16 downloadsThe attached PDF and example GX Works3 Project show how to set up your FX5U/FX5UC PLC via parameters to read and write to a Modbus/TCP Server without writing any code. This methodology does not work for the iQ-R or FX5UJ CPUs and their built-in Ethernet Port. For those CPUs please reference the Predefined Protocol function for setting up a Modbus/TCP Client. On the iQ-R platform if you purchase an RJ71EN71 network card, you can use the same methodology shown in this setup via the add-on Ethernet module.
