Hello K S kumar, Well, there exist no official Siemens Ready-for-Use project regarding a S7-1500 plc with profinet port to Siwarex WP231 weighing module. But attached you can find my example project. In the past, I “played” a little bit regarding this topic. Maybe my example project helps you. Important is the function block “MB_CLIENT” in OB1, network 1, in my example project. To control the “MB_CLIENT”, you can use the watch table „MODBUS_Watchtable“. For example, if you would like to execute the zeroing- or tare-command in the watch table „MODBUS_Watchtable“, you have to do: 1. Set „MB_MODE“ to „1“ (1 = write) 2. Set „MB_DATA_ADDR“ to „40920“ (40920 = for commands) 3. Set „MB_DATA_LEN“ to „2“ (2 = two words for a command) 4. Set „MB_DATA_PTR[0]“ to „1001“ (= zeroing) or „1011“ (=taring) Set „MB_DATA_PTR[1]“ to „1“ (= Trigger-flag) 5. Set „REQ“ to TRUE for one-time (I had to zip the zap-file to upload it to my post!)
