9. Program

This section explains the details on the program in the project file that is used in this document.

9.1. Overview

This section explains the specifications and functions of the program used to check the
connection between the YAMAHA MORTOR Robot Controller (Hereafter, referred to as a
"destination device") and the PLC (using the Ethernet Unit).
This program performs the TCP socket communications by manipulating a dedicated control
bit, sends and receives the message of "Acquire version information" and detects a normal
end or an error end.
A normal end of this program means a normal end of the TCP socket communications.
An error end means an error end of the TCP socket communications and destination device
error (detected with the response data from the destination device).
The keep-alive and linger functions, which are TCP socket options, are not used in this
program. Whether to use them must be determined when configuring the system.
In this section, 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 and "#03E8" for hexadecimal)
Additional Information
OMRON has confirmed that normal communications can be performed using this program
under the OMRON evaluation conditions including the test system configuration, version of
each product, and product Lot, No. of each device which was used for evaluation.
OMRON does not guarantee the normal operation under the disturbance such as electrical
noise and the performance variation of the device.
