Tab.3/4: Overview of status bits
If all status bits supply a 0−signal, no fault will be registered.
If various faults occur simultaneously on various types of
modules, they cannot be classified via the status bits. If
necessary, faults can be clearly defined via the I/O diagnostic
interface.
Further instructions on the function and content of the status
bits can be found in the CPX system manual.
