 Step 3: Finding Locations of Errors with Trends in Slave Diagnostic and
Statistical Information
You can check for trends of values in the slave diagnostic and statistical information to find the loca-
tions of the errors.
Example of the Slave Diagnosis/Statistics Tab Page of Sysmac Studio
The following are the points to check to find error locations based on the number of error frames.
• A certain number of error frames is detected.
• The number of error frames is increased compared to the value acquired last time.
• 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.
The error locations that you find will change depending on the configuration of EtherCAT slave con-
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.
