>=   GE

Operator - Test if first input is greater than or equal to second input.


IN1 : ANY   First input
IN2 : ANY   Second input


Q : BOOL    TRUE if IN1 >= IN2


Both inputs must have the same type. In LD language, the input rung (EN) enables the operation, and the output rung is the result of the comparison. In IL language, the GE instruction performs the comparison between the current result and the operand. The current result and the operand must have the same type.

Comparisons can be used with strings. In that case, the lexical order is used for comparing the input strings. For instance, "ABC" is less than "ZX" ; "ABCD" is greater than "ABC".
