Our ASi PROFINET Gateways – High Availability and Ideal for Siemens PLCs
ASi PROFINET Gateways with and without integrated Safety monitor: Immediately available from us in large quantities
Are you looking for ASi gateways with PROFINET interface to connect AS-Interface (ASi) to a PROFINET control system or Siemens PLC? Then we recommend two items from our "Bihl+Wiedemann's Choice" range: BWU3847 (for 1 ASi circuit) and BWU3852 (for 2 ASi circuits).
Do you also need Safety? Then the "Bihl+Wiedemann`s Choice" articles BWU3955 and BWU3952 (for 2 ASi circuits) are ideally suited. Both gateways have an integrated safety monitor and thus make it possible to solve safety functions completely without expensive higher-level safe control.
For standard applications:
ASi PROFINET Gateways without integrated Safety monitor
We recommend the "Bihl+Wiedemann's Choice" articles BWU3847 and BWU3852 for almost all standard applications. Here you also benefit from our new power supply generation.
However, if you need more than 4A per ASi circuit, you can also use the ASi PROFINET Gateways BWU3848 (for 1 ASi circuit) and BWU4257 (for 2 ASi circuits).
For Safety applications:
ASi PROFINET Gateways with integrated Safety monitor
We recommend the "Bihl+Wiedemann's Choice" articles BWU3955 and BWU3952 for almost all Safety applications. Here you also benefit from our new power supply generation.
However, if you are dependent on a specific higher-level F-CPU - e.g. due to the use of safe Siemens drive systems - you can alternatively use the ASi PROFINET gateways BWU3954 (for 1 ASi circuit) and BWU3953 (for 2 ASi circuits). Both gateways offer an integrated PROFIsafe communication for easy integration of the safe signals into the F-CPU.

This video uses a simple configuration as an example to show you how to set up an ASi-5/ASi-3 PROFINET gateway in ASIMON360 and integrate it into the Siemens control system. The video tutorial also includes a quick start guide as PDF.

To exchange the ASi Master, you only have to add a new GSDML file. The device description file can be downloaded from our website and be integrated into the control system. This transfers all necessary data to the control system, thus enabling easy integration of the ASi Master and naming of the data to be transferred.
