Fieldbus Foundation


Fieldbus Foundation™

Is an all-digital, serial, two-way communications system that serves as the base-level network in a plant or factory automation environment.

See our range of Fieldbus Foundation cables.




The main use of SafetyBUS is the communication of data with safety relevant content. SafetyBUS is found where the data integrity and timely delivery of data is required for the protection against risks.


See our range of SafetyBUS Cables.

AS-Interface AS-i


AS-Interface (AS-i)

Developed to have an inexpensive alternative to the lower fieldbus level (sensor/actuator) of Factory Automation. Normally used in connection with PROFIBUS, CAN and DeviceNet.
