What should you watch out for when configuring a CP342-5 as DP master? With the DP_Send you transfer Data from CPU to CP -> output data for the CP. With the DP_Recv you transfer Data from CP to CPU -> input data for the CP. You have to transfer all outputs for example with one DP_Send. Think this is your problem. So the datarange you transfer has to cover all outputs. Sorry, couldn't open your project. I got no STEP7 available at the moment. Hope you could understand what I was trying to explain. Best regards Sabine
