6. Ff/HART故障表现及区别
DiFferences between Ff and HART
1. Ff仪表诊断报警的类型数量多于
HART，报警检测是基于宏周期的，
HART一般是轮询的。Ff instrument
Alarm / fault rate
diagnostic alarm type more than the
( based on unit )
number of HART, and the Ff alarm
detection is based on the macro
cycle, HART alarm detection is generally
polling.
2. 通信报警不同。DiFference
communication s and alarms.
1. 现场总线具有相当程度的“容错性”，故障具有
“潜伏性”；Fieldbus has a considerable degree Alarm type contrast
of " tolerance ", " potential "; ( based on equipment )
2. 现场总线设备共用一个网段，故障源和故障发
生点有时分离，具有“交叉性”；Fieldbus devices
share a segment, the fault source and fault point
sometimes separate with the "cross ";
3. 现场总线通信可能受到干扰，间歇性的干扰使
得故障表现出一种“随机性”；Fieldbus
communication may be subject to
interference, intermittent interference makes the
fault to show a " random ";

7. Ff故障原因分类
Classification of Ff Failure Causes
 除了仪表的本体以外，常见的是接线、进水问题。except
the instrument body, common wiring, water problems.
 对故障原因的分类统计有利于预防性维护措施的制定。
Classification and statistics on the fault reason is
conducive to the development of preventive
maintenance measures
 根据故障多发的情况，采取相应的改进措施。According
to the multiple fault situations, take corresponding
measures.
Note: Proportion is for reference only

9. 现场总线网段诊断及故障源排除
Ff Segment Failure Diagnosis and Exclusion
在接线柜采集数据。一般情况下，数据集中采集可
以安排在停车机会之前进行。Not for the
deployment of online diagnosis system of the
factory, in the cabinets of data collection. In general,
data collection can be arranged in the parking
opportunity before.
对数据进行整理，选择需要排查的对象。连接待检
查网段，在现场接线箱处，采用排除法（依次断开
分支，观察指标是否恢复），进行故障源的定位。
To organize the data, select the object needs
investigation. Connection to network, in the junction
box, exclusive method ( disconnect the branch,
observed whether recovery), location of fault
source.

11. 现场总线诊断数据关联分析
Fieldbus Diagnostics Data Correlation Analysis
诊断数据分布特征-复合型 Physical
layer parameters exceed

——一般情况下，幅值和不平衡超标比较突出。其
中，应主要关注不平衡因素。不平衡降低了网段的
抗干扰能力，应特别关注 In general, amplitude
level and unbalance exceed the standard more
prominent. Among them, should be the main
concern imbalance factor. Unbalanced lower
segment of the anti-interference ability, we should
pay special attention to.
“设备类型+物理层指标”合并分析
“ Type of equipment + physical
layer index” combined analysis
——应注意到设备本体作为网段的一个组成部分，
在正常的情况下，对网段的性能也会造成的叠加的
影响。Attention should be paid to the body of the
device as part of a segment, under normal
circumstances, the impact on performance of the
segment will also cause the stack.

13. 现场总线网段诊断数据记录表
Fieldbus Segment Diagnostic Data Record
记录表应有辅助的信息。包括DCS端口、接线箱、
接线柜端子、设备厂家型号。由于网段配置是动态
的，可编制程序从INtools和AMS的数据库中自动扫
描生成。Records should be auxiliary information.
Includes a DCS port, junction boxes, cabinets,
equipment manufacturers type terminal. Because
the network configuration is dynamic, can be
programmed from INtools and AMS database
automatic scanning.
企业根据自己的实践，制定合理的诊断参考指标。Enterprises according to their own
practice, formulate reasonable diagnostic reference index.
注意在正常工作状态下的“背景”噪声/电平。Note that in the normal working state
under the " background “ noise / level.
尽可能消除不平衡，提高网段抗干扰和免疫能力。To eliminate the unbalanced as far
as possible, to improve the anti-interference ability and immune network.
