Remarks
- The working counter errors are cleared to zero when the EtherCAT network is taken from Init to OP state.
- Value 0 (zero)means no working counter errors.
- When the value is non zero, the master automatically reduces the count by 1 for every thousand good frames received.
- When the working counter error exceeds the Working Counter Error Limit, the EtherCAT network is stopped.
-
- See Check for Working Counter Errors in Example: EtherCAT Communication Diagnosis Steps for an example of implementing this function.
