How to connect Arduino Uno to Ignition SCADA

I am trying to control the temperature of a system using Arduino uno(without wifi). I am using a ds18b20 temperature sensor and a dc fan as a final control element. I don't know how to use Arduino uno with ignition scada

You could use a modbus library and then connect to the uno in ignition via a modbus. I've done this with another scada package before

I have done this with Ignition, works a charm. Also, works well on Raspi!

Eitherway @Kathit_patel, as @nminchin has said Modbus is likely the way to go.
Especially, if you aren't that familiar with Industrial Automation as Modbus is a fairly easy protocol to get your head around and there are many good resources online!

For RPi's I'd use NodeRed. Travis Cox wrote a NodeRed module for Ignition
