5.2 Diagnosis via status bits or the I/O diagnostic interface
The CPX terminal offers the following two modes for diagĆ
nosis, irrespective of the CPX bus node used:
Mode Description
Status bits
(system status) The status bits serve for displaying comĆ
mon diagnostic messages (global fault
message). Access to the status bits is
made via 8 internal inputs (see section
5.2.1).
I/O diagnostic interĆ
face (system diagnoĆ
sis) The I/O diagnostic interface is a fieldbus−
independent diagnostic interface.
With this interface, all internal data and
parameters can be read out via 16 internal
inputs and 16 internal outputs (see secĆ
tion 5.2.2 and Appendix B). All diagnostic
information is then also available even if
the fieldbus protocol used does not offer
any extensive diagnostic functions.
