Diagnostic Messages via the Process Data
Besides the evaluation of diagnostic data via Explicit Messages, XI/ON for EtherNet/IP offers
the possibility of mapping diagnostic data into the gateways’ process data.
2 different forms of diagnostic data handling are provided:
• Summarized Diagnostics
• Scheduled Diagnostics
Summarized Diagnostics
The summarized diagnostic data mode will send back 1 bit for each slice within the station.
This bit will be "0" if there are no diagnostic flags set on the slice. If there are any diagnostic
events on the slice the bit will be set to "1".
Values:
0 = ok
1 = module sends diagnostics, wrong module or module pulled (acc. to VSC 100, Gateway
Class, Attr. 116, Section „Gateway Class (VSC 100)”, Page 77).
The diagnostic bits are placed at the end of the input data. The diagnostic data start WORD
aligned (see Section „Mapping of process data”, Page 64).
Scheduled Diagnostics
The scheduled diagnostic data map is a time sliced module related data block, which holds
diagnostic data of all modules with active diagnostics using a round robin mechanism.
This diagnostic "window" visualizes a specific module diagnostic data for approx. 125 ms and
changes over to the next active diagnostics afterwards. This is done automatically by the
gateway.
The data length for the scheduled diagnostics is set according to properties of the modules
attached to the gateway.
The scheduled diagnostic data is placed at the end of the input data and after the summarized
diagnostic data (see Section „Mapping of process data”, Page 64).
Note
The Scheduled Diagnostics possibility is only implemented in gateways with
