UINT16 ChannelNumber:
If the interrupt relates to a specific channel of the IO device (e.g. short circuit),
this parameter must contain the number of the faulty channel.
If the interrupt was generated by a module or submodule, the number of the
channel must be set to 0x8000.
•
UINT16 ErrorType:
The parameter defines error types according to PROFINET standard, see "Er-
ror types" section.
•
EDiagSeverity Severity:
The value of the severity for the diagnostics, see EDiagSeverity (Page 346).
•
EDiagProperty Direction:
The value for the incoming/outgoing information, see EDiagProperty
(Page 345).
•
UINT16 ExtErrorType:
This parameter provides the option of defining more details for the diagnostic
interrupt. This is helpful in combination with PDEV error types which are gener-
ated for CPU-internal modules. Should be 0 by default.
