Industrial protocols are standardized communication methods used in industrial automation and control systems. They enable different devices, such as sensors, actuators, and controllers, to exchange data efficiently and reliably. Common examples include Modbus, PROFIBUS, and Ethernet/IP, which help ensure interoperability among equipment from various manufacturers. These protocols define rules for data formatting, transmission, and error handling, making it easier for systems to work together. By using industrial protocols, companies can improve productivity, reduce downtime, and enhance the overall performance of their operations, leading to more efficient manufacturing processes and better resource management.
