2. Analogue input module CPX-2AE-U-I
Module parameters: Force channel x
Function no. Access to these module parameters is made via protocol-specific functions
(see the manual for the field bus node).
Description The Force function permits the manipulation of analogue values irrespective of
the actual input value (see also CPX system manual). This can be accomplished
with the following parameters:
– Force mode inputs channel x
– Force state inputs channel x
Values – Force mode inputs channel x
– Force state inputs channel x
Comment The enabling of the Force function with the parameter "Force mode inputs
channel x" depends on the field bus protocol and is accomplished:
– by an individual parameter setting or bit (e.g. CPX-FB11),
– by setting all parameter bits of the relevant word (e.g. CPX-FB6) to "blocked"
For parameterisation of the Force state, the desired input word must be
correspondingly mapped in the parameter bits "Force state inputs channel x".
The enabling of the Force function for the complete CPX terminal is made by
means of the system parameter "Force mode" (see CPX system manual).

or "Force state".
0 = blocked (presetting)
1 = Force state
0 = reset value (presetting)
1 = set value
