本文就以太网在自动化领域应用现状及前景、以太网与现场总线技术等热点问题,从技术比较出发,发表了个人看法。本文认为:以太网在工厂管理层、车间监控层将成为主流技术,与互联网技术结合是未来eManufactory技术基础;在没有严格时间要求的设备层也将获得一定的发展;但对一般工业网络要求实时性、确定性的通信场合,现场总线技术还将处于主导地位;我们必须学会面对一个多种网络技术并存的现实世界。
This article on the Ethernet in the field of automation applications and prospects, Ethernet and fieldbus technologies and other hot issues, starting from the technical comparison, expressed his personal views. This paper argues that Ethernet will become the mainstream technology in factory management and workshop monitoring layer. The integration with Internet technology will be the foundation of eManufactory technology in the future. In the equipment layer without strict time requirements, it will also achieve certain development. However, for general industrial networks, real- In the case of sexual, deterministic communications, fieldbus technology will also dominate; we must learn to face the real world in which multiple network technologies co-exist.
