OptiMate® OM1500
Operator Terminal

OptiMate® configuration software allows you to predefine up to 160 messages. These messages can be later selected by your PLC or computer program to display status, variable data, and allow numeric data input. For computer applications, additional messages can be sent directly over the serial communication port.

Indicator lights and function keys can be custom labeled by the user with a plastic insert. The insert can be custom legended with text and/or graphics, and slipped into a protective pocket behind the faceplate.

The OM1500 Operator Terminal is part of Optimation's OptiMate® series. Each OptiMate® module is designed to connect to a microprocessor or most PLC's with a single cable connection. OptiMate® modules can be used individually, or together with any combination of other OptiMate® modules.

When used with a microprocessor system, simple communications over either an RS232 or RS422 communications cable allows the microprocessor to directly control the lights and LCD display as well as read numeric data entry and function key status.

When used with a PLC, operation is transparent to the user. Terminal functions tie directly into your PLC ladder logic program. The OM1500 takes care of the rest.

Operational Overview
The OM1500 terminal incorporates all of the basic elements necessary for operator interface. Indicator lights highlight status, function keys allow operator function selection, the alphanumeric display provides text information, and the numeric keypad allows data entry and adjustment.

The OM1500 interfaces over either an RS232 or RS422 serial link to any computer-based system and many popular PLCs. In a computer-based system, interface occurs via a very easy to use OptiMate® Hex protocol. For PLC-based system, operation is totally controlled through a bank of 8 PLC registers. Everything else is handled by the OM1500 terminal.

PLC-Based Systems
PLC-based systems access the OM1500 via a bank of 8 registers. Lights and buttons appear as coils and contacts (or register bits) in the PLC. Messages can be predefined, stored in the OM1500 and used by the PLC program. To use a predefined message, the PLC simply places the message number that you have associated with the message into a PLC register. Text, data display, keypad data entry and arrow adjustment messages are all available. Up to 160 messages can be predefined.

There are three types of messages that handle numeric values. A data display message will display the value you place in the line's data register in the message field that has been predefined. The top display line on the right illustrates a data display message. The message has been predefined as message # 6. The carets(^) in the message are place holders for the numeric display. To use the message to display data, simply place the value '6' in the top line message select register and the value (in this case, 347.6) in the top line data register. The OM1500 takes care of the rest.

Data entry and adjustment work similarly, with data ending up in the PLC data register.

Microprocessor-Based Systems
OptiMate® modules connect to any computer or microprocessor-based system through a serial link. Either RS232 or RS422 communications can be employed. The microprocessor controller simply polls for module data or sends module commands to completely control the operator panels.

A legend transparency can be created by a number of methods. Computer graphics programs combined with overhead transparency paper and a laser printer and/or copier produce excellent results. Other options are listed in the OM1124 data sheet.

Use with a Computer
The OM1500 terminal provides all of the same capabilities to a computer-based system that it does to PLC systems. It also provides the added capability to utilize additional messages that are not predefined, but passed over the serial link. The OptiMate® Hex protocol makes computer-based applications a very simple undertaking.
