With PROFINET, is it always necessary to install two bus systems i.e. Ethernet & PROFIBUS?
Pure PROFINET solutions as well as combined PROFINET and PROFIBUS solutions are possible. The strengths of PROFINET lie in the integration of both bus systems in a common concept. The advantage is that in cases in which technical solutions do not exist for Ethernet, PROFIBUS can be used without the need to adapt the fieldbus protocol or field devices. An example of this would be motion control or safety-related applications.
