Serial communication-RS-485 using NODE RED

Can I get steps for RS-485 communication between Raspberry Pi and Energy Meter using Node Red programming Tool?
I have Node Red Tool and USB to Rs-485 conveter.

Don't see why not, with the serial port node it shouldn't be a problem.
What energy meter you want to read out?

Schneider Electric Engery Meter

What should be included in Node-Red Flow?

did you ever accomplish this rs485 to usb to node, in the interface communication, Successfully???
