Program; Overview - Omron E5 D Series Connection Manual

9. Program

This section describes the details on the program used in this guide.

9.1. Overview

The following explains the specifications and functions of the program that are used to check
the connection between the Digital Temperature Controller (hereinafter referred to as the
"Destination Device") and the PLC (Serial Communications Unit (hereinafter referred to as the
"SCU")).
This program uses the protocol macro function of the SCU, to send/receive the "Properties
Read" command to/from the Destination Device and detect a normal end or an error end.
A normal end of the send/receive processing means a normal end of the communications
sequence.
An error end means an error end of the communications sequence and an error of the
Destination Device (identified in the response data from the Destination Device)
Here, the prefix "&" is added to decimal data and the prefix "#" is added to hexadecimal data
when it is necessary to distinguish between decimal and hexadecimal data. (e.g., "&1000" for
decimal data and "#03E8" for hexadecimal data)
Additional Information
OMRON has confirmed that normal communications can be performed using this program
under the conditions of 5.2. Device Configuration. However, we do not guarantee the normal
operation under disturbances such as electrical noise or device performance variation.
