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.
