一、产品介绍：

    CEGM45 以太网交换机 Radisys 可靠性高，抗干扰才能强
　　高可靠性是电气操控设备的关键功用。PLC由于选用现代大规模集成电路技能，选用严厉的生产工艺制作，内部电路采取了*的抗干扰技能，具有很高的可靠性。例如三菱公司生产的F系列PLC均匀无毛病时间高达30万小时。一些使用冗余CPU的PLC的均匀无毛病工作时间则更长。从PLC的机外电路来说，使用PLC构成操控系统，和同等规模的继电接触器系统比较，电气接线及开关接点已削减到数百乃至数千分，毛病也就大大下降。此外，PLC带有硬件毛病自我检测功用，呈现毛病时可及时宣布警报信息。在使用软件中，使用者还可以编入外围器材的毛病自诊断程序，使系统中除PLC以外的电路及设备也取得毛病自诊断维护。这样，整个系统具有极高的可靠性也就不奇怪了。
　　配套齐全，功用完善，适用性强
　　开展到，已经形成了大、中、小各种规模的系列化产品。可以用于各种规模的工业操控场合。除了逻辑处理功用以外，现代PLC大多具有完善的数据运算才能，可用于各种数字操控领域。近年来PLC的功用单元很多出现，使PLC浸透到了位置操控、温度操控、CNC等各种工业操控中。加上PLC通讯才能的增强及人机界面技能的开展，使用PLC组成各种操控系统变得非常简单。

Product introduction:

CEGM45 以太网交换机 Radisys High reliability and strong anti-interference ability

High reliability is the key function of electrical control equipment. PLC adopts modern large-scale integrated circuit skills and strict production technology. The internal circuit adopts advanced anti-interference skills and has high reliability. For example, the F series PLC produced by Mitsubishi company has an average trouble free time of up to 300000 hours. Some PLCs using redundant CPUs have a longer average trouble free working time. From the external circuit of PLC, the control system is composed of PLC. Compared with the relay contactor system of the same scale, the electrical wiring and switch contacts have been reduced to hundreds or even thousands of times, and the problems have been greatly reduced. In addition, PLC has the function of self detection of hardware defects, which can announce the alarm information in time when the defects appear. In using the software, the user can also program the fault self diagnosis program of peripheral equipment, so that the circuits and equipment other than PLC in the system can also obtain fault self diagnosis and maintenance. In this way, it is not surprising that the whole system has high reliability.

Complete supporting facilities, perfect functions and strong applicability

Up to now, a series of large, medium and small-scale products have been formed. It can be used in industrial control occasions of various scales. In addition to the logic processing function, most modern PLCs have perfect data operation ability and can be used in various digital control fields. In recent years, many functional units of PLC have appeared, which makes PLC immersed in various industrial controls such as position control, temperature control, CNC and so on. With the enhancement of PLC communication ability and the development of man-machine interface skills, it becomes very simple to use PLC to form various control systems.
