I plug Cp342 card to S7-300 312C cpu and ı configured like DP master. But CP342 has given Bus Fault. I read manual İts written that master device which are Cp342 card will configure Em277 card. I think ı need to give only profibus adress number with swtiches for EM277. Do you have any example program for com between cp342 and em277? splitted from profibus communication between CPU 312C with Cp342 to Em277.
