Hi, Iam trying to communicate v20 using IM151-8PN/DP CPU.I have followed the different methods which are available in the forum.... So, i have finally selected uss protocol to communicate.I've followedall the instructions every thing according to the manual. When i made connection between v20 and IM using 1SI module....both Tx and Rx are blinking but no data getting transmitted..... I have checked some diagnostic parameters in v20 r2025[0...1] USS / MODBUS rejected telegrams r2028[0...1] USS / MODBUS parity error r2029[0...1] USS start not identified the above parameter are getting counted,so there is an error but i dont find what is that, i've downloaded the siemens program and it contains no errors.
