In order to use the PCFL AIN 984LL Function block in Unity Pro you must create a Real data type for the Low Engineering Unit, High Engineering Unit and Scaled output as shown below
The Raw input usually range from 0-4095 (INT)
High Eng unit Word 5 and 6 (Real)
Low Eng unit Word 7 and 8 (Real)
Scaled output Word 13 and 14 (Real)
Summary:
If the raw analog input is 0-4095 and you want this to equate to 25-500 units of something you would enter 25 for Low Engineering Units and 500 for High Engineering Unity and the Output will then be 25 for an analog input of 0 and, 250 for an analog input of 2048 and 500 for 4095.
Attached is a document that outlines how to determine/select the raw analog input range.
