Modbus TCP/IP Communication ESP8266 and Z Key 0 gateway

Projects Networking, Protocols, and Devices

I have a gateway (Z key 0) connecting to HMI (WM14-96) via RS485. The connection is still not okay due to different IP, but I need to read data using Modbus TCP/IP and display it on LCD using ESP8266MOD.

The data I would like to read is only displayed when I enter the IP address, such as Phase conductor voltage, Phase voltage, etc.

What I would like to know that, how am I going to do this in Microchip Studio/Arduino, in terms of codes?

The examples that I searched on the internet, usually involve 2 Arduino (master/slave), since my case is only read from gateway using modbus.

Many thanks

In what way is this a tutorial?
