Posted 16 Nov 2020 Hello, I have an M2I Top RW (model: 1000WD) connected to a Schneider Modicon M221 PLC. The HMI is connected and I is working perfectly reading data from the PLC via ethernet. I can't seem to find a way to write to the PLC from the HMI. I would like to control the PLC from the HMI, I know this is possible with Fatek PLCs with the same HMI model. please help - how would I create a bit command from the HMI to the PLC? what registers? what inputs in the PLC? thanks Share this post Link to post Share on other sites
