The ABB control uses “data sets” to exchange information with the drives (CH0).

Every data set consists of three 16-bit Integer values (indices). A data set number and the data set index provide a given measurement or status value with ABB.



The ABB controller sends even data set numbers (2n) to the drives, which respond with the next odd data set number (2n + 1).

The desired signals are selected with ibaPDA via the following parameters

  • Node number (drive)

  • Data Set number

  • Index

The ibaBM-DDCS device can read all data sets that the controller requests from and sends to the drives.
