Industrial automation in food processing or manufacturing often requires tailored heating solutions, especially when different products require different temperatures for optimal results. A PLC-controlled conveyor oven system can automate and optimize the heating of various products in a single process, ensuring consistent quality and efficiency. This article delves into a PLC programming solution using Omron CX-Programmer, which controls the heating process for products on a conveyor system, adjusts the oven temperature based on product type, and counts products as they undergo heating.
