In 2001, the country established the “Industrialization of Open Control Systems Based on Industrial Control Computers” industrial automation major project, with the goal of developing PC based control systems with independent intellectual property rights, occupying 30% (50%) of the domestic market within 3 (5 years, and achieving industrialization.

A few years ago, when “soft PLC” appeared, the industry believed that industrial PCs would replace PLCs. However, industrial PCs have not replaced PLCs to this day for two main reasons: one is due to system integration; Another reason is for the software operating system Windows NT. A successful PC based control system requires two points: firstly, all work must be completed by software on one platform

The second is to provide customers with everything they need. It can be foreseen that the competition between industrial PCs and PLCs will mainly be in high-end applications, with complex data and high equipment integration. Industrial PCs cannot compete with low-priced micro PLCs, which is also the fastest-growing part of the PLC market.

From the perspective of development trends, the future of control systems is likely to exist between industrial PCs and PLCs, and these signs of integration have emerged.

Like PLC, the industrial PC market has remained stable over the past two years. Compared to PLC, industrial PC software is very cheap

According to Frost&Sullivan’s estimate, out of the $700 million industrial PC market worldwide each year, approximately $85 million is for control software and $100 million is for operating systems. By 2007, the industrial PC market will double and become very attractive.
