REXROTH FCS01.1E-W0011-A-04-NNBV R911311065開(kāi)關(guān)量輸出模塊邏輯地也叫機(jī)器邏輯地、主機(jī)電源地，是計(jì)算機(jī)內(nèi)部的邏輯電平負(fù)端公共地，也是+5V等的電源輸出地。如CPU的正負(fù)5伏、正負(fù)12伏的負(fù)端。需要接入公共接地極。
2.3屏蔽地（AG，Analog Grounding）
也叫模擬地，它可以把現(xiàn)場(chǎng)信號(hào)傳輸時(shí)所受到的干擾屏蔽掉，以提高信號(hào)精度。DCS系統(tǒng)中信號(hào)電纜的屏蔽層應(yīng)做屏蔽接地。線纜屏蔽層必須一端接地，防止形成閉合回路干擾。鎧裝電纜的金屬鎧不應(yīng)作為屏蔽保護(hù)接地，必須是銅絲網(wǎng)或鍍鋁屏蔽層接地。接入公共接地極。
2.4本安地
應(yīng)獨(dú)立設(shè)置接地系統(tǒng)，接地電阻≤4Ω。本安地的接地系統(tǒng)應(yīng)保持獨(dú)立，與廠區(qū)電氣地網(wǎng)或其它儀表系統(tǒng)接地網(wǎng)的距離應(yīng)在5m以上。
三、DCS系統(tǒng)接地方式
1、S7-1200 CPU 從固件版本V4.1起開(kāi)始支持組態(tài)控制功能，使模塊的組態(tài)和安裝更加靈活。
2、設(shè)DCS系統(tǒng)專(zhuān)用獨(dú)立的接地網(wǎng)；
3、設(shè)DCS專(zhuān)用接地網(wǎng)，經(jīng)接地線、再接至電氣接地網(wǎng)。Logically
Also called machine logic ground and host power ground, it is the common ground of the negative terminal of the logic level inside the computer and also the power output ground of+5V, etc. For example, the negative end of the CPU with positive and negative 5V and positive and negative 12V. It is required to connect to the common grounding electrode.
2.3 Shielding (AG, Analog Grounding)
Also called analog ground, it can shield the interference received during the field signal transmission to improve the signal accuracy. Shielding layer of signal cable in DCS system shall be grounded. One end of the cable shielding layer must be grounded to prevent closed loop interference. The metal armouring of armored cables shall not be used as shielding protection grounding, but must be grounded with copper wire mesh or aluminized shielding layer. Connect to the common grounding electrode.
2.4 Intrinsically safe place
The grounding system shall be set independently, with the grounding resistance ≤ 4 Ω. The grounding system of intrinsically safe grounding shall be independent, and the distance from the electrical grounding grid or other instrument system grounding grid in the plant area shall be more than 5m.
3、 DCS system grounding mode
1. The S7-1200 CPU supports the configuration control function since the firmware version V4.1, which makes the module configuration and installation more flexible.
2. Independent grounding grid dedicated for DCS system shall be set;
3. DCS special grounding grid is set, which is connected to the electrical grounding grid through the grounding wire.
