Diagnosis in PROFINET
4.10 Diagnosis in PROFINET
In PROFINET, critical events (diagnostic messages) are reported acyclically as alarms.
In addition to information as slot-number, subslot-number, channel type etc., the diagnostic telegrams
contain error codes which define the diagnostic event more precisely.
The error codes are interpreted by the PLC-software or respective function block, so that the diagnostic
messages are normally displayed as plain text.
You will find an example of a diagnostic telegram in chapter 9 , under Diagnosetelegramm mit Error-
Code (page 9-19) .
Please read the following sections, for the meaning of the error codes of the BL67-gateway and the
I/O-modules.
