Diagnosis via I/O diagnostic interface

3−14
Further instructions on the function and contents of the
status bits can be found in the CPX system manual.
Detailed diagnostic information can be accessed via the I/O
diagnostic interface. You can ascertain exactly, e.g. on which
module and in which channel a fault has occurred. The sys
tem diagnosis can be accessed by means of 16 input bits and
16 output bits, with which all diagnostic data can be read out.
For the field bus node CPX−FB11, access to the DeviceNet
objects with Explicit Message programming is always more
suitable than via the I/O diagnostic interface (see section
A.3).
Information on the available diagnostic information and its
function numbers can be found in the CPX system manual.
Please note
In order to use the I/O diagnostic interface, you must acti
vate it with the DIL switches on the field bus node.
If the I/O diagnostic interface is active, it will occupy the first
16 inputs and outputs in the address range.
Instructions on diagnosing with the I/O diagnostic interface
can be found in the CPX system manual.
