Posted 2 Nov 2021 Hello brothers! Please, I have a project that uses an FX3U-30MR plc connected to a 16-output expansion board, via rs485 modbus network. I am using Work2 software. I am not able to COMMUNICATE the plc FX3U-30MR with the requested 16 output expansion board. Please, can anyone help me? Thanks!!

Posted 3 Nov 2021 Which model of expansion board do you use? It is Modbus or ASCII serial? Share this post Link to post Share on other sites
