lassi Posts: 6 Rating: (0)	Hi, I am trying to create a communication between CP 342-5 card and some frequency converters (ABB's ACS800). My question is how to configure the DP_RECV block for example in the following situation: CP-Cards start input address is 336 (hex#0150) and I have the status word (SW) of an FC in address "PIW 130". In other words I would like to read the 16bit status word from the DP slave, but I do not understand how to configure this in the block FC 2 (parameter RECV). Same problem applies for the DP_SEND-block. I also have DB addresses for the input / output words of the frequency converters, should they be used when using these blocks? Thanks
