The new Ethernet IO modules from Pepperl+Fuchs not only meets the requirements of machine and plant builders, but also of Industry 4.0.

A module in a robust design for all standard Ethernet protocols, IO-Link, integrated intelligence for decentralized automation and diagnostic tasks—the new Ethernet IO modules from Pepperl+Fuchs not only meets the requirements of machine and plant builders, but also of Industry 4.0.

PROFINET, EtherNet/IP, and EtherCAT are the most commonly used Ethernet protocols in automation technology. Until now, machine manufacturers had to choose one of these module types depending on the control panel. The new Ethernet IO modules from Pepperl+Fuchs save you from the “agony of choice” and the resulting variety of variants. Thanks to their multiprotocol function, they are universally compatible with the above-noted Ethernet fieldbuses and thus ensure efficient and cost-reducing standardization of the fieldbus connection of machines and plants.

One version available in the portfolio of new Ethernet IO modules is equipped with an integrated eight-way IO-Link master, for direct connection of up to eight IO-Link devices. This makes it possible to set up a pre-fault indicator, condition monitoring for preventive maintenance, a simple restart after sensor replacement, or a digital sensor/actuator image of the overall system, to name just a few examples. This transparency through to the sensor or actuator can significantly improve process performance.

All Ethernet IO modules are equipped with a web server. During commissioning, the user can perform the complete parameterization via a web browser. During diagnosis and maintenance, it is possible to access status information and error messages directly. As a result, faults can be targeted and corrected at an early stage.

Decentralized intelligence is also integrated into the modules. This makes it possible to implement logical operations and process-level applications without needing to take a detour via the control panel.

Individual automation tasks can be implemented completely independently in the module—feedback to the controller is limited to a small amount of data, allowing the communication costs to be significantly reduced.

The new connection technology of the Ethernet IO modules is also in line with industry requirements. The L-coded plug-in connector in the industry-standard M12 offers up to 70% more current rating. This enables parallel wiring for energy management to be reduced and higher peak loads to be covered—all without additional wiring.

Fieldbus modules are used in the field—i.e., directly on the machine. The new Ethernet IO modules are optimally equipped for this often harsh environment. The metal housing provides the maximum mechanical robustness and an extremely tight seal against the ingress of dust and moisture. The electronics inside are also fully molded and thus protected against vibration and shock.
