The image on the left shows a small number (2) of acyclic frames sent by the master during the respective
second - all slaves are operating properly. The image on the right shows a significant increase (currently 77
acyclic frames/sec): The EtherCAT master has quickly detected that not all slaves are properly taking part in
the data exchange. Once the master has located the fault, it continuously tries to restore the connection.
