C系列P型可编程序控制器的扩展处理

The Expansively Processing P Type Programmable Controllers

本文介绍将SYSMACC系列P型PC(可编程序控制器)通过扩展,增加输入、输出点数,具有A/D、D/A模拟量输入、输出功能.

This paper deals with the technology for expanding P type programmable controllers (PC) by means of expanding, adding input and output points and therefore functioning the controllers with A / D and D / A inputting and / or oulputting analogue values.
