Overview - Omron E5 D Series Connection Manual

4. Overview

This guide describes procedures for connecting a Digital Temperature Controller (E5□D,
E5□C or E5□C-T) to a CJ-series Programmable Controller + Serial Communications Unit
(hereinafter referred to as the "PLC") via serial communications, both produced by OMRON
Corporation (hereinafter referred to as "OMRON"), and for checking their communication
status.
Refer to Section 6. Serial Communications Settings and Section 7. Serial Communications
Connection Procedure to understand setting methods and key points to send or receive a
message via serial communications.
The ladder program in the prepared CX-Programmer project file is used to check the serial
connection by sending or receiving a message of ''Properties Read'' to/from the Digital
Temperature Controller.

This guide aims to explain wiring methods and communications settings
necessary to connect corresponding devices and provides the setting
procedures. The program used in this guide is not designed to be constantly
used at a site but is designed to check if the connection is properly established.
Both functionalities and performances are therefore not fully considered for the
program.
When you actually construct a system, please use the wiring methods,
communications settings and setting procedures described in this guide as a
reference, and design a program according to your application needs.
