Default: Transmission in the PROFIBUS diagnostic data.
List of Peripheral Faults
The AS-i/DP Gateway saves a list of all AS-i slaves which have triggered a periph-
eral errors. This list can be sent with the PROFIBUS diagnostic data.
Default: Transmission in the PROFIBUS diagnostic data.
Earth Fault
The AS-i/DP-Gateway 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 AS-i/DP-Gateway 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 AS-i/DP-Gateway 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 AS-i/DP-Gateway 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 control-
ler 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.
Subject to reasonable modifications due to technical advances.
