7.4
Parameterization of the diagnostics
In addition to the PROFIBUS / PROFINET standard diagnostics, the RF170C offers user-specific
diagnostics data integrated in the diagnostics of the interface module.
The diagnostics data can be read out as follows:
•
as plain text in the STEP 7 user interface
•
on PROFIBUS DP
–
Read out with SFC 13 slave diagnostics and store in the data area of the application
•
on PROFINET IO
–
Read data records from the IO device with SFB 52
–
Receive alarms from the IO device with SFB 54
•
Evaluation with FB 125 or FC 125
Parameter assignment options
•
None
No other diagnostics data is reported, apart from standard diagnostics.
•
Hard errors
Extended diagnostics messages are generated in the case of the following events.
–
Hardware fault (memory test)
–
Firmware error (checksum)
–
Connection to reader lost
–
Short-circuit fault/interruption, if supported by hardware
–
Firmware update (message at start/end)
In the case of this diagnostics, the “Ext_Diag” bit is set, that is, it is treated as high-priority
diagnostics information in the controller (SF-LED is lit)
