2. Digital CPX input modules
Module parameters: Behaviour after short circuit/overload
Function no. 4828 + m * 64 + 1
Description Determines after a short circuit in the sensor supply 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
0 Short circuit/overload in sensor supply (SCS)
Values 0 = V
1 = V
Note With the setting V
restore the power. Check which setting is necessary for reliable operation of your
system.
This parameter applies to the whole module with modules CPX−8DE−D and
CPX−M−16DE−D as well.
Detailed description under Diagnosis, Tab. 2/33.
Tab. 2/28: Behaviour after short circuit/overload
Module parameters: Input debouncing time
Function no. 4828 + m * 64 + 1
Description Determines when a change of edge of the sensor signal on this module is to be
accepted as a logical input signal.
Bit Bits 4, 5
Values Switch−on debounce time
Bit 5 4 Description
0 0 0.1 ms
0 1 3 ms (presetting)
1 0 10 ms
1 1 20 ms
Note Input debouncing times are specified in order to eliminate interfering changes of
signal edge during switching procedures (bouncing of the input signal). This
setting applies to all inputs of the module.
Further information on this parameter can be found in the CPX system manual.
