Ethernet IO modules guarantee transparent communication from control to sensors and actors level. | Fieldbus Ethernet IO Modules by Pepperl+Fuchs

Benefits

Multi-Protocol Solution

The multi-protocol solution enables direct Ethernet communication from all standard PLCs to the fieldbus modules. These modules handle PROFINET, EtherNet/IP, and EtherCAT which reduces the number of components needed, supporting standardization in plant design. This also simplifies machine building for international markets, as one module covers different requirements.

Improved Connectivity

The L-coded M12 connector has a higher current rating of up to 2x16 A, providing a 70 % performance increase. As a result, fewer power cables are needed, higher peak loads can be met, and more modules can be daisy-chained together. The general standardization of the compact M12 connection brings plant operators maximum efficiency and uniform system design.

Decentralized Intelligence

The integrated logic of the new Ethernet IO modules makes it possible to solve applications self-sufficiently in the module itself, and to relieve control levels. This shortens response times and reduces communication expenditure generating more efficient processes.

IO-Link

Communication between IO-Link sensors/actuators and a fieldbus module with integrated IO-Link master enables parameterization, transmission of process and status data, and extended diagnostics. This communication base is a building block for future Sensorik4.0® applications—opening up new advantages in terms of plant transparency.

Highlights of the IO-Link Master

Enables continuous diagnostics and parameterization right down into the sensor/actuator level

Simplifies device replacement and commissioning: Automatic transfer of preconfigured parameters when several sensors are connected.

Supports 8 IO-Link channels for sensors (Type A) and actuators (Type B)

Is based on simple and economical wiring with unshielded standard cables

Is future-proof thanks to IO-Link standard IEC 61131-9

Decentralized Logic Simplifies PLC Software

With local control and decentralized operations, fieldbus communication and software components are not required in the main control panel—only diagnostic data are transmitted upstream.

The benefit of this can be seen in a conveyor system, where parts are sorted by correct position and size and, if necessary, removed via a compressed air control system. This process requires extremely quick reaction times, which are achieved by directly connecting inputs and outputs into the module.

Quick reaction times are possible because additional time needed for communication is no longer required, and time-sensitive dependencies on other processes are eliminated.

Quick Diagnostics, Maximum Transparency

The modules maintain maximum process transparency: Diagnostic parameters can be monitored directly from the module through a web interface or communicated back to the PLC. An integrated web server allows to access the device directly through a web browser, making it possible to view important information and change network parameters such as IP addresses and subnet masks.

LEDs are available on the modules, providing continuous status information and enabling channel-specific diagnosis. This increases productivity by allowing faults to be detected and fixed more efficiently.
