With these controllers, you can determine the reaction of the
CP system to the faults named above.
Almost all configuration programs contain the function
Response monitoring." For the operating modes named, the
time specified corresponds to the drop−off time of the valves
and electric outputs.
There are two ways in which you can set the control system to
react to faults:
Hard fault reaction: When a fault occurs the controller
switches to the operating mode STOP"
Soft fault reaction: When a fault occurs the controller
remains in the operating mode RUN"
