Y'all correct me if I am wrong
Since you are using an ML1500 you will need to obtain an analog input card, possibly 1769-IF4 and an analog output card, possibly 1769-OF2.
In RSL500 you will need to go into the project tree under Controller to I/O Configuration and install the cards, the slot you place them in will determine their addresses, the manual(s) should provide those details.
Take a look at the SCP instruction, it is possible to make the input transducer to directly work the vent valve, the precise "how" depends. From what you have mentioned so far I doubt PID would be necessary, as mentioned not sure about the analog being necessary.
You may get a lot of help on the project but you have to provide details before anyone can provide anything substantial.
