GE (>=)

The GE instruction compares Integer, Real, Time, Date, and String input values to determine whether the first is greater than or equal to the second.
Equality testing of Time values for TON, TP, or TOF is not recommended.
Languages supported: Function block diagram, ladder diagram, structured text.
This instruction applies to the Micro810, L20E, L50E, and L70E controllers.
