7.3 Watchdog
behaviour
For all
ecomat
mobile
controllers the program runtime is monitored by a watchdog. If the maximum
watchdog time is exceeded, the controller carries out a reset and starts again (SafetyController:
controller remains in the reset; LED goes out).
Depending on the hardware the individual controllers have a different time behaviour:
Controller
