OptiMate® OM440
Module with Dark Gray Enclosure
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.
PCL-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.
