[HELP] MODBUS RTU over TCP multiple devices on one TCP connection #1172

Closed LukaszDuss closed 9 months ago

LukaszDuss commented 10 months ago

Describe the issue I need to configure 15 sensors that are connected to device with modbus rtu over tcp. I can only open one TCP connection due to limitation of my device.

Is it possible/how to configure modbus.json (v3) like modbus.json (v2), so my device will open just one TCP connection but still recognize 15 different sensors??

Connector name (If you need help with some connector/converter): MODBUS TCP with RTU

Versions (please complete the following information):

@samson0v Is it now possible to configure the gateway to fetch data from multiple sensors through one TCP connection with the latest release ?

Thank you
