摘　　要：DeviceNet现场总线是基于CAN总线的一种开放式、低成本、高性能的工业控制系统底层网络协议,现已成为IEC标准、欧洲标准和中国标准。介绍了DeviceNet协议的特点,给出了多变量变送器作为DeviceNet节点的开发实例,主要包括硬件电路构成和系统软件的实现。该变送器可以直接挂接在DeviceNet总线上,与主设备进行通信,实现对温度、压力和差压的准确测量。对DeviceNet的仅限组2从设备的设计有一定的参考价值。DeviceNet is an open,low cost and high performance network protocol in industry field control system based on CAN technology.it has been become IEC standard.Europe standard and China standard.An example of developing multi-variable transmitter as DeviceNet product has been presented in details after introduction of the characteristics of DeviceNet protocol.The example consists of the hardware circuit and the software.The transmitter that has functions of measuring temperature.pressure and differential pressure of flowing liquid can be directly connected to DeviceNet fieldbus to communicate with the master device.It would be remarkable reference to design other Group 2 Only Slave Devices.
