"i didn't have any idea about it."

That's probably because it isn't possible.
IP addresses aren't com ports, and you can't communicate directly with an RS485 device via the internet without a hardware device which acts as an internet device and passes info bidirectionally to the 485 comms link. The two aren't even slightly compatible as far as hardware and signal types are concerned.
And to use a hardware device to do it, you would need to look at the specific device manual (or talk to the manufacturer's technical support people).

If you have a 485 card in you PC, you can connect that to the internet, and write C# code to transfer data between the two, but IP addresses have nothing to do with com ports!
