Challenges and Lessons Learned for the Design and Implementation of Large PROFIBUS Network

摘要

The onset of new and emerging technologies such as Intelligent Plant Instrumentation (IPI) is bringing fresh challenges to the design of instrumentation systems such as an interesting level of complexity in the size and design of the network. For example, large networks need to be designed to meet the necessary process requirements, and at the same time maintain the advantages that the smart instrumentation is able to provide through emerging digital data management systems. The design of data networks for IPI implies a 180 degree change in the vision of the system when compared to a typical hardwired system. The evaluation of the layers of network communication and their constraints becomes an important factor that needs to be addressed when designing large systems.
