Programming latch
WebWhat is the purpose of the Output Latch? In PLC programming, an output is tied to an electrical device that most often performs a mechanical action. A few examples of such devices include motor starters, relays, valves, solenoids and lights. The purpose of energizing an output is to toggle between the two states of the device tied to this output.
