How ODOT PN I/O Accelerated Transformation in Food&Beverage?

The food and beverage industry is a sector that can continuously create demand for consumers almost 24 hours a day. The constant need for "eating and drinking" ensures that the industry is vast, but it also faces fierce competition. In this context, the introduction of automated production lines not only improves production efficiency but also significantly enhances product quality and safety. As an important part of the food and beverage industry, bottled mineral water production has achieved full-process automation from raw material handling to final product packaging through the application of automation technology. This has greatly reduced labor costs, increased production efficiency, and boosted market competitiveness. 1.Overview of the Bottling Process

 The bottling process is a critical stage in the food and beverage industry, comprising the following main steps: （1）Blow Molding: Preforms are heated and blown into bottles using high-pressure air in blow molding equipment. （2）Filling: Processed drinking water or other liquid products are filled into the molded bottles. （3）Capping: After filling, the bottles are capped to ensure product sealing. （4）Labeling: Labels are applied to the capped bottles to indicate product information. （5）Packaging: Labeled bottles are packaged for easy transport and sale. Each step requires precise control and coordination, with control systems playing a crucial role in ensuring the efficiency and reliability of the entire production process. 2.Case Background

 Equipment Compatibility: There are compatibility issues between equipment and systems from different Manufacturers, which may require additional interfaces and conversion devices, increasing system complexity and cost. Environmental Adaptability: In environments with high temperature, high humidity, or electromagnetic interference, the performance and stability of automation equipment may be affected, necessitating special design and protective measures. 3.ODOT Application The blow molding equipment extensively uses ODOT remote IO modules. The main control system uses a Siemens 1500 PLC, with fourCN-8032-L devices as remote stations for controlling various components, including the main electrical cabinet IO, main rack IO, preform organizer IO, and rotary body IO. The preforms are heated by the preform organizer, then enter the rotary body, where they are rapidly inflated and cooled to form the final bottle shape. The bottles then move on to the next stage for filling and packaging, completing the entire production process.

 The control cabinet is installed above the blow molding machine's rotary unit. During operation, the rotary unit rotates at high speed and works in conjunction with numerous electric and pneumatic devices. Additionally, some network cables are exposed, and the equipment operates in an environment with significant electromagnetic interference.

 The customer uses the ODOT CN-8032-L Profinet network adapter, paired with IO modules, to monitor bottle preform positions, count preforms, and control pneumatic valves, air pressure, and heating temperatures. Operating stably under long-term full-load conditions with default factory settings, the modules ensure the continuous and safe operation of the factory. By using ODOT Remote I/O system, the bottled mineral water production line has achieved efficient and stable fully automated production. This not only increases production efficiency but also reduces labor costs and ensures consistency and stability in product quality. As technology continues to advance, automation control systems will play an increasingly important role in more industries, driving industrial upgrades and development.
