The CP system reacts on the ABB CS31 system bus like a bi-
nary input/output module. All central processing units and
couplers perform the general monitoring of the CS31 system
bus, e.g. in the event of total failure of local modules.
On the CP system the central processing units and couplers
also interrogate the diagnostic messages which are provided
(see section "Diagnostic byte" in this chapter).
Depending on the output ability, the diagnostic messages are
available in detail for further processing and for interrogation
with test units. The displays on the central processing units
and couplers provide a summary of the status of the ABB
CS31 system bus and local modules.
The relevant ABB manuals apply to all central processing
units and couplers. The following table shows as an example
the diagnostic possibilities in conjunction with:
– central processing unit 07KR91
– coupler 07CS61
