摘　　要：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,vendor-independent field bus standard. It is widely used in automation technology of manufacture and flow industry, as well as building, transportation and electric power. As a compatible part of PROFIBUS, PROFIBUS-DP is a high-speed and low-cost communication, which is used in field control system and distributed I/O. PROFIBUS-DP is a replacement of 24VDC and 4～20mA signal transmission. The application of PROFIBUS-DP to urban rail transit is introduced.
