Implementation of EtherNet/IP™
D301271 1013 - FGEN - multi protocol7-36
7.5 Diagnostic messages via process data
Besides the evaluation of diagnostic data via Explicit Messages, FGEN with EtherNet/IP™ offers the
possibility of mapping diagnostic data into the process data (see also the stations‘ process data
mappings (page 7-11 ff.).
2 different forms of diagnostic data handling are provided:
summarized diagnostics
Scheduled Diagnostics
7.5.1 Summarized Diagnostics
If the summarized diagnostic data mode is activated, 1 bit indicates that at least one of the station
channels sends a diagnosis.
This bit will be "0" if there are no diagnostic flags set on the device. If there are any diagnostic events on
the device, the bit will be set to "1".
Bit „I/O Diag“
0 = OK, no diagnostics present
1 = at least one channel sends diagnostics
7.5.2 Scheduled Diagnostics (manufacturer specific diagnosis)
In FGEN-stations, the scheduled diagnostics feature (Process Data Class (VSC102) (page 7-31)) is used
for mapping the channel diagnostic bits into the process data (see also the modules‘ process data
mappings (page 7-11 ff.).
Bit „SchedDiag“
0 = no mapping of I/O-channel diagnostics to process data
1 = mapping of I/O-channel diagnostics to the process input data active
