摘要
针对现有PLC的设计、制造的过程十分复杂,价格昂贵,不适合小批量生产、制造的缺点,现设计一种低成本简易PLC,对这种PLC进行硬件结构设计和系统软件设计与调试。经过实践可用于对具有一定工作工程的机械设备控制,来代替接触器、继电器控制系统提高控制可靠性。该可编程程序控制器构成的系统共可处理1 024 B,8 192个点的现场信号,应用前景很灵活,很广泛。
The design and manufacture process of the existing PLC are complex,and its cost is expensive,which is unsuitable for small-lot production and manufacture,so a simple PLC with low cost was designed. The hardware structure design,system software design and debugging for this PLC were conducted. The practice proves that the PLC can be applied to mechanical equipment control of a certain working engineering to replace contactor and relay control system,and improve the control reliability. The system composed of programmable controller can process the field signal with 1024 bytes and 8192 points,and has flexible and extensive application prospect.
