Flexible Automation Solution with Decentralized Intelligence

Fieldbus systems ensure reliable data transfer between the control and sensor/actuator level. When considering future Industry 4.0 scenarios, flexible automation solutions and real-time data transmission become more important than ever. Ethernet IO modules from Pepperl+Fuchs comply fully with this task and quickly and easily connect field devices to the higher-level bus system. The modules support the most common Ethernet protocols: PROFINET, EtherNet/IP, and EtherCAT. The desired type can be set directly on the module using a rotary switch. Their multiprotocol capability enables direct Ethernet communication with all common control panels—and with just one device.



The Ethernet IO modules offer comprehensive diagnostic functions that improve transparency within the process. LEDs provide status information for each channel, allowing channel-specific diagnostics at all times. An integrated web server enables remote access to network parameters such as IP address, subnet masks, and gateways.

Equipped with a “decentralized intelligence” function, the modules are able to handle smaller applications without any dependency on a remote control panel. The modules evaluate parameters autonomously, and information is transferred to the PLC only if it is necessary.

This relieves the higher-level system and improves reaction times, supporting the demands of Industry 4.0 scenarios.



The module’s power connector with an L-coded M12 plug connection allows a higher current rating of up to 16 A. As a result, the modules are able to meet higher peak loads, and fewer cables are needed.

With a fully encapsulated housing, the modules are extremely durable and suited even for harsh conditions. The rugged design allows various mounting options. This eases installation and integration into existing plants. With this array of innovative features, Ethernet IO modules boost plant efficiency.


Intelligent Fieldbus Connection of IO-Link-Devices

With its product range of fieldbus modules, Pepperl+Fuchs offers Ethernet IO modules with integrated IO-Link master, allowing seamless communication from IO-Link-enabled sensors/actuators to the control panel. Up to eight IO-Link devices may be directly connected. Here, four channels are available for sensor technology and four channels for actuators. The IO-Link master makes seamless parameterization, diagnostics, and predictive maintenance possible down to the sensor/actuator level.

The benefits of IO-Link can be fully utilized via Ethernet IO modules with integrated IO-Link master. Transparent communication from the control panel level right down to the field level ensures efficient and reliable process flows. If maintenance is required or a device needs replacement, the existing parameter data is adopted automatically. When switching production, any modified parameter sets can also be transferred quickly and easily to several sensors simultaneously to prevent plant downtime. As a result, Pepperl+Fuchs is taking another step toward digital networking and transparency for the factory of the future.
