Connectivity for all common fieldbus systems

Beckhoff provides an extensive range of fieldbus components for all common I/O and fieldbus systems. The wide choice of I/O components means that the bus system best suited to the particular application can be chosen.

EtherCAT

EtherCAT (Ethernet for Control Automation Technology) is the Ethernet solution for industrial automation, characterized by outstanding performance and particularly simple handling.

Ethernet TCP/IP

The advantages of Ethernet, such as high data transmission rates, easy methods of integration into existing networks, and a wide range of services and interfaces are also found in the Beckhoff Ethernet products.

PROFIBUS

PROFIBUS is widely used as a fast bus for decentralized peripheral components (PROFIBUS DP). In addition to PROFIBUS DP Beckhoff also supports the standard for drive communication, PROFIBUS MC.

PROFINET

PROFINET is the open Industrial Ethernet standard of the PNO (PROFIBUS Nutzerorganisation).

EtherNet/IP

EtherNet/IP is the Industrial Ethernet standard of the ODVA (Open DeviceNet Vendor Association). It is based on Ethernet TCP/IP and UDP/IP.

CANopen

The effective utilization of the bus bandwidth allows CANopen to achieve a short system reaction time at comparatively low data rates.

DeviceNet

DeviceNet is a sensor/actuator bus system that originated in the USA, but meanwhile is increasingly being used in Europe and Asia. DeviceNet is CAN-based (Controller Area Network).

Interbus

Interbus is a sensor/actuator bus with low configuration expenditure. The summation frame protocol of this master/slave system offers high efficiency in cyclic communication.

SERCOS

SERCOS was originally developed as a fast fiber optic bus system for drives. Thanks to the Beckhoff SERCOS Bus Coupler, the advantages such as high data rate and short cycle times can now be provided for the I/O peripherals, too.

CC-Link

CC-Link (Control & Communication Link) is an open bus system for communication between the control and fieldbus level. It is predominately used in Asia.

Modbus

Modbus RTU is an open, serial communications protocol based on the master/slave architecture. Due to its open standards, Modbus TCP is common for the use of Ethernet in the fields of automation.

RS232, RS485

The “classic” serial interfaces, RS232 and RS485, continue in wide use. The Beckhoff RS485/RS232 I/O modules use a simple, published serial communication protocol that is easy to implement.

IO-Link

IO-Link serves to connect sensors and actuators to the control level by means of an inexpensive point-to-point connection. As an open interface, IO-Link can be integrated in all common fieldbus systems.

EnOcean

EnOcean enables the battery-free transmission of switching signals and measured values and is mainly used in building automation.

BACnet

BACnet (Building Automation Control Network) is a standardized, manufacturer-independent communication protocol for building automation.

Further subsystems

The integration of subsystems is possible using communication terminals.
