大容量及超大容量开关量输出扩展电路逻辑的研究

RESEARCH ON THE EXTENSION CIRCUIT LOGIC OF THE ON/OFF TYPE OUTPUT WITH MULTI-AND SUPER-MULTI-LINE

本文作者所提出的方案和研制的系列模板，是为了在ＳＴＤ机笼外任意扩展开关量输出点数而专门设计的，这一成果圆满地解决了工业现场任意多点（几百点、甚至上千点或更多）开关量的输出问题。

The project researched and the series of the cxtension cards developed by the author of this paper are designed specially for arbitrary extension of the ON/OFF-type output imCs ontside tile STs BUS racks. Using this result, the problem about outptlt of very big amotlt of ON/OFF-type lines (several huncdreds, or even thousands of output points, or much more) at the indtlstrial fields has been solved successfully and satisfactorily.
