Module parameters: Reaction after short circuit/overload
Function no. 4828 + m * 64 + 1 m = module number (0 ... 47)
Description Determines in the event of a short circuit of the outputs whether the power is to
remain switched off or whether it is to be switched on again automatically.

Reaction after short circuit/overload
Description
Short circuit/overload at the outputs (SCO) [Behaviour after]
[Behaviour after SCO]
Values 0 = V
OUT
remains switched off (presetting)
1 = V
OUT
switch on again
[Leave switched off ]
[Resume]
Note With the setting V
OUT
remains switched off," the relevant output must be set/
reset before the power can be restored. Check which setting is necessary for
reliable operation of your system.

Module parameters: Fail safe channel x
Function no. Access to these module parameters is made via protocol−specific functions
(see the manual for the field bus node).
Description Fault mode channel x: Hold last state
Fault state (presetting)
Fault state channel x: Set output
Reset output (presetting)
Note With the aid of the so−called Fail Safe parametrizing, you can specify the signal
status which the outputs are to assume in the event of field bus communication
faults (see also CPX system manual).
