With the function Set_Prm you have the possibility of deter-
mining the watchdog time (WD_Fact_1, Octet 2, WD_Fact_2,
Octet 3). In the event of a fault, e.g. a bus failure, the CP sys-
tem will switch off all the valves and electric outputs after the
parametrized time.
With these controllers you can determine the reaction of the
CP system to the faults mentioned (details see controller
manual).
Almost all configuration programs contain the function
"Response monitoring". For the operating modes mentioned,
the time specified corresponds to the drop-off time of the
valves and electric outputs.
Further details on response monitoring can be found in the
appropriate manuals.
