PROFIBUS是一种国际化、开放式、不依赖于设备生产商的现场总线标准,广泛适用于制造业自动化、流程工业自动化和楼宇、交通、电力等其他领域自动化。PROFIBUS-DP作为PROFIBUS一个兼容部分,它是一种高速低成本通信,用于设备级控制系统与分散式I/O的通信,使用PROFIBUS-DP可取代24VDC或4~20mA信号传输。主要介绍了PROFIBUS-DP在城市轨道交通控制系统中的应用。
PROFIBUS is an international, open, field device-independent bus standard that is widely used in manufacturing automation, process automation and other areas such as building, transportation, and power automation. PROFIBUS-DP, a compatible part of PROFIBUS, is a high-speed, low-cost communication for communication between a device-level control system and decentralized I / O. PROFIBUS-DP replaces 24VDC or 4-20mA signaling. This paper mainly introduces the application of PROFIBUS-DP in urban rail transit control system.
