1756-L61B 備份控制器可以自動(dòng)接管控制任務(wù)，保證系統(tǒng)的連續(xù)運(yùn)行

1756-L61B 可編程自動(dòng)化控制器（PAC）與可編程邏輯控制器（PLC）有以下幾個(gè)區(qū)別：
1. 名稱由來(lái)：在第一代PLC時(shí)期，PLC主要用于替代硬接線繼電器和氣動(dòng)計(jì)時(shí)器，那時(shí)被稱為可編程控制器，簡(jiǎn)稱PC。但是很快，在1980年代初期，PC這個(gè)名稱被個(gè)人計(jì)算機(jī)霸占了，于是就經(jīng)常使用PLC這個(gè)詞了。PAC這個(gè)名稱則出現(xiàn)于大概15年前，它的出現(xiàn)也許是為了將功能最強(qiáng)的PLC從其它稍遜一籌的弟兄們中區(qū)分開(kāi)來(lái)。
2. 定義：很多生產(chǎn)制造商在區(qū)分PAC和PLC方面存在困難，原因在于兩者之間有很多重要但是共同的特性。這些共同的特性和功能包括高速CPU，提供快速掃描；基于標(biāo)簽名的功能；大容量板載存儲(chǔ)；文檔存儲(chǔ)在控制器中；任務(wù)管理程序組織；多種內(nèi)置網(wǎng)絡(luò)協(xié)議；數(shù)據(jù)采集。
3. 功能：相較于千禧年之初的大多數(shù)PC機(jī)，最新的PLC和PAC處理器芯片的處理頻率要高得多。這種技術(shù)進(jìn)步適用于各個(gè)等級(jí)的控制器。在考慮CPU的性能和費(fèi)用方面，這更多的是生產(chǎn)制造商的一種偏好。在很多機(jī)器控制領(lǐng)域和其它需要非常快的執(zhí)行速度的場(chǎng)合，都需要這些高速CPU。

1756-L61B PLC的高可靠性主要體現(xiàn)在以下幾個(gè)方面：

硬件設(shè)計(jì)：PLC的硬件設(shè)計(jì)采用大規(guī)模集成電路技術(shù)，具有很高的可靠性。同時(shí)，PLC的電源、輸入輸出端口等關(guān)鍵部件都采用了抗干擾技術(shù)，進(jìn)一步提高了其抗干擾能力和可靠性。
冗余設(shè)計(jì)：一些高端的PLC采用了冗余設(shè)計(jì)，即主控制器和備份控制器同時(shí)工作，當(dāng)主控制器出現(xiàn)故障時(shí)，備份控制器可以自動(dòng)接管控制任務(wù)，保證系統(tǒng)的連續(xù)運(yùn)行。
自診斷功能：PLC具有自診斷功能，能夠?qū)崟r(shí)檢測(cè)自身的硬件和軟件狀態(tài)，一旦發(fā)現(xiàn)異?；蚬收希梢粤⒓催M(jìn)行報(bào)警或故障排除，保證系統(tǒng)的穩(wěn)定運(yùn)行。
可靠性設(shè)計(jì)：PLC的軟件系統(tǒng)采用了循環(huán)掃描、故障檢測(cè)、故障處理等可靠性設(shè)計(jì)技術(shù)，能夠減少系統(tǒng)故障的發(fā)生概率。
耐環(huán)境性：PLC的設(shè)計(jì)考慮了工業(yè)環(huán)境下的惡劣條件，如高溫、低溫、潮濕、振動(dòng)等，能夠在這些環(huán)境下穩(wěn)定運(yùn)行。
維護(hù)方便：PLC的模塊化設(shè)計(jì)使得其維護(hù)變得非常方便，一旦某個(gè)模塊出現(xiàn)故障，可以迅速更換故障模塊，保證系統(tǒng)的連續(xù)運(yùn)行。
綜上所述，PLC具有高可靠性，其硬件設(shè)計(jì)、冗余設(shè)計(jì)、自診斷功能、可靠性設(shè)計(jì)、耐環(huán)境性和維護(hù)方便等特點(diǎn)都使得其在工業(yè)自動(dòng)化控制領(lǐng)域得到了廣泛應(yīng)用。

1756-L61B Programmable Automation controller (PAC) and programmable logic controller (PLC) has the following differences:
1. Name origin: In the first generation of PLC period, PLC is mainly used to replace hard-wired relays and pneumatic timers, then called programmable controller, referred to as PC. But soon, in the early 1980s, the name PC was taken over by personal computers, and the word PLC was often used. The name PAC appeared about 15 years ago, perhaps to distinguish the most powerful PLCS from their less powerful brethren.
2. Definition: Many manufacturers have difficulty distinguishing between a PAC and a PLC because there are many important but common characteristics between the two. These common features and functions include a high-speed CPU that provides fast scanning; Function based on tag name; Large capacity onboard storage; Documents are stored in the controller; Task management program organization; Multiple built-in network protocols; Data acquisition.
3. Features: The latest PLC and PAC processor chips have a much higher processing frequency than most PCS at the beginning of the millennium. This technological advancement is applicable to all levels of controllers. In terms of CPU performance and expense, this is more of a preference of the production manufacturer. These high-speed cpus are needed in many areas of machine control and other situations where very fast execution speeds are required.

The high reliability of 1756-L61B PLC is mainly reflected in the following aspects:

Hardware design: The hardware design of PLC adopts large-scale integrated circuit technology, which has high reliability. At the same time, the PLC power supply, input and output ports and other key components have adopted anti-interference technology, further improving its anti-interference ability and reliability.
Redundant design: Some high-end PLC adopts redundant design, that is, the master controller and backup controller work at the same time, when the master controller fails, the backup controller can automatically take over the control task to ensure the continuous operation of the system.
Self-diagnosis function: PLC has a self-diagnosis function, can detect its own hardware and software status in real time, once found abnormal or fault, can immediately alarm or troubleshooting, to ensure the stable operation of the system.
Reliability design: PLC software system adopts reliability design technology such as cyclic scanning, fault detection and fault processing, which can reduce the probability of system failure.
Environmental resistance: The design of the PLC takes into account the harsh conditions in the industrial environment, such as high temperature, low temperature, humidity, vibration, etc., and can operate stably in these environments.
Easy maintenance: The modular design of PLC makes its maintenance very convenient, once a module fails, you can quickly replace the faulty module to ensure the continuous operation of the system.
In summary, PLC has high reliability, its hardware design, redundancy design, self-diagnosis function, reliability design, environmental resistance and easy maintenance and other characteristics make it widely used in the field of industrial automation control.
