What is the state of Tesys Island after a communication loss?
Product Line:
Motor Management system Tesys Island
Environment:
IEC Contactors and Starters
Resolution:
When fieldbus communication with the controller is lost, TeSys island remains in the operational state however, enters Degraded mode. Communication loss is defined by:
• EtherNet/IP fieldbus: Communication loss is detected when an established exclusive owner connection times out. NOTE: If the PLC enters an idle state for an established exclusive connection, the TeSys island will run in normal condition.
• Modbus/TCP fieldbus: Communication loss is detected after receiving no write requests to the cyclic I/O scanning data for the duration specified by the Communication Loss Timeout setting in the DTM.
• PROFINET fieldbus: Communication loss is detected when an established application relation (AR) with an I/O controller is closed or disconnected on either end of the AR. TeSys island supports one AR per I/O controller.
• PROFIBUS-DP fieldbus: Communication loss is detected when the watchdog timer for the connection expires.
NOTE: Loss of communication with the DTM or OMT does not trigger the transition to Degraded mode.
During Degraded mode:
• The Fieldbus ports remains active.
• The Service port remains active.
• The TeSys avatars enter Degraded mode. During Degraded mode, avatars with local control are driven by local inputs. All other avatars enter Fallback state.
