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 AS-i Masters. You can also test associated slaves without having to write code for complicated controller programs. For example our PROFIBUS Master simulator can be used to work with any PROFIBUS slaves 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 slaves and greatly appreciate the simplicity and universality of our Master simulators.
