Communication Channel Testing

Introduction

This topic discusses the different possibilities for testing a communication channel from the debugging screen. Remember:

Available Requests

The X-Way station test window allows the following requests:

Identification: Prompts the Identification request to be sent to the designated remote station.
Mirror: Allows a mirror request to be sent to the designated station. Selecting this function gives access to a screen that allows you to select the length of the character string to be sent (a maximum of 80 characters ). The PLC then sends this character string (ABCD...) to the destination device. This device automatically returns the string of characters received to the sender.
Request input: Allows a UNI-TE request, other than those provided by the command buttons, to be sent to the designated station. If this function is chosen, a screen appears allowing you to select the parameters specific to the request (the request code must be coded in hexadecimal).

NOTE: The first two requests are sent to the UNITE server of the TSX ETY module. The third is sent to the server of the processor.
