Diagnostics
A PROFIBUS network enables a slave to report back to the master
regarding problems on the network.
Diagnostics take place during the normal process of data exchange.
To initiate a diagnostics request, XtraDrive-DP sends an error flag
in the frame control to the master. The master then sends a
diagnostic request that is answered by XtraDrive-DP.
The master can request diagnostic information at different times:
✦ Before downloading parameters, to make sure the field device
✦ Before entering the data exchange mode, to validate parameters
✦ During data exchange, whenever indicated by the field device.
The XtraDrive-DP diagnostic information that is sent to the master
consists of standard PROFIBUS diagnostic information, plus
additional diagnostic information for the XtraDrive-DP: alarms,
warnings, faults and command IDs.
The structure of an XtraDrive-DP diagnostic message is shown in
