Digitalize your Food & Beverage plant with IO-Link 

Food and beverage manufacturers are under pressure to improve efficiency, ensure consistent product quality and meet growing requirements for traceability, safety and compliance. Digitalization helps by making process and device data more accessible, giving teams greater transparency across production and enabling faster, better-informed decisions. 

But digital transformation does not always require complex infrastructure.  

Food and beverage plants rely on auxiliary services like steam, water or industrial gases that are best served by basic instruments. In those cases, more sophisticated devices simply add unwanted complexity and cost. IO-Link is an established standard for devices which, while basic, provide the data-rich visibility and controllability benefits of digital technology.   

Maintaining and replacing field devices can be time-consuming, particularly when configuration must be performed manually. Once the IO-Link system becomes operational, maintenance, repair and operation (MRO) is accelerated. New repair and maintenance concepts become possible, through IO-Link’s self-diagnosis and self-parameterization capabilities, with value added to process measurements by detailed status and error data. Sensors often provide additional information, such as temperature, device status or continuous measurement values.    

IO-Link offers a compelling alternative to traditional non-digitalized devices such as 4-20mA transmitters or digital input switches, which only permit one process variable per cable pair. Such devices also require scaling and local configuration – operations that must be repeated manually every time a device is exchanged.  

IO-Link offers easy and efficient integration through using standardized function blocks. It also complements Industrial Ethernet architectures. While Industrial Ethernet is often used for high-end critical process instrumentation and advanced applications, IO-Link operates alongside it extending digital connectivity to more basic field devices, helping manufacturers gain visibility across a greater proportion of their plant. 

• IO-Link devices can be parameterized through the engineering system or with software tools. This eases device configuration and reduces stockholding by eliminating multiple variants. Parameterization can be done remotely from the host system.  
• Installation is less complex as all IO-Link devices connect to their masters via standard 3 or 5 core unshielded cables to 20m length, and standard M12 connectors.  
• Maintenance, repair and operation (MRO) is accelerated through IO-Link’s self-diagnosis and self-parameterization capabilities: process measurements are enhanced with detailed status and error data.  
• Failed devices can be replaced quickly, with minimal risk of manual entry errors, special knowledge or tools. Parameters are automatically loaded from a central parameter storage point into replacement instruments.  

Not every measuring point requires the functionality of a high-end Ethernet device. However, every measuring point can contribute valuable operational data.  

Smart Ethernet devices like valve islands, remote IOs, recorders, liquid analyzers and flow measurement devices are digitalized with Industrial Ethernet, PROFINET or EtherNet/IP. Now, basic devices are also becoming digitally accessible with IO-Link: This makes offline parametrization, data transparency and plug-and-produce device exchange available for all devices. Endress+Hauser’s IO-Link portfolio supports a unique choice of process variables, including level, pressure, flow and temperature.
