11.3 Diagnostic data
The IO device sends an alarm message to the IO controller to signalise the diagnostic
data below.
Code C13887
serves to inhibit the transmission of alarm messages to the IO controller.
By this, errors of a specific type can be systematically suppressed.
Errors and warnings in the Inverter Drive 8400 and the plugged-in module are sent to
the IO controller as extended diagnostic messages.
The diagnostic data can be displayed using the hexadecimal representation of the
Siemens S7 engineering tool.
