I/O Diagnostics Interface

The system CPX-E provides an I/O diagnostic interface in the form of 16 input bits and 16 output bits
for reading detailed diagnostic information. The I/O diagnostic interface can be used, for example, to
precisely determine the module and channel on which an error has occurred. In order to make use of
the I/O diagnostic interface, the bus module of the system CPX-E must be configured accordingly.
The I/O diagnostic interface is shown in the process image if this has been specified by selecting the
catalogue entry „E-PN [STI]" in the hardware configurator.
You can find detailed information about the I/O diagnostic interface in the "Description of system CPX-
E" è 1.1 Applicable Documents.

Diagnostics via PROFINET IO

The system CPX-E supports diagnostics options via PROFINET IO in accordance with IEC 61158; for
example, module-related and channel-related status information as well as error detection in the
online mode of the control software and in the PLC user program.

Error Numbers

With the exception of the CPX-E error numbers listed in è Tab. 12, the CPX-E error numbers in the
PROFINET IO network are transferred with an offset of 1000:
