    CEGM45 以太網(wǎng)交換機 Radisys 可靠性高，抗干擾才能強
　　高可靠性是電氣操控設備的關鍵功用。PLC由于選用現(xiàn)代大規(guī)模集成電路技能，選用嚴厲的生產(chǎn)工藝制作，內部電路采取了*的抗干擾技能，具有很高的可靠性。例如三菱公司生產(chǎn)的F系列PLC均勻無毛病時間高達30萬小時。一些使用冗余CPU的PLC的均勻無毛病工作時間則更長。從PLC的機外電路來說，使用PLC構成操控系統(tǒng)，和同等規(guī)模的繼電接觸器系統(tǒng)比較，電氣接線及開關接點已削減到數(shù)百乃至數(shù)千分，毛病也就大大下降。此外，PLC帶有硬件毛病自我檢測功用，呈現(xiàn)毛病時可及時宣布警報信息。在使用軟件中，使用者還可以編入外圍器材的毛病自診斷程序，使系統(tǒng)中除PLC以外的電路及設備也取得毛病自診斷維護。這樣，整個系統(tǒng)具有極高的可靠性也就不奇怪了。
　　配套齊全，功用完善，適用性強
　　開展到，已經(jīng)形成了大、中、小各種規(guī)模的系列化產(chǎn)品?？梢杂糜诟鞣N規(guī)模的工業(yè)操控場合。除了邏輯處理功用以外，現(xiàn)代PLC大多具有完善的數(shù)據(jù)運算才能，可用于各種數(shù)字操控領域。近年來PLC的功用單元很多出現(xiàn)，使PLC浸透到了位置操控、溫度操控、CNC等各種工業(yè)操控中。加上PLC通訊才能的增強及人機界面技能的開展，使用PLC組成各種操控系統(tǒng)變得非常簡單。

Product introduction:

CEGM45 以太網(wǎng)交換機 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.
