16 Fault tracing aids
If a fault is displayed, it is always practical to select operating line Faults > Faults current
and look for any pending fault status messages before starting to rectify faults. In the
event of a faulty extension module, that fault must always be rectified first since it may
lead to consequential fault status messages.
For a detailed description of the display, the acknowledgement and the reset of faults,
refer to chapter 14 "Function block faults".
