PROFIBUS Fieldbus system

What is PROFIBUS?

PROFIBUS is an open fieldbus standard for networking sensors and actuators. It is used in various areas of industrial automation technology, e.g. in manufacturing, process and building automation. PROFIBUS enables communication between devices from different manufacturers without special interface adaptations. PROFIBUS-DP is a variant optimized for speed and low connection costs for fast data exchange at the field level. The controller communicates mainly cyclically with the field level, e.g. the Bihl+Wiedemann PROFIBUS gateways and connected ASi devices, via a serial connection.

PROFIBUS Gateways

PROFIBUS ASi Gateways

PROFIBUS ASi-3 gateways in stainless steel offer an interface for a PROFIBUS fieldbus in accordance with IEC 61158 / IEC 61 784-1. These certified ASi gateways are available in various versions with IP20 protection rating. Some product variants enable Ethernet diagnostics and optionally allow functions of a small PLC to be executed in the gateway via a C program.

Safety, PROFIBUS ASi Gateways

The certified ASi gateways with integrated safety monitor are available in different versions with protection class IP20. Two product variants feature the Safe Link technology, which makes it possible to connect different system components easily and flexibly. One gateway offers integrated PROFIsafe communication for easy integration of the safe signals into the F-CPU.
