AS-Interface Master / Gateways Bihl+Wiedemann specialize in the development of ASi Masters and Gateways for the most commonly used bus systems. Using a Bihl+Wiedemann solution, you will benefit from the unique features such as the comprehensive diagnsotics capabilities in plain text via display, duplicate address detection, use of «1 Gateway, 1 power supply for 2 ASi networks» and the integrated Safety Monitors for ASi Safety at Work. |
AS-Interface Modules AS-Interface Modules connect standard actuators and sensors to ASi and therefore efficiently and cost-effectively to the controller/PLC. ASi modules have a varying number of inputs and outputs and are available for installation in an enclosure (IP20) or for use in the field (IP65/IP67). For field use the user benefits from the special piercing technology which makes conventional wiring obsolete. |
Safety Components In addition to the efficient transmission of standard data from the field to the controller/PLC, ASi safety at Work technology makes it possible to send safe signals up to PLe over the same 2-conductor ASi cable. This means safe I/Os can be checked and turned off right where the signal originates. The transmission of safe and non-safe signals over a single two-conductor cable immensely minimizes wiring while further optimizing the network layout. |

Bus Couplers / Master Simulators Thanks to the wealth of our experience with Gateways and bus couplers you will find at Bihl+Wiedemann a variety of «special solutions» for various coupling requirements. Our Master simulators not only make it possible to test the Gateway functionality of our ASi Masters. You can also test associated modules without having to write code for complicated controller programs. For example our PROFIBUS Master simulator can be used to work with any PROFIBUS modules using any desired. gsd file and even carry out automated checking using Windows dll files, whether the data are cyclic or acyclic. Many of our customers are themselves manufacturers of PROFIBUS modules and greatly appreciate the simplicity and universality of our Master simulators. |
Accessories In addition to the ASi Masters and ASi modules Bihl+Wiedemann also offers all the needed accessories for your ASi circuit. Particular expertise lies behind our network extension tools, which you can use to extend your ASi circuit beyond the usual 100m to as much as 1000m. |
Software We apply a great deal of our ASi expertise in providing you with the best possible configuration tools for ASi Masters and Safety Monitors. With our ASi Control Tools360 you have all the important test and configuration possibilities for your ASi circuit clearly organized on your PC. Our ASIMON360 software is the right configuration software for «ASi Safety at Work.» With it you can simply and easily create your ASi configurations directly on the computer using clear multi-window interfaces. Control III allows you to turn our ASi Masters into mini-PLCs. Software programmed in C allows pre-processing to be performed right in the gateway. In many applications the gateway can also be used as a stand-alone device, completely doing away with the need for a PLC. Our Ethernet-based devices also come with a Web server which enables remote diagnostics and maintenance even with computers not having pre-installed software. |
