Ladder logic unlatched

The important part in this example is to keep the signal on even when the operator releases his finger from the push button. What we really need to do is to latch the input signal for both start and stop. This is not a usual way to start a motor. This is only to demonstrate the use of the Latch/Unlatch instructions. By … See more In this example we need to start/stop the motor. When the start button is pushed we want to start the motor, and when the stop button is pushed we want to stop the … See more This problem could also be solved with another technique. The rung below will result to the same solution as the previous method. How does this work? Rung0: … See more WebA latch is like a sticky switch – when pushed it will turn on, but stick in place, it must be pulled to release it and turn it off. A latch in ladder logic uses one instruction to latch, and a second instruction to unlatch, as shown in Figure 1 below. The output with an L inside will turn the output D on when the input A becomes true.
