Final answer:
In a PLC control system for a moving bench in a production line, the valve controlled by KM3 is responsible for the filling process, though the entire operation is orchestrated by the PLC.
Step-by-step explanation:
In designing a PLC control system for a moving bench that carries raw materials through various positions, including position A for loading, position B for filling, and back to A for unloading, the component that controls the filling process is typically a valve.
The valve is often controlled by a relay or a contactor, in this case, designated as KM3. As for the motion of the bench, it is generally driven by a motor. However, the overarching control of the sequence of operations, including the activation of the valve and motor, is managed by the Programmable Logic Controller (PLC). The PLC would execute the programmed instructions to ensure that the moving bench stops at position B, the filling begins by opening the valve, and then proceeds to the next steps of the cycle.
In a PLC control system for a moving bench carrying raw materials, the component that controls the filling process is the Valve controlled by KM3.
The PLC (Programmable Logic Controller) is the main controller in the system, responsible for managing and coordinating various processes. However, the specific actuation of the filling process is carried out by the valve controlled by KM3.
The valve is used to regulate the flow of raw materials into the bench during the filling process. It can be controlled and operated by the PLC, which sends a signal to open or close the valve as per the required workflow.
