Diagnostic and Statistical Information

The diagnostic and statistical information provides statistics on the number of communications frames
sent and received by the EtherCAT master and EtherCAT slaves as well as the number of frames for
which errors were detected.
You can use it to diagnosis the EtherCAT network line qualify for the following:
• Confirming that the EtherCAT network was correctly installed during a test run
• Finding the causes of communications errors that occur during normal operation
• Checking the EtherCAT network line quality during normal operation
EtherCAT Network Diagnostic Procedure
You can diagnose the EtherCAT network with the diagnostic and statistical information for the master
and slaves. The procedure to diagnose the EtherCAT network is given below.
If the diagnostic results show that the EtherCAT network is not operating normally, you can find the
location of the error.
An outline procedure from EtherCAT network diagnosis through correction is given below.
