers, type of screens, register numbers, etc.

Application Worksheet

Use the screen worksheets to define screen text and layout. Make copies of the screen worksheets and write out each application screen.

RSSUREE

Before you design an application, become familiar with the types of screens and how they function. To assist you, a sample application is provided in this chapter. In addition, you should become familiar with the controller files and data type supported for each operator module type and selected protocol (see previous section). When register information is required, this manual lists the applicable data formats (such as ASCII or 16 Bit Hex) for each controller file type.

Designing Microview Applications 3-9

Recommended sequence for designing an application

1. On paper, design all the operator screens with the associated

2. Construct all screens using DPS. Save the program file without linking.

3. Link the application screens. Use the design from step 1. When you have established all links, save the program file. An error display will warn you of any unlinked screens.

4. Download the application file.

5. Use the Simulate function (described in the MicroView User

Manual) to verify operations such as screen links, text, and screen types.

6. Run the application.
