步进式顺序控制器是一种通用性装置。它可以满足不同的生产自动线中的电气控制 需要。由于它利用了二极管矩阵和步进器的原理，不但大大提高了通用性，而且编制程 序也很容易。如果系列生产这种装置，那么，对于不同工艺要求的使用厂来说，只要根 据自己的工艺要求编出程序，然后在矩阵板上安插二极管，就可以拿到现场进行调试和 运行了。
Step-by-step sequence controller is a universal device. It meets the needs of electrical control in different production automation lines. Because it takes advantage of the principles of diode matrices and steppers, it greatly increases versatility and makes programming easy. If the series produces this kind of device, then for the process plant of different technological requirements, just according to their own technological requirements programming, and then placed in the matrix board diode, you can get the site to debug and run.
