2.5.4 Fault treatment and parametrizing
Depending on the module parametrizing, the faults are sent
to the field bus node, where they can be evaluated according
to the field bus protocol used.
The following diagram show the fault treatment in the MPA
pneumatic modules. Further registering and display of the
faults can be suppressed as desired with the appropriate
module parameters, represented here as switches.
The parameter is described in section 2.4.
