被誉为当今世界最杰出的产品PC,是微机技术与继电器常规控制相结合的产物,是在顺控器、一位微机和微机控制器的基础上发展起来的新型控制器,它很好地解决了由I/O接口引入的干扰问题,并且采用梯形图编程,直观易懂,为已编程的逻辑提供了一种“接线网络”,从而减少了器件间的硬配线,所以它在工业控制领域里显示了强大的生命力。 Known as the most outstanding product in the world today, PC is a product of the combination of microcomputer technology and conventional relay control. It is a new type of controller developed on the basis of a sequencer, a microcomputer and a microcomputer controller. Solved the interference problem introduced by the I/O interface, and adopt ladder programming to be intuitive and easy to understand. It provides a “wiring network” for the programmed logic, thus reducing the hard wiring between devices, so it is in the industry. The control field shows a strong vitality.
