过去的10年中,为了赢得工厂层的控制权,在不同的总线阵营之间展开了争论。现场总线包含很多种类,列举其中一些如DeviceNet,ControlNet,Foundation Fieldbus和PROFIBUS。这一名单中甚至不包括一些分散控制系统(DCS)和PLC网络的专用工业网络和现场总线。每个工业网络和现场总线为特定离散或过程制造的应用而进行优化,并且为一些任务如低成本设备连接,总线供电设备,冗余和容错,本征安全性,远程标定和诊断,确定性的分散控制等提供专门性能和能力。面对大量的选择,用户认真地为工厂和车间中
Over the past 10 years, in order to win the control of the factory floor, there has been a debate between different bus camps. There are many types of fieldbus, including some of them such as DeviceNet, ControlNet, Foundation Fieldbus and PROFIBUS. This list does not even include some specialized industrial networks and field buses that control the DCS and PLC networks. Each industrial network and fieldbus are optimized for specific discrete or process-created applications and are ideal for tasks such as low cost device connectivity, bus powered devices, redundancy and fault tolerance, intrinsic safety, remote calibration and diagnostics, deterministic Decentralized control to provide specialized capabilities and capabilities. The face of a large number of choices, the user seriously for the factory and workshop
