First question is do ı need to any configuration side of em277 module. I plug it and looked S7200 configuration via Microwin ı saw EM277 module with settings. I just set profibus address with switches. Also ı checked special memory bytes. ı couldn't see any fault. if ı need to do more configuretion for EM277 could you help me? [schnippschnapp] Do you have any example program for com between cp342 and em277? second question is splitted to configuring a CP342-5 as DP master?.

I think you should use FC1 and FC2 in your program Best regards, Wizard
