Almost all of the nodes available for Node-RED are listed on [flows.nodered.org](http://flows.nodered.org) take a look there and see if there is a node that meets your requirements

@ukmoose please help to configuration in raspberry pi to get modbus data using usb port.  
i searched for the same but there was getting data using python in raspberry pi.  
how to get data on node-red using usb port ? (rs485 to usb converter)  
or any other method pl guide.  
thank you.

most rs-485 devices can look like serial type devices to the PC. hopefully yours can too, and if so then the standard serial port nodes may work for you - or the modbus nodes that talk serial.
