Abstract: This article in detail introduced the programmable foreword controller development course and in our country development condition, and elaborated the new generation of programmable foreword controller technical present situation, asked in our country programmable foreword controller development question and the countermeasure.
1.Introduction
The programmable foreword controller is take the microprocessoras a foundation, the comprehensive computer, the correspondence, the networking as well as the utomatic control technology develop new generation of industry control device. The programmable foreword controller had more than 30 years history in our country developmentand the application, now it already widely applied to the national economy each industrial production domain, became raises the traditional industry equipment level and the technical ability important equipment and the formidable prop. Along with the globalinte gration economy development, diligently develops the programmable foreword controller in the our country large-scale application, formshas the independent intellectual property rights the programmable foreword controller technology, should be the general technical personnel's diligently direction.
