Development of Industrial Control System Software in Windos

Precise control of industrial control system may be realized with programs of device driver, ISP interrupt service developed by WinDriver. Taking lognitudinal interrupt signal of NC System as an example, VxD was developed with WinDriver, MyDriver.c file that to handle external interrupt and control device was created. According to needing function requirements, interrupt service program was rewritten. The file was compiled into VxD:MyDriver.vxd with nmake instruction. The communication between MESSAGE and VxD was realized throughuser-defined message. VxD was called by application to control hardware and external device.
