Write a PLC programme that starts the motor when the start push button (PB) is pressed and stops it when the PB is released. If the PB is held down for more than three seconds, the motor is latched until the stop PB is pressed.
Push-button logic circuits are commonly used in PLCs (Programmable Logic Controllers) to control the process. Push-button logic circuits have four switches that are arranged in a 2x2 matrix.
The switches on the push-button logic circuit can be used to turn on and off electrical power, measure voltage, and provide feedback signals.
Push button latches are commonly used in automotive, industrial, and commercial applications. They can be found on the doors of cars, on the doors of warehouses, and inside factories.
A latch circuit is an electronic circuit that locks its output when a momentary input trigger signal is applied and maintains that state even after the input signal is deleted. Until the power is reset or an external signal is applied, this state will persist eternally.
Latching switches are turned on by the user and remain on until they are turned off. They do not necessitate the user's continual compression. Latching switches are used in the home for light switches, central heating switches, and stereos, among other things.
