Communication of Fx PLCs over MODBUS TCP/TP

3 posts in this topic

Hi,

I want to communicate Mitsubishi PLCs Fx1N, Fx2N and Fx3G over MODBUS TCP/IP protocol to HMI.Is there any MODBUS TCP/IP module available for these units?

hello,

depending on other things, it maybe would be cheaper to use some mitsu HMI (and will be much easier), because based on what i know, you will have to buy ENET card for each of your PLCs (FX3GE have enet port, but with locked ports under 1000, so modbus is mostly unaviable because it is using port 502, so you'll have to buy ENET-502 card), and tbh im not even sure if older PLCs have 502 versions of enet cards...

 

Also there is program to use modbus TCP done by mitsubishi but only for FX3, so you will have to adapt it for older ones...

@Sanaullah10 For FX3G may be use FX3U-ENET-P502.
