Diagnostics via the I/O diagnostics interface

Festo CPX-FB36-EN en 1611a English
Detailed diagnostic information about the CPX terminal can
be accessed via the I/O diagnostic interface. As a result, it
can be determined exactly on which module and channel an
error has occurred, for example. Available to access this in­
formation are 16 input bits and 16 output bits, through which
all diagnostic data can be read.
To use the I/O diagnostics interface, it must be activated via
DIL switches on the bus node (è Tab. 1/3). If the I/O dia­
gnostic interface is activated, it will occupy the first 16 inputs
and outputs in the address range (è Tab. B/8).

Detailed information on the I/O diagnostic information and
the available diagnostic information and the corresponding
function numbers can be found in the CPX system description
(è P.BE-CPX-SYS-...).
Access to EtherNet/IP objects via Explicit Messaging pro­
gramming makes more sense with the bus node CPX-FB36
than use of the I/O diagnostics interface (è C.1).
