BUILDING THE DRIVER
It is recommended that you use the project file TECH.MDP for building the driver.
If you are familiar with the project development environment provided by Microsoft Visual C++, it's very easy to re-build the driver after you add any device-dependent code into the Tech Pack. When you have any problems regarding language itself, please refer to Microsoft Visual C++ on-line or printed manuals for help.
The following lists several basic steps that you may take to build an ONSPEC I/O driver with Tech Pack, and some hints that may be helpful for your work.
The I/O Template collects real-time data from and sends real-time data to the field instruments such as DCS, PLC, Controllers, Data Acquisition Equipment, I/O Cards/Boards. The data communication is usually accomplished through serial ports, network or direct memory access (DMA).
