3.4 Diagnosis via I/O diagnostic interface
For the fieldbus node CPX-FB32,access to the EtherNet/IP
Objects through Explicit Message programming is in principle
more appropriate than the use of the I/O diagnostic interface
(see Appendix B.1).
Detailed diagnostic information can be accessed via the I/O
diagnostic i nterface. You can ascertain exactly, for example,
on which module and on which channel an error has
occurred. 16 input bits and 16 output bits, through which all
diagnostic data can be read, are available for accessing the
system diagnosis.
Note
In order to use the I/O diagnostic interface, it must be
activated with the DI L switch on the fieldbus node
(see Tab. 1/2).
If the I/O diagnostic interface is active, it will occupy the first
16 inputs and outputs in the address range (see Tab. 2/7).
Information on the I/O diagnostic interface (diagnostic
information, function numbers) can be found in the CPX
system description.
