Communication
Supervision
The heartbeat mechanism is used to check if the FactoryTalk View SE Data
Server is still alive. The HMI tag Heartbeat reads a pulse from the
ControlLogix software. The derived tag function HeartbeatFct writes the
status of the Heartbeat tag to the derived tag HeartbeatRet. The
ControlLogix software monitors this tag for timeouts and generates an alarm.
