Bihl+Wiedemann: Exploiting ASi Advantages in the PROFIsafe Environment


July 12, 2021

The ASi-5/ASi-3 PROFIsafe via PROFINET Gateway with integrated Safety Monitor is now also available as a single master without integrated I/Os: The BWU4018 is thus a cost-effective entry-level model that helps you exploit ASi advantages in the PROFIsafe environment.

Reduction of wiring costs

As opposed to Ethernet wiring, with ASi you do not need such things as plugs for the 24 V supply and bus connection. This way, you can significantly reduce your wiring costs and the installation effort.

A future-proof platform

Thanks to ASi-5 technology, you can now use the BWU4018 to also integrate ASi-5 nodes. Modern gateways also offer other advantages, such as:

  •    –   Field update capability for tamper-proof firmware and security updates
  •    –   Integrated OPC UA server for Industry 4.0 applications
  •    –   Integrated web server for fast system diagnostics

  •    –   PROFIsafe and Safe Link in one device
  •    –   1 ASi-5/ASi-3 master, PROFINET device
    •       –   reading ASi Safety input nodes via PROFIsafe
    •       –   writing to ASi Safety output nodes via PROFIsafe
  •    –   Up to 31 safe ASi nodes (each usable as inputs or outputs)
  •    –   OPC UA server and integrated web server for simple diagnostics
  •    –   Selection of mode of safe operation
  •    –   Chip card integrated for storing the configuration data
