基于VxD技术的通用硬件设备驱动程序的设计

Design of General Hardware Drive Program Based on VxD Technology

结合工控软件设计经验 ,提出了一种利用VxD技术、Modbus通信协议 ,设计通用硬件设备驱动程序的思想。为使用Modbus通信协议的自动化仪表 ,特别是一些PLC、单片机提供了一种方便。

Combining with the experience of process control software, the concept of design of general hardware drive program by using VxD technology and MODBUS communication protocol is stated. Thus an ease, stable and effective communication strategy is provided to automation instruments using MODBUS communication protocol, especially PLCs.
