• "Failed" is displayed for the number of error frames.
If a certain number of error frames is detected for more than one port, start finding error locations
from the port with the highest number of error frames.

nection. Refer to the network configuration diagram to find error locations.
This section explains how to find error locations with two examples of EtherCAT network configura-
tions in which the EtherCAT slave connection configurations are different.
