Soft Button for select module

Dear Expert,

I have plan to have additional temperature controller (TIC-B), that are input from our NGL analyzer (0.52%-1.5%) whereas existing temp controller (TIC-A) input base on temp transmitter (0-200F). Existing temp controller will regulate re-boiler control valve.

Command button already created, with writevalue either "0" and "1" whereas when user select existing so the controller active should be existing controller (TIC-A) and when user select additional then should be additional controller (TIC-B) will be active.

Please need your advice regarding how to parsing value from commandbutton to controller whereas only 1 selection that active and also how to control the temperature so that not exceed from certain value because if more than 155F will damage our seal pumps.

Thank you very much for your kind support

Regards,

Peki

  Hi Peki
  
  I have configured a similar one with pressure.
  
  As lower pressure is the preferable for our control purpose, I use low selector to pickup lower value between 2 readings.
  And in the selector block, there is a function to ignore the reading in BAD condition (IOBAD).
  
  I think you can use low or high selector to pick up one and you can use the selected the value for your TIC.
