Abstract

The invention relates to a communication system for interchanging data in an automation system for communication between central and peripheral devices. A converter is connected into the communication path between the central devices and peripheral devices and being designed for line-bound communication with the central device and for wireless communication with the peripheral devices.

Claims

1. A communication system for data interchange in a technical automation installation for communication between central and peripheral devices, wherein a converter is connected in the communication path between the central and peripheral devices and has a predeterminable number of clearly associated peripheral devices, and is designed for cable-based communication with the central device, and for wireless communication with the peripheral devices.

2. The communication system as claimed in claim 1, wherein the peripheral devices are field devices.

3. The communication system as claimed in claim 2, wherein the field devices can be configured via the communication link.

4. The communication system as claimed in claim 1, wherein the peripheral devices are input/output assemblies.
