With electronic technology, control technology, PLC from the simple The development of the digital volume control to a simple analog control and digital volume control with The bination of a partial substitute for the function of singleloop instrumentation. PLC39。s first major application in the automotive production line. With the application of Continuously expand the area of a variety of households in PLC. In order to meet the needs of different Application of the requirements of the needs of families with a strong PLC itself flexibility. Households PLC Factory solution is standardized, modular and work. Input, output signal into 20mA and so on, each signal using. A types of processing modules, each module there are multiple channels, so that the position can not With the size of the system. At the same time, also can reduce the R amp。 can connect field bus standard frequency Browser, MCC (Motor Control Center). The expansion of I/O also can be connected not with the controller. AC households can Convenient and enterprise work integration, the realization of chemical information. Ether has bee Layer standard for work monitoring. PAC fullfeatured short, in the factory since Action, only the user AC mining can be achieved so the control functions. Not the need for other control systems. Rockwell Automation in the work using Ether / IP, Device Net three work technology. And the realization of the three work Seamless work connectivity is a model of work architecture industries. The technology of nuclear Heart is the CIP (mon industrial protocol) protocol. PLC works Mod bus application is also very extensive. Aspects of the current Romanian Industrial Ether Rockwell Automation, Schneider pushed the main CIP Ether, Siemens and so the main push Ether Net / IP standard work protocol and workbased Prepared. special hardware technology. We all agree that industrial Ether Network will receive a wide range of applications. Ether can dominate the world but also necessary. On the one hand to verify interare still some technical problems yet to be solution Decision. On the other hand, the installation of the existing mature owned bus is very great. Extremely costly full replacement. With the development of electronic technology. PLC size is getting smaller and smaller. Small Is limited. Not better. R
