Modbus RUT and websocket

I need help with RUT906/956 to use it as a modbus RUT “gateway”.

We need a solution where RUT connects to our server via websocket and we can send modbus rtu read/write commands to the device connected via modbus rtu. No other logic needed in RUT.

How could we best solve this? I am ready to also hire/pay for the solution if someone is capable of doing this.

Interested to provide “payed for” solution. For large fleet of RUT955 I already did customized commercial firmware, incl. MQTT to AWS-IoT, auto-failover wan/wifiwan/wwan, mqtt-data-queuing, remote firmware update OTA, ModBus/RTU R/W plus signal pre-processing, remote config of connected ModBus devices and RUTs themselves, VPN for remote maintenance, remote logging etc.

If you are still on the lookout to hire someone, I would be glad to help you out as what you are wanting done is within my skillset

I would suggest considering the Modbus TCP over Serial Gateway functionality mentioned here. This would allow you to send Modbus TCP requests to RUT9 device, which will then translate those requests to Modbus RTU and send them to the connected Modbus RTU device over a serial link.

Another option you can consider is the Serial Over IP functionality here. This will allow you to create a TCP connection between your RUT9 and your remote server/client, and forward all data to/from the serial device. In this case, the RUT9 can work in a client mode (initiate connections to the server), or in a server mode (accept connections).

Kind Regards,
