The Function Block DPV1_MSAC1_WRITE implements the acyclic PROFIBUS DP DPV1 service MSAC1_WRITE. Using this function, the master has write access to slot and index-related data of slaves supporting DPV1. DPV1_MSAC1_WRITE works outside the cyclic process data exchange.
Every time a FALSE → TRUE edge is applied to input EN, DPV1_MSAC1_WRITE reads the values at its inputs and the data to be written and sends a corresponding request message to the Communication Module. Further FALSE → TRUE edges at input EN are ignored until the processing of the active requests is finished. The completion of the request processing is indicated by DONE = TRUE.
