In PLC programming, subtraction is commonly paired with which other function?

In PLC programming, subtraction is commonly paired with addition because they are inverse operations. When designing control logic or mathematical computations within a PLC, addition and subtraction often complement each other to achieve desired outcomes. For instance, if you want to calculate a net value, you might add and subtract different inputs to arrive at a total.

This relationship allows for efficient programming where one can manage cumulative values or offsets systematically. When performing calculations, adding a value to an existing total and subtracting another value to adjust for any decreases work together seamlessly to maintain accurate measurements or conditions within the system.

In many practical applications, control systems that monitor processes frequently need both operations to ensure values are balanced, reflect changes, or adjust for errors. This close connection in functionality makes understanding their relationship essential for effective PLC programming.
