Fieldbus control through a fieldbus adapter 433Basics of the fieldbus control interfaceThe cyclic communication between a fieldbus system and the drive consists of 16- or32-bit input and output data words. The drive is able to support a maximum of 12 datawords (16 bits) in each direction.Data transmitted from the drive to the fieldbus controller is defined by parameters52.01 FBA A data in1 … 52.12 FBA A data in12.
