2.5.3 Fault treatment and parametrizing
The following diagrams show the fault treatment in the ana
logue input modules. Further registering and display of the
fault can be suppressed as desired with the appropriate
module parameter, represented in the diagram as a switch.
A description of the parameter can be found in section 2.4.3.
