Using a redundant PROFIBUS system makes it possible to considerably increase the availability and thus the reliability in comparison with a single system. One particular advantage is scalable redundancy that begins with a redundant PROFIBUS transmission link, continues with a redundant master and en...

Bus length and speedWhen a PROFIBUS network is installed, boundary conditions of the RS485 transfer technology must be observed. The electrical network uses a shielded, twisted pair cable. All subscribers are connected in a line-shaped bus. The transmission rate can be adjusted in steps from 9.6 kbi...

The maximum permissible bus length depends on the transmission rate and the bus cable type. Different cable types (designation A to D) for different applications are available for connecting PROFIBUS devices either each other or to network elements (Linking Devices, Repeaters). The electrical lines ...
