“…It should be noted that even the rapid spanning tree protocol is not able to revert to a redundant path quickly enough to satisfy the real-time requirements of industrial Ethernet. As a result the majority of the redundancy protocols available for industrial use are proprietary [16].…”

Abstract-An industrial control network is a system of interconnected equipment used to monitor and control physical equipment in industrial environments. These networks differ quite significantly from traditional enterprise networks due to the specific requirements of their operation. Despite the functional differences between industrial and enterprise networks, a growing integration between the two has been observed. The technology in use in industrial networks is also beginning to display a greater reliance on Ethernet and web standards, especially at higher levels of the network architecture. This has resulted in a situation where engineers involved in the design and maintenance of control networks must be familiar with both traditional enterprise concerns, such as network security, as well as traditional industrial concerns such as determinism and response time. This paper highlights some of the differences between enterprise and industrial networks, presents a brief history of industrial networking, gives a high level explanation of some operations specific to industrial networks, provides an overview of the popular protocols in use and describes current research topics. The purpose of this paper is to serve as an introduction to industrial control networks, aimed specifically at those who have had minimal exposure to the field, but have some familiarity with conventional computer networks.

“…On the other hand, less compelling applications can need a network cycle time of some hundreds of milliseconds. Some manufacturers have proposed proprietary solutions, mainly based on rings as described in [8]. But they do no suit with fast applications using EPL as ring solutions healing can take from 20 ms (for the best ones) up to 500 ms.…”
