RS485 to WIFI/Ethernet Can I read the 3 devices with your module via RS485 and send them to my server via modbus tcp or MQTT?

2024-05-23 21:53:10 Ask

Please I have some doubts about this module:

I have 3 RS485 devices all with different addresses on the network (01, 03 and 05) and also the modbus rtu addresses are different for each device.

Can I read the 3 devices with your module via RS485 and send them to my server via modbus tcp or MQTT?

As I have 3 different devices, there will be 3 different Modbus RTU addresses and also different reading register ranges. How to configure this in your module's?

1) RS485_TO_WIFI/ETH does not support MODBUS MQTT, and supports Modbs TCP

2) It can be supported using TCP, but MQTT does not support modbus. We will also strive to support modbus MQTT in the future.

3) If you need Modbus and MODBUS MQTT mutual transfer functions, please use this RS485 rotor ETH module:

When multiple modules are used at the same time, you can configure different request data frames to specify the corresponding module:
