Using Siemens SIMATIC Step 7 program, write a PLC LAD program to control the system shown in the figure and described below: The figure shows part of a production line, where label quality is inspected. The system has a control panel with a start and a stop push buttons used to control movement of conveyor 1. With conveyor 1 moving and transferring products, products pass beneath a quality sensor, which detects product's quality (sensor works exactly like a capacitive sensor, but only detects defective products). When a defective product is detected, once it reaches the ejection station (detected by a capacitive proximity sensor), the conveyor stops, a double-acting cylinder (ejector) controlled via a monostable control directional control valve (DCV) pushes the product then retracts to the initial position, conveyor works again. Note that the cylinder has 2 limit switches to detect its fully retracted and fully advanced positions. Indicate the number of non-defective products. ejector cylinder start stop quality sensor sensor Conveyor rejected products Using Siemens SIMATIC Step 7 program, write a PLC LAD program to control the system shown in the figure and described below: The figure shows part of a production line, where label quality is inspected.
