9、ng method is commonly used in traditional DCS. 欧洲安装规范（Europe Specificaiton） 在欧洲的工程设计和安装一般都要求按照图3所示的接地方式进行设计和施工，Ff接地推荐采用图3的方式。 In Europe, normally the projects grounding systems are designed as shown in Figure 3. For Ff project, this grounding method is recommended.,注意：Ff现场运行中故障的80%-90%都是由于接地或者屏蔽原因导致

10、的！ Note: 80% -90% of the Ff operation failures are due to bad grounding or shielding! ! !,基金会现场总线电缆 FOUNDATION fieldbus cable,IEC 61158-2对现场总线电缆的要求： Specifications of the fieldbus cable according to IEC 61158-2,基金会现场总线电缆 FOUNDATION fieldbus cable,IEC物理层规定标准的A型电缆参数如下表： Typical Ff cable characteristic
