Machines and systems can be linked with fieldbus couplers. This makes data exchange between different control worlds possible. A complex CPU-to-CPU communication can be omitted. Depending on the fieldbus, the integration takes place via device description files such as GSD, GSDML or EDS.
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module. Note: Individual modules cannot be combined with the IO systems of other manufacturers.
