I have already added a MODBUS TCP device to ignition. But, is it possible to add a serial device to Ignition, from a port?

Yes, if you also have the gateway serial support module installed. Then the list of drivers to pick from will include Modbus RTU.

I don’t have ‘Gateway Serial Support Module’ installed. Where can I get it? **It’s not available in Ignition installer package.**

Interesting. Included in the zip installers only. You’ll just have to download and add it separately.
