In this example, a motor is controlled via a contactor. The InOut zone activates the contactor, while the inverted zone monitors the contactor feedback.
In this example, a motor is controlled via a contactor.
Logic Layer:
The contactor feedback is a normally closed contact and is modeled in the system layer as follows:
We use an InOut zone to switch on the motor for this task. This zone activates the contactor that releases the current to the motor.
The contactor feedback is monitored to ensure that the contactor is working correctly. The contactor feedback is a signal that indicates whether the contactor is switched on or not. If the contactor is switched on, the motor is activated and running.
To ensure that the zone is functioning correctly, it must be inverted. This means that the signal that activates the contactor is inverted. If the signal is typically "On," it will be set to "Off" in this inverted zone. This is necessary to ensure that the contactor is switched off when the zone is activated.
In addition, the "Keep Alive" function is activated. This function ensures the zone remains permanently active, even if the signal is temporarily interrupted. This ensures that the contactor remains activated and the motor is operated continuously as long as the zone is active.
This means that the motor remains active and in operation during the processing step, similar to the cylinder in the above example. This implies that the motor performs its function and performs the required actions during the operation step without being stopped or deactivated. The motor is expected to operate continuously during the processing step.
