2.5 D ia g n o s t i c s
Specific faults of the input modules are registered or
suppressed depending on the module parameterization.
The faults are shown on−the−spot by means of the Error LED
and, if necessary, can be evaluated with the handheld (MMI).
Depending on the module parameterizing, the faults are sent
to the bus node, where they can be evaluated according to
the field bus protocol used.
2.5.1 Fault messages of the input modules
An input module can register the following standard faults:
