5. Output modules
Module parameters: Reaction after short circuit/overload
Function no. 4828 + m * 64 + 1
Description Determines after 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
Bit Description
1 Short circuit/overload at the outputs (SCO)
Values 0 = V
1 = V
Remark With the setting V
reset before the power can be restored. Check which setting is necessary for
reliable operation of your machine or system.
Detailed description under Diagnosis", Tab. 5/19.
Tab. 5/15: Reaction after short circuit/overload
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:
Fault state channel x:
Remark 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).
