Just fix the syntax so it is structured text instead of c++ and add some alarms. Google "structered text rockwell" for more info.
Pretty sure you can handle it.
Only used Siemens myself but Im assuming its the same, you will also need to scale the input of the pt100, it will come in as an integer between 0 and 27648 I think if the input is set to 4-20mA. You will want to scale it to for example a real(float) of 0-100 Celcius depening onwhat the full scale is.
If your pt100 gives a 4-20mA signal but your analog input's hardware is 0-20ma then you will have to scale it from 5529-27648.
Then decide if you need a HMI (touchscreen) or not or use scada(pc) to control the process and display variables and stuff. You cant use printf since you dont have a screen built in I assume.
Im assuming in rockwell you can also monitor variables online in a watch table, not sure what they call it in rockwell.
Cheapest if you have a pc available would probably be advancedhmi running on a pc, because a decent hmi can cost over a thousand us dollars.
