IO-Link and comprehensive diagnostics are important for maintaining and troubleshooting your machines. These innovative, high-performance ethernet communication modules can help optimise your installations.

Managing the Demands of Modern Industry and Beyond

If industrial process control sensors are to manage the demands of the future manufacturing processes, they need to do more than simply deliver process data to a PLC. An industrial process control sensor must be able to communicate with multiple receivers and send and receive data to and from higher-level information systems efficiently.

Ethernet IO modules

The Pepperl + Fuchs Ethernet IO modules with integrated IO-Link master deliver first-class communication between system management and process sensors and actuators as they assume a gateway function between Ethernet and IO‑Link. With these capable ethernet modules up to 8 IO‑Link devices may be directly connected, with 4 channels available for sensors and 4 channels for actuators.

The ICE1 series IO-Link master enables integrated diagnostics and parameterisation from the control level right down to the process sensor level, and commissioning times will be  reduced primarily in large production plants. Ultimately, this means that Ethernet IO modules with integrated IO-Link master can be incorporated into the requirements profile of innovative machine and plant manufacturers easily, forming a crucial component of Sensorik4.0.

Ethernet IO modules

Sensorik4.0 is the next generation of interconnected sensor solutions from Pepperl + Fuchs that helps bring Industry 4.0 to life.

IO-Link Masters with OPC UA Interface, Dependable Information Exchange from Field to Cloud

In addition to the ICE1 masters, designed for PLC-based applications, two other modules are available for use in cloud-based and hybrid systems: the ICE2 (EtherNet/IP) and ICE3 (PROFINET) IO-Link master series.

These 2 ethernet modules support industrial protocols such as EtherNet/IP, PROFINET, and MODBUS TCP, and provide an OPC UA (Open Platform Communication Unified Architecture) interface in addition to real-time fieldbus protocols.

Ethernet IO modules

The open architecture of OPC UA allows cross-vendor, platform-independent, and the interoperable collaboration of machines in processing environments and makes communication between machines and computer or cloud-based systems possible, both in closed networks and via the internet.

Both IO-Link masters come with web-based configuration for setting all module parameters and all connected IO-Link devices (web IODD operation).  When replacing or expanding modules, all the module settings can be saved as a separate file and transferred to a new device using the module cloning function. OPC UA ensures a constant exchange of information across all levels so that plant processes can be designed more efficiently.

The King of Level Sensors – The KingCrown CleverLevel PL20 Series from Baumer

Down with Vibrating Fork Sensors, long live the King! The KingCrown CleverLevel PL20 Series Level Sensors are setting the stage as the most dependable and versatile level detection solution for a wide variety of troublesome media and processes.

With an adaptive-trigger function, these capable level sensors are a step ahead of vibrating fork sensors, automatically adjusting to all media without parameterisation. Applications vary from dry running protection for pumps through reliable overfill protection or leak detection to the selective detection and masking of foam or separating layers.

360 Degree Process Visualisation, Even in Daylight!

Robust process visualisation is built-in using 360° LEDs which provide real-time information on the process status, with 5 defined colours which can indicate whether the process is working as intended, the sensor is switching, or if there is an issue. Additionally, the colours can be used to indicate which medium is being measured and analogue values ranging from 4…20mA can be read out.

It doesn’t matter whether it’s bulk goods, powders, liquids or foam, or if the medium is sticky or has high or low viscosity, the KingCrown Level Sensor is the new King in town!

During industrial cleaning processes, such as CIP cleaning, sensors can switch incorrectly as they cannot differentiate between the process and cleaning media. The PL20 Level Sensors master this challenge by ignoring cleaning media. Also, media adherence, which can be caused by pasty materials, doesn’t affect these sensors, which adjust their switching level without the need for parameterisation.


Hot, Humid, No Problem!

In very humid areas, or those with temperature changes or water spray, a rugged impermeable design is needed to prevent sensor malfunctions. With exceptional resistance to impacts and fracturing during installation and production the KingCrown PL20 Series is perfect for demanding working conditions. Designed according to Baumers proTect+ Impermeability Concept, the PL20 Level Sensors are ideal for these challenging conditions. (Learn more about the Baumer proTect+ here).

Beverage and Rugged Industrial Application Versions

A built-in IO-Link interface provides easy access to valuable data, additionally it allows easy, location-independent parameterisation of the level sensor.

Available in two versions, with multiple mounting options, the PL20H for Food and Beverage process use and the PL20S variants for demanding high-pressure industrial applications.

PL20 Series Level Sensor Features and Benefits

  • 5 Multicolour LEDS, 360° real time status display even in daylight
  • Versions for Hygienic and Industrial applications, can be used in open tanks
  • Long term impermeability over entire service life according to Baumer proTect+
