5. Analogue output module CPX−2AA−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 output value (see also CPX system manual). This can be accomplished
with the following parameters:
Values
Remark The enabling of the Force function with the parameter Force mode outputs
channel x" depends on the field bus protocol and is carried out:
For parametrizing the Force state, the desired output word must be correspon
dingly mapped in the parameter bits Force state outputs 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).
Tab. 5/18: Force channel x (channel−specific)
5−26
Force mode outputs channel x
Force state outputs channel x
Force mode outputs channel x:
Force state outputs channel x:
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"
or Force state".
0 = Blocked (presetting)
1 = Force state
0 = Reset value (presetting)
1 = Set value
