The definitions in the GSD file (GSD =

escription) enable easy access to the device
parameters if this is supported by the configuration tool of the Profibus DP master:
Example Siemens step 7: Byte 37, bit 5 = TRUE
If the parameter "Extended Profibus Diag." is set to "Enabled", the AS-i master transmits the extended
diagnostic data described in the next section. This data generates a DP request for a diagnosis in
case of an error state in the AS-i master. Therefore a Siemens PLC OB82 must be programmed to
react to this state, otherwise the PLC stops.
For "Disabled" (default) the AS-i master only transmits the standard diagnosis. An AS-i error state has
no direct effect on the Profibus DP but must then be monitored otherwise by the PLC (using the bits
4...7 in the first byte or via the command channel).
Example Siemens step 7: Byte 37, bit 4 = TRUE
