The Greater Than or Equal function block evaluates input A to see if its integer value is greater than or equal to input B.
If input A is greater than or equal to input B: power will flow through the function block.
If input A is not greater than or not equal to input B: power will not flow through the function block.
According to the above example:
If MI 1 value is greater or equal to constant integer 35; then MB 50 will go to logic "1" (ON).
If MI 1 value is not greater or equal to constant integer 35; then MB 50 will go to logic "0" (OFF).
