介绍了DeviceNet现场总线应用层协议的软件实现过程和方法。该设计方法已成功地应用于DeviceNet通信适配器的开发中,实践证明所设计的DeviceNet通信适配器完全实现了DeviceNet应用层协议,符合DeviceNet规范的要求。同时对实现其他DeviceNet智能设备也具有借鉴意义。
The software implementation process and method of DeviceNet fieldbus application layer protocol are introduced. This design method has been successfully applied to the development of DeviceNet communication adapter. The practice has proved that the designed DeviceNet communication adapter fully implements the DeviceNet application layer protocol and meets the DeviceNet specifications. At the same time to achieve other DeviceNet smart devices also have reference.
