I don't understand why companies in systems integration sell hardware and software together in a package.

This is competitive and well articulated. But the more important reason is that the project needs, generally can do this kind of project of large companies can design hardware and software, so that the economy. Some system integration projects are designed to the logic control, articulation requirements are good, the division of labor is too fine instead of good. If the domestic enterprises, anyway, need to outsource hardware, through the hardware encryption, to prevent the integration of late three-way, so that the monopoly of future services and upgrades.

If there is a large automation project, such as power plants, steel mills, water supply and drainage, drinking water sewage city wastewater treatment, various chemical plants, coal mines, coking, batching, environmental monitoring, environmental monitoring, desulphurization or dedusting, furnaces and kilns, dock assembly, coal plants, such as conditions of the DCS, DIS, MIS, SCADA systems and other projects can be **** win-win cooperation.

At the same time, if there is a stand-alone automation system or small production line automation system can also be cooperation, but this type of system to have the amount, such as engineering vehicles, medical equipment, supporting control systems.

Contact: a five + four circles + 111 + nine, any special or non-standard centralized control system can be made very quickly, at present, the domestic industry is in a period of reshuffling, large-scale or historical companies are basically in the bottleneck.
