HiUMENCHO,Darius, Thank you for your suggestions. Now I am able to communicate with the meter, I want to know the data format of the Modbus communication in S7-200. The exact problem is, When I am reading 20 registers from the Modbus slave (as per the slave manual) I am getting the data's at the correctreceivelocation, But if I am changing no. ofqueries the data is not coming in the same location. Please helpme to find out the data structure format of S7-200.I have communicated the same meter in S7-300 by using CP-341 and it was fine. I want to know how to make Modbus program formore then one query in S7-200 plc's. |
