4.5.3 Fault treatment and parameterizing
The following diagram shows the error treatment of the multi
I/O modules. Further registering and display of the faults can
be suppressed as desired with the appropriate module para
meters, represented in the diagram as switches. The para
meters are described in section 4.4.
