The concepts are the same for every brand, but the details of implementation are different for each. Fundamentally you have to obtain the data, convert to engineering units, determine if and what type of control action is required, convert the decision to the required output info, and transmit that info to the field control device.

This is one of those disarmingly simple questions that could take a full semester course and decades of field experience to satisfy. I suggest you start by readig the appropriate sections of the manuals for both the PLC and the programming software.
