OptiMate® OM620
Module with Dark Gray Enclosure

The OM620 Operator Terminal is a low cost/high performance man/machine interface with a broad range of operator input and display capabilities. The terminal includes a 2 line by 20 character LCD display, five function keys, and menu tree capability.

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. Messages can also be configured into a layered menu tree, which allows you the ability to create hierarchical function selection for the operator.

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 OM620 Operator Terminal is part of Optimation's OptiMate® series. Each OptiMate® module is designed to connect to a microprocessor or to 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 LCD display as well as to 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 OM620 takes care of the rest.

Operational Overview
The OM620 Terminal incorporates all of the basic elements necessary for operator interface. Function keys allow operator function selection, and the alphanumeric display provides text information and adjustment. Together, the alphanumeric display and associated pushbuttons also allow for user-defined menu tree selection of functions.

The OM620 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 9 PLC registers. Everything else is handled by the OM620 Terminal.

PLC Based Systems
PLC-based systems access the OM620 via a bank of 9 registers. Buttons appear as coils and contacts (or register bits) in the PLC. Messages can be predefined, stored in the OM620 and used by the PLC program. To use a predefined message, your PLC program simply places the message number that you have associated with the message into a PLC register. Text, data display, and arrow adjustment messages are all available. Up to 160 messages can be predefined.

Data adjustment works similarly, with data ending up in the PLC data register. The OM620 allows up to four levels of menu. Each menu selection can be either a function or the next lower menu level. With this type of "tree" arrangement, you can construct an application menu that allows the user quick easy access to a large number of functions.

Use With a Computer
The OM620 Terminal provides all of the same capabilities to a computer-based system that it does to PLC systems. The OptiMate® Hex protocol makes computer-based applications a very simple undertaking. Message numbers and display data are sent to the OM620 over a serial link. Button status and numerical adjustment can be read back from the OM620 by the same serial link.
