REXROTH FCS01.1E-W0011-A-04-NNBV R911311065开关量输出模块

REXROTH FCS01.1E-W0011-A-04-NNBV R911311065开关量输出模块逻辑地也叫机器逻辑地、主机电源地，是计算机内部的逻辑电平负端公共地，也是+5V等的电源输出地。如CPU的正负5伏、正负12伏的负端。需要接入公共接地极。
2.3屏蔽地（AG，Analog Grounding）
也叫模拟地，它可以把现场信号传输时所受到的干扰屏蔽掉，以提高信号精度。DCS系统中信号电缆的屏蔽层应做屏蔽接地。线缆屏蔽层必须一端接地，防止形成闭合回路干扰。铠装电缆的金属铠不应作为屏蔽保护接地，必须是铜丝网或镀铝屏蔽层接地。接入公共接地极。
2.4本安地
应独立设置接地系统，接地电阻≤4Ω。本安地的接地系统应保持独立，与厂区电气地网或其它仪表系统接地网的距离应在5m以上。
三、DCS系统接地方式
1、S7-1200 CPU 从固件版本V4.1起开始支持组态控制功能，使模块的组态和安装更加灵活。
2、设DCS系统专用独立的接地网；
3、设DCS专用接地网，经接地线、再接至电气接地网。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.
