|
eType |
Unique ID of the fieldbus type (e.g. CANopen, ProfiBus) |
|
|
idSystem |
CAA.IDENT |
Unique system ID for the identification of the fieldbus. The interpretation of this value is fieldbus dependent (e.g. NetID for CANBus). If the value gc_idMAX_IDENT is returned the system ID could not be determined. |
|
idInstance |
CAA.IDENT |
Instance number in I/O configuration. |
