Individual Station Test - Mitsubishi Electric MELSEC iQ-R Series User Manual

Individual station test

When a problem occurs during data communication with a target device, perform an individual station test to check whether or
not there is any problem in the operation of C24.
The individual station test consists of the following two tests:
• Hardware test
• Self-loopback test
Precautions
• To prevent any problems from occurring, set the CPU module in the STOP state during the individual station test.
• When either one of the interfaces needs to be tested, disregard the test result for the other interface.
• Cable removal and reconnection before and after the self-loopback test should be performed with the power to the station
with C24 turned OFF.
• Before starting data communication with the target device after the individual station test, configure the respective setting
and connect the cable by checking the specifications for the functions to be used.
• If an error occurs even though the settings have been configured correctly for C24 through an individual station test, please
consult your local Mitsubishi representative, explaining a detailed description of the problem.
