GEA's Launches T.VIS Control Head With IO-Link Technology

Monday, June 22nd, 2020 | 1091 Views

The degree of automation in production plants in the food, dairy and beverage industry is constantly increasing. This also increases the demand for intelligent field devices. Sooner or later this leads to a confusing multitude of interfaces with different mechanical and electrical characteristics. In general, the solution to this challenge is called IO-Link and GEA‘s T.VIS actuators are now available with this technology. In addition to the 24 Volt, AS-i and DeviceNet communication types already available in the T.VIS range, the IO-Link technology will now enable GEA valves to make the step into the industrial 4.0 world. IO-Link provides customers with a standardised solution that simplifies installation and offers extended diagnostic and parameterisation capabilities.


Access real-time data with the T.VIS control head program for GEA valves

The T.VIS actuator range for GEA valves offers significant efficiency benefits in the design and operation of food, dairy and beverage production and processing plants. Real-time diagnosis of data and direct access to sensor parameters, especially during valve setup and maintenance, improve the handling and operability of the valve unit. Problems can be anticipated before they escalate. The technology also enables greater plant effectiveness, identification of performance trends and reduction of downtime.


What distinguishes the IO-Link technology?

With the T.VIS control head with IO-Link technology GEA presents the consistent further development of the previous connection technology for sensors, actuators and thus also for control heads of the latest generation. IO-Link is the first globally standardised IO technology (IEC 61131-9) for communicating with sensors and also actuators down to the field level. The powerful point-to-point communication is based on the long-known 3-wire sensor and actuator connection without any additional requirements on the cable material.

An IO-Link system consists of an IO-Link master and one or more IO-Link devices. The IO-Link master represents the interface to the higher-level control level (PLC) and controls the entire communication with the connected IO-Link devices. This makes the system an intelligent solution at the field level.


 The advantages of IO-Link at a glance:

– IO-Link makes sensors and actuators capable of communication

– Process data are exchanged digitally with high signal quality

– Components can be parameterised centrally

– Diagnostic information is transferred from the valve to the controller and can thus be visualised in the operating system.

– Standardised and considerably simplified installation

– IO-Link is fieldbus-independent and can be integrated into all fieldbuses worldwide.
