List of Peripheral Faults
The VBG-PB-K30-D-S saves a list of all AS-i slaves which have triggered a pe-
ripheral errors. This list can be sent with the PROFIBUS diagnostic data.
Default: Transmission in the PROFIBUS diagnostic data.
Earth Fault
The VBG-PB-K30-D-S can detect an earth (ground) fault. The information as to
whether there is or is not an earth fault is sent in the diagnostic data.
Default: Transmission in the PROFIBUS diagnostic data.
Double Address
The VBG-PB-K30-D-S detects when there is double addressing. This list can be
sent with the diagnostic data.
Default: Transmission in the PROFIBUS diagnostic data.
Noise and Over voltage
The VBG-PB-K30-D-S analyzes the quality of the AS-i voltage during running.
This assessment can be sent with the diagnostic data.
Default: Not transmitted in the PROFIBUS diagnostic data.
ExtDiag on Configuration Errors
When an AS-i configuration error occurs, the VBG-PB-K30-D-S sets the ExtDiag
flag in its PROFIBUS data reply. By setting this flag the Profibus DP slave tells the
PROFIBUS master that there is an error condition and that the diagnostic data
are being updated.
In the case of the S7 controller invoking of the OB82 is triggered when an ExtDiag
flag is set. If the latter is not present, the controller is stopped.
Setting this ExtDiag flag can be suppressed using this parameter. Consequently
no interrupt controlled OB82 invoking is triggered in the controller, and the con-
troller must then respond to a possible AS-i configuration error by checking the
AS-i flag in the input data.
Default: Setting of the ExtDiag flag for AS-i configuration error is enabled.
ExtDiag on AS-i Power Fail
Activates and deactivates setting of the ExtDiag flag on AS-i power fail.
Default: Setting of the ExtDiag flag on AS-i power fail is enabled.
ExtDiag on Peripheral Faults
Activates and deactivates setting of the ExtDiag flag on peripheral faults.
Default: Setting of the ExtDiag flag on peripheral faults disabled.
ExtDiag on Earth Fault
Activates and deactivates setting of the ExtDiag flag on earth (ground) fault.
Default: Setting of the ExtDiag flag on earth fault is disabled.
ExtDiag on Double Address
Activates and deactivates setting of the ExtDiag flag on double address.
