Configure the hardware. Now open a 2nd Portal and your original project that is not working. Drag and drop all the OBs/FBs/FCs, user datatypes and tags. Compile hardware. Download hardware. Hope for green lights on your hardware. Download software. Test. I have seen problems that are only solved in this way. If that does not work, remove the calls to Modbus blocks, adjust the versions for your Modbus blocks, then drag them back in and compile/download, and test. Your latest version of the MB blocks may not work for you. In the meantime, start a support call with Siemens so they can offer suggestions and maybe even firmware update for the rs485 module.
