The Greater Than or Equal To instruction is a ladder logic rung input instruction that compares two values. If Source A is greater than or equal to Source B the logic to the right of the instruction, or rung-condition-out, is enabled and disabled otherwise. The values can be constants, tags or any combination.
Strings can be compared. The software compares the hexadecimal value of the characters to determine if one string is greater than or less than another.
