WebIn this system, two pushbutton switches are connected to discrete inputs on a PLC, and the PLC, in turn, energizes the coil of a motor contactor relay by means of one of its discrete outputs. An overload contact is wired directly in series with the contactor coil to provide motor overcurrent protection, even in the event of a PLC failure where the discrete output … WebApr 23, 2024 · The first one will increase the speed of the dc motor. The second one will decrease the speed of our dc motor. So first, let us name some variables, so mod pin or the motor pin is connected to pin eight. The mod speed is equal to zero. So we have set this up to zero. Then push pin one or four for our first push. Button is connected to pin 12 push.
