are equipped with CPU, which can realize the quality judgment and scalar transformation of the acquisition and output signal, plug and remove the fault with power, and replace it randomly. The PLC module is just a simple electrical conversion unit without intelligent chip, and the corresponding units are all paralyzed after failure.
8. Now the functions of high-end PLC and DCS have been almost the same, DCS network and distributed database also has a strong function of timing scanning, at the same time, the operation and simulation of the amount of the amount of more skilled.
In 1968, America’s biggest carmaker, general motors (GM) in order to adapt to the need of production technology constantly updated, ask for a more reliable than a relay, and the function is more complete,
the response speed faster new industrial controller, and puts forward a new generation of controller from the perspective of the user should have ten conditions, immediately caused a development boom. The main contents are: (1) convenient programming, can modify the program on site; (2) Convenient maintenance, using plug-in structure; The reliability is higher than the relay control device; ④ the volume is less than the relay control panel; Data can be directly sent to the management computer; The cost can compete with the relay control panel; ⑦ input can be mains; The output can be mains,
