12.4 Error counters of the EtherCAT slaves

The EtherCAT slaves have numerical error counters for detecting and analysing error states. All error

counters have a limited counting range of 0 ... 255. After the maximum value of 255 is reached, no

"wrap-around" takes place. If the PLC application is to make a sensible evaluation of the error

counters, these must be deleted by the application after the evaluation via a write access.

12.4.1 Error types "Errors" and "Forwarded Errors"

The EtherCAT slaves differ between errors detected in the slave for the first time (red error) and

forwarded errors, i.e. errors that have already been detected in a previous slave (green error).

When the corresponding error counters are evaluated, an error in the EtherCAT network can be

clearly assigned to a bus segment or a slave.
