Behavior in case of a communication interruption: Watchdog

If the communication between the PLC and the analog outputs is interrupted, the analog outputs no longer receive any preset values.
Watchdogs monitor the communication and can take over control of the analog outputs if the communication is interrupted.

There are two Watchdogs:

• The "SM Watchdog" monitors the EtherCAT communication.
• The "PDI Watchdog" monitors the communication inside the module.

Both Watchdogs are disabled in the factory setting.
