Tab. 4/16: Overview of status bits - Part 2
If various errors occur simultaneously on different types of
modules, these errors cannot be assigned via the status bits.
Errors may be uniquely determined through the I/O dia-
gnostics interface or diagnostics via EtherNet/IP access.
Further instructions on the function and content of the status
bits can be found in the CPX system description.
For the bus node CPX-FB36, access to the EtherNet/IP Ob-
jects through Explicit Message programming is in principle
more appropriate than the use of the I/O diagnostic interface
( section C.1).
Detailed diagnostic information can be accessed via the I/O
diagnostic interface. You can ascertain exactly, for example,
on which module and on which channel an error has oc-
curred. System diagnostics are retrieved by means of 16 in-
put bits and 16 output bits, through which all diagnostics
data can be read.
