Best Answer

The basic function of a comparator in a PLC (Programmable Logic Controller) is to compare two input signals and determine if they are equal or if one is greater than the other. It typically outputs a boolean value (true or false) based on the comparison result. This comparison operation is used for decision-making within the PLC program, allowing for control and automation of processes based on the input conditions.
