System parameters Brief description
Diagnostic monitoring with:
 Short circuit/overload
 Undervoltage of outputs
 Undervoltage of valve supply
The monitoring of short circuit and overload for the complete CPX
terminal can be switched on or off with this parameter.
Signal status when there is
afault
(Fail−safe parameter)
Defines the status which digital output signals (outputs and
valves) are to assume in the event of field bus communication
faults.
Signal status in Idle mode Defines the status which digital output signals (outputs and
valves) are to assume when changing into the Idle status. This
function is only relevant with certain fieldbus protocols
(see manual for specific CPX bus node).
Force signal status
(force parameter)
Enables the manipulation of signal states separate from actual
operating conditions and independent of the higher−order PLC/IPC.
System start Determines the start−up behaviour of the CPX terminal

Brief description
Diagnostic monitoring with:
 Short circuit/overload
 Undervoltage
 Wire break
The monitoring of short circuit/overload and undervoltage on the
module can be switched on or off with this parameter.
Reaction after:
 Short circuit/overload
 Wire break
Determines after a short circuit/overload or wire fracture whether
the power is to remain switched off or whether it is to be switched
on again automatically.
Input debounce time Serves for trouble−free recognition of digital input signals
Signal stretching time Serves for recognising short signals
Data format of analogue values See manual for the relevant analogue module
