3. Digital CPX output modules
Module parameters: Behaviour 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.
Behaviour after short circuit/overload
Bit Description
1 Short circuit/overload at the outputs (SCO)
Values 0 = V
1 = V
Note With the setting V
reset before the power can be restored. Check which setting is necessary for
reliable operation of your system.
Detailed description under Diagnosis, Tab. 3/23.
Tab. 3/19: Behaviour 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 bus node).
Description Fault mode channel x: Hold last state
Fault state channel x: Set output
Note With the aid of the so−called Fail safe parameterizing, 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).
