Endress+Hauser offers a wide range of process instrumentation with IO-Link technology for digital communication.

IO-Link is enjoying increasing popularity, with demand for the communications standard growing rapidly, especially in the food & beverage industry. The fieldbus-independent technology for point-to-point communication is easy to use and provides a cost-effective way to digitalise industrial plants. Endress+Hauser, a leading provider in the industry, offers a wide range of IO-Link products for a large selection of process parameters.

IO-Link is regarded as an established standard for measurement devices with basic functionality, offering advantages such as data transparency and additional control through digital technology. Integrating IO-Link-capable sensors and actuators is especially popular with suppliers of machines or skids for the food & beverage industry.

Analog signals and digital communication

The majority of IO-Link sensors can also be operated in analog mode (4–20mA) with some simple configuration changes to the instrument, thus allowing production workflows to remain in place. If extra information such as diagnostic and service data is required, in addition to the actual process parameters, an installed IO-Link-capable instrument can be simply switched to a digital signal.

A simple step towards Industry 4.0 and the Industrial Internet of Things (IIoT)

Although IO-Link is not the most powerful communications standard for process engineering, instruments with IO-Link interfaces support the transmission of helpful metadata to ensure stable and efficient production. Furthermore, the smart sensor profile is designed for simple engineering, which reduces the effort required by plant operators to integrate sensors into their systems. Endress+Hauser also offers high end Ethernet devices which are well supported by basic IO-Link devices for a complete plant automation solution.
