Access to these module parameters is made via protocol−specific functions
(see the manual for the field bus node).
Description
With the aid of the so−called Fail safe parametrizing, you can specify the signal
status which the outputs are to assume in the event of field bus communication
faults (see also CPX system manual). This can be accomplished with the follow
ing parameters:
Fault mode channel x
Fault state channel x
Values
Fault mode channel x:
0 = Hold last state
1 = Fault state (presetting)
Fault state channel x:
0 = Reset value (presetting)
1 = Set value
Remark
The parametrizing of the fault mode for an analogue output channel depends on
the field bus protocol and is carried out:
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 Hold last
state" or Fault state".
For parametrizing the Fault state, the desired output word must be correspon
dingly mapped in the parameter bits Fault state channel x".
The Fail safe reaction is determined for the complete CPX terminal by means of
the system parameter Fail safe" (see CPX system manual).
