摘要
由局域和广域网以及有线和无线通信系统组成的异构网络将发挥日益重要的作用;然而,需要的不仅只是实时、安全和保密的通信,渴望的情境感知也将通向基于现场的通信服务;因此,这些功能性将越来越多的影响自动化领域通信方法的复杂性;由于目前现场总线系统已在工厂自动化领域达到一个稳定阶段,所以将主要探讨在自动化领域内使用以太网和异构网络的近期发展情况,并指出未来的分布式自动化系统需要使用更多的机制以便于适应自动化功能的地理分布。
Heterogeneous networks, consisting of local and wide area as well as wired and wireless communication systems, will play an increasing role. However, there is not only a need for real-time, safe and secure communication. The desired context awareness leads to the usage of location-based communication services. Thus, the functionalities will influence more and more the complexity of the communications approach within the automation domain. Since the Fieldbus systems has reached a stable phase within factory automation currently , this paper will mainly deal with the ongoing development in the field of using Ethernet and heterogeneous networks. Future scenarios of distributed automation require more mechanisms for the geographical distribution of automation functions.
