Overview
This guide describes procedures for connecting a Digital Temperature Controller (E5
□
D,
E5
□
C or E5
□
C-T) to an NJ-series Machine Automation Cont Serial Communications
Unit (hereinafter referred to as the "Controller") 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 program in the prepared Sysmac Studio project file is used to check the serial connection
by sending or receiving a message of ''Read Controller Attributes'' to/from the Digital
Temperature Controller.

Hereinafter, the Sysmac Studio project file is referred to as “the project file".
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.
