5. Analogue output module CPX−2AA−U−I
Module parameters: Idle mode 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 Idle mode parametrizing is only relevant with certain field bus protocols.
With the aid of the so−called Idle mode, you can determine the signal status
which the outputs are to assume when the Idle function is accessed (see also
CPX system manual). This can be accomplished with the following parameters:
Values
Remark The parametrizing of the Idle mode for an analogue output channel is accom
plished in the case of the field bus node CPX−FB11 by means of an individual
parameter setting or bit.
For parametrizing the Idle state, the desired output word must be correspon
dingly mapped in the parameter bits Idle state channel x".
The Idle mode reaction is determined for the complete CPX terminal by means of
the system parameter System Idle mode" (see CPX system manual).
