Faults of the CPX−CP interface or the CP module connected
are reported to the CPX field bus node or CPX−FEC as CPX
fault messages. The following sections contain the special
features of the representation for the CPX−specific diagnostic
options.
Status bits (see section 4.4.1)
Diagnostic memory (I/O diagnostic interface,
see section 4.4.2)
Tab. 4/7 shows the effect of the CPX−CP interface on the
