plc IO module status of the industrial sector in general and the reasons behind

Our automation industry chain two - the underlying field instruments (especially transmitters and actuators), the upper integrated automation software is the weakest link. Our own design and manufacture of PLC micro smart plc  smart transmitters only 9% of the domestic market. Top-level control software integrated weak, partly because the characteristics of the process of industrial enterprise users do not understand the profound lack of accumulated experience, thereby constraining the top-level integration capabilities and the ability to quickly enter the market segments (industrial enterprises subject to state on design enterprise qualifications prescribed threshold is also one reason). User market for their industrial technologies / products do not agree, restricted the practice of self-developed industrial product PLC plc digital input output module  improvement opportunities.
For these reasons, domestic control system is difficult to enter the critical major projects, the core, the main equipment, the majority of this market is still a monopoly of foreign industrial control systems.
(B) for the majority of discrete factory automation PLC system, the situation is not optimistic.
 The current scope of application of PLC technology, in addition to covering a large chemical, electric power companies in almost all PLC plc cpu modules  industries. However, the current application of PLC market, more than 95% are occupied by foreign products, domestic enterprises absolute disadvantage.
Three) PLC system hard-reliance, industry, research and development platform is missing.
First, their enterprises and institutions, small scale, decentralized operations, not thrive.
