The web server can be accessed by entering the IP address in the address bar of a web browser.

Diagnostics via PROFINET IO
The automation system CPX-AP-A supports diagnostic options via PROFINET IO in accordance with
IEC 61158, e.g. module-related and channel-related status information as well as error detection in the
online mode of the control software and in the user program of the high-order controller.
Diagnostic messages from the automation system CPX-AP-A that cannot be seen on the PROFINET
standard diagnostics are shown as manufacturer-specific PROFINET channel diagnostics.
For PROFINET, only the lower 16 bits of the diagnostics ID (error number) are shown.
The display rule is as follows:
–
Error number 1 … 32767:
ChannelErrType = 2001 with ExtChannelErrType = error number
–
Error number 32768 … 65535:
ChannelErrType = 2002 with ExtChannelErrType = error number – 32768
The error number 0 is reserved.
