16.9 Configuring the 'Reporting of System Errors'
Programming with STEP 7
Manual, 05/2010, A5E02789666-01 381
Note
• The station errors (failure/return) are displayed in plain text for all PROFIBUS DP slaves.
• The manufacturer-specific diagnostics is supported for all PROFIBUS DP slaves with the following
restrictions:
- Only V1 slaves are supported. These are slaves with a GSD file containing the entry
"DPV1_Slave=1".
- The DP interrupt mode must be set to "DPV0" for this slave.
Errors that do not occur during operation (CPU in STOP, DP slave failed):
• Station errors are supported
• Module errors are supported
• Channel errors are supported and extended channel error information is evaluated
In STEP 7 the diagnostics message is displayed via the call of the module state in the on-line
window "HW Config" (diagnose hardware) in the "DP Slave Diagnostics" tab card under "Hex
display".
Diagnostic Repeater: The messages of the Diagnostic Repeater are output as plain text in DPV0
mode. The text is read from the GSD file.
PROFIBUS DP over IE/PB Link or IWLAN/PB Link
The PROFIBUS DP master system of an IE/PB link cannot be diagnosed.
• For a PROFIBUS DP master system downstream from an IE/PB link, the status is not updated
in the PROFIBUS data block (DB 125). The diagnostics is partially performed via the
PROFINET IO-DB. In this case, only the status of the slaves (OK, disrupted, failed) in the
PROFINET IO DB is available, not the module and channel errors.
PROFIBUS DP/PA via DP/PA-Link
The following station statuses are detected:
• Station OK (the entire station is working properly)
• Station disrupted (an error occurred on the station, but it is continuing to run)
• Station failed (the entire station has failed)
Note
• You cannot configure the DP/PA Link using a GSD file.
• Diagnostics of a DP/PA Link with a 300 series CPU is not supported.
