Festo P.BE−CPX−SYS−EN en 0902e
System parameters Settings Description
Fail safe Reset outputs
(presetting)
Reset all outputs/valves
Hold last state Retain current signal status for all outputs/
valves
Assume Fault mode
value
Accept the signal status defined for the relevant
channel
Tab.C/4: System parameter Fail safe"
If Accept fault mode value" is activated, the signal states
defined by module parameter for the relevant channel will
become effective (see Fig.C/8).
