In this procedure, you will use Control Studio to create from scratch a module to monitor the tank level. The module will have one analog input function block (to allow reading of the analog input signal) and one output, a promoted parameter. Using a promoted parameter for an output makes the value of the output easier to access systemwide. Promoted parameters are on the Special Items palette.
You will also do the following:
Edit the IO parameter of the analog input block to identify the Device Signal Tag for the level transmitter, LT-1.
Change the OUT_SCALE parameter on the analog input block from the default value of 100 to 10,000 to reflect the 10,000-gallon capacity of the tank.
Change the HI_HI_LIM value will be changed to 1000.
Add history collection to the PV of the AI block so that the tank level can be trended in the Process History View application.
