F6217-984621702 SIS一般采用多重冗余結(jié)構(gòu)以提高系統(tǒng)的硬件故障裕度

安全儀表系統(tǒng)（Safety Instrumented System，簡稱SIS）是一種用于工廠控制系統(tǒng)中報警和聯(lián)鎖部分的安全控制系統(tǒng)，F(xiàn)6217-984621702能夠?qū)嵤﹫缶瘎幼骰蛘{(diào)節(jié)或停機(jī)控制，是工廠企業(yè)自動控制中的重要組成部分。

安全儀表系統(tǒng)主要具有以下特點(diǎn)：

覆蓋面廣、安全性高、有自診斷功能，能夠檢測并預(yù)防潛在的危險。
具有容錯性的多重冗余系統(tǒng)，SIS一般采用多重冗余結(jié)構(gòu)以提高系統(tǒng)的硬件故障裕度，單一故障不會導(dǎo)致SIS安全功能喪失。

應(yīng)用程序容易修改，可根據(jù)實(shí)際需要對軟件進(jìn)行修改。

自診斷覆蓋率大，工人維修時需要檢查的點(diǎn)數(shù)比較少。

可實(shí)現(xiàn)從傳感器到執(zhí)行元件所組成的整個回路的安全性設(shè)計，具有I/O短路、斷線等監(jiān)測功能。

F6217-984621702 安全儀表系統(tǒng)包括傳感器、邏輯運(yùn)算器和最終執(zhí)行元件，即檢測單元、控制單元和執(zhí)行單元。其中，傳感器用于檢測工藝參數(shù)，邏輯運(yùn)算器用于進(jìn)行邏輯運(yùn)算和控制，最終執(zhí)行元件則根據(jù)邏輯運(yùn)算器的結(jié)果執(zhí)行相應(yīng)的動作，如報警、停機(jī)等。

此外，F(xiàn)6217-984621702安全儀表系統(tǒng)的等級劃分也是衡量其可靠性的重要因素。根據(jù)安全等級系數(shù)，安全儀表系統(tǒng)可以分為一級、二級和三級等不同等級。其中，一級安全儀表系統(tǒng)的可靠性最高，三級最低。

總的來說，安全儀表系統(tǒng)是一種高可靠性的控制系統(tǒng)，廣泛應(yīng)用于工業(yè)自動化領(lǐng)域中，能夠保障工廠和企業(yè)的安全穩(wěn)定運(yùn)行。

The Safety Instrumented System (SIS) is a safety control system for the alarm and interlock part of a factory control system. The F6217-984621702 is capable of implementing alarm action or adjustment or shutdown control, and is an important part of the automatic control of a factory.

The safety instrument system mainly has the following characteristics:

Wide coverage, high safety, self-diagnostic function, can detect and prevent potential hazards.
Multiple redundancy system with fault tolerance, SIS generally adopts multiple redundancy structure to improve the hardware fault margin of the system, and a single fault will not cause the loss of SIS safety function.

The application program is easy to modify, and the software can be modified according to actual needs.

The coverage rate of self-diagnosis is large, and the number of points that workers need to check when maintaining is relatively small.

It can realize the safety design of the whole loop from the sensor to the actuator, and has the monitoring function of I/O short circuit and broken line.

The F6217-984621702 safety instrumentation system consists of sensors, logic operations and final execution elements, namely detection units, control units and execution units. Among them, the sensor is used to detect the process parameters, the logic arithmetic is used to carry out logical operations and control, and the final executive element executes the corresponding actions according to the results of the logic arithmetic, such as alarm and shutdown.

In addition, the classification of the F6217-984621702 safety instrument system is also an important factor to measure its reliability. According to the safety grade coefficient, the safety instrument system can be divided into one level, two level and three level. Among them, the first-level safety instrument system has the highest reliability and the third-level safety instrument system has the lowest reliability.

In general, the safety instrument system is a highly reliable control system, widely used in the field of industrial automation, to ensure the safe and stable operation of factories and enterprises.
