In addition to the DP-compliant diagnostic information, the PCD3.RIO also
supportsadiagnosismoduleusedintheDPconguration.Thisslavediagnostic
information is stored in the master resources. The use of a diagnosis module is
notmandatory.Thisdiagnosticmodulemusthoweverbeconguredafterthelast
I/Omodule(exception:plug-insmustbeconguredafter the diagnosis module).

Reply
The contents of bytes 0 to 2 depend on the request command. The master
always checks if the response command matches the request command,
ensuring that the data is correct and belongs to the requested information.
NOP command (command 0)
This command is for synchronization only. The RIO returns the received data
byteswithoutmodication.
