9.5.2.2.2.3 EtherCAT slave: Synchronization – Read out diagnostic parameter

ð A261[0] – [3] shows the state of the EtherCAT synchronization.
3. A261[0]:
Specifies the number of the error code.
4. A261[1]:
Specifies the time difference between the data provision and the Sync 0 signal in µs.
5. A261[2]:
If the process data from the master arrived at the slave after the Sync0 signal in the slave, or if the time difference
between process data receipt and Sync0 signal is greater than half of A150, A261[2] is incremented.
