In this context, you just must set the key on the EM277 to the right Profibus Adress. The DCS make all the job and read / wirte data directly on the V area. You don't need to program any SW.

Data to be sent to DCS: You have to put it in the configured V-area. So it can be read by DCS. Data from DCS: You can find it in the configured V-area. Best regards, Wizard
