When I put the WP231 in stand alone mode using the DIP switch and use the "accessible devices" in TIA, I do see the module showing up with, But have no clue how to link the module with my S7-1500 with PN/IE_1 subnet.

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!)

I looked everywhere for any docs on how to configure the Siwarex without using the siwatool, I aksed the support, they say I need the Siwatool to even be able to configure the Siwarex WP231 as a stand alone module in the first place. No Good info on where to find the Modbus TCP/IP connection adresses anywhere without having the Siwatool to begin with. On the S7-1200 with Siwarex WP231, you just import the WP231 module in Device configuration, grab the HW-ID of the WP231 module, download the WP231 libary, then use the pre made FC and DB blocks and you're done. I would love to know how you were able to map out the data addresses. Sincerely Mehdi
