The OM440 Display Panel is a low cost/high performance man/machine interface with a broad range of display capabilities. The panel includes a 4 line by 20 character LCD display and the capability to display BCD, BCD Double, Binary, and Floating Point numbers.

OptiMate® configuration software allows you to predefine up to 160 messages. These messages can be later selected for display by your PLC or computer program to display status.

The OM440 Display Panel is part of Optimation's OptiMate® series. Each OptiMate® module is designed to connect to most PLC's with a single cable connection. OptiMate® 400 series panels can be used individually, with a PLC or in a microprocessor system.

When used with a microprocessor system, simple communications over an RS232 communications cable allows the microprocessor to directly control the LCD display. When used with a PLC, operation is transparent to the user. Terminal functions tie directly into your PLC ladder logic program. The OM440 takes care of the rest.

Operational Overview
The OM440 Panel incorporates all of the basic elements necessary for simple display operation . The alphanumeric display allows the user to display text and/or data display messages. The configuration editor software allows easy configuration of each message.

The OM440 interfaces over an RS232 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 a PLC-based system, operation is totally controlled through a bank of 12 PLC registers. Everything else is handled by the OM440 terminal.

PLC Based Systems
PLC-based systems access the OM440 via a bank of 12 registers. Messages can be predefined, stored in the OM440 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 and data display 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 OM440 takes care of the rest.

Use with a Computer
The OM440 Panel provides all of the same capabilities to a computer-based system that it does to a PLC system. The OptiMate® Hex protocol makes computer-based applications a very simple undertaking. Message numbers and display data are sent to the OM440 over a serial link. Also, in addition to the 160 predefined messages, additional messages with embedded data can be sent to the OM440 via the serial link.
