P+F安全栅
对比齐纳式和隔离式安全栅的特点和性能后可以看出，隔离式 安全栅 有着突出的优点和更为广泛用途，虽然其价格略高于 齐纳式安全栅，但从设计、施工安装、调试及维护成本来考虑 ， 其综合成本可能反而低于齐纳式安全栅。在要求较高的工 程现场几 乎无一例外地采用了隔离式安全栅作为主要本安防 爆仪表， 隔离式安全栅已逐渐取代了齐纳 式安全栅，在安全 防爆领域得到了日益广泛的应用。
路，给设计及现场施工带来 极大方便。 2.对危险 区的仪表要求大幅度降低，现场无需采用隔离式的 仪表。 3.由于信号线路无需共地，使得检测和控制 回路信号的稳定性和抗干扰能力大 大增强，从而提 高了整个系统的可靠性。 4.隔离式安全栅具备更强 的输入信号处理能力，能够接受并处理热电偶、热 电 阻、频率等信号，这是齐纳式安全栅所无法做到 的。 5.隔离式安全栅可输出两路相互隔离的信号， 以提供给使用同一信号源的两台设备使用，并保证 两设备信号不互相干扰，同时提高所连接设备相互 之间的电气安全绝缘性能。
P+F安全栅的组态主要指对温变式安全栅的 组态，下面我们大概了解一下，温变式安全 栅组态软件的安装与一般组态。
2015.11.16
安装位置：安全栅安装于安全场所，接收来自危险区的信号,输 出安全信号到安全区或危险区。 安全栅的结构形式：常见的分为齐纳式和隔离式安全栅 齐纳式安全栅：电路中采用快速熔断器、限流电阻或限压二 极管以对输入的电能量进行限制，从而保证输出到危险区的 能量。 隔离式安全栅：采用了将输入、输出以及电源三方之间相互 电气隔离的电路结构，同时符合本安型限制能量的要求。
隔离式安全栅
隔离式安全栅：带有电流隔离功能的安全栅，称为隔离式安全栅，简称隔 离栅。 构成：通常由回路限能单元、电流隔离单元、信号处理单元 回路限能单元中最核心的电路为安全栅基本限能电路，辅助有用于驱动现 场仪表的回路供电电路和用于仪表信号采集的检测电路。 电流隔离单元包括变压器隔离组件、模频转换和频模转换电路。 信号处理单元则根据各品种隔离栅的功能要求实施信号处理。
安全栅作业指导书
安全栅作业指导书一、作业目的：安全栅在线故障处理过程中，应采取的预防措施，确保装置安全运行。
二、适用范围：大聚P+F及重油LB930安全栅。
三、采用标准：以P+F安全栅和LB930安全栅为例四、工作原理：1．大聚安全栅结构工作原理：大聚安全栅使用德国P+F集团的齐纳安全栅,包括多种型号。
KF系列隔离栅的现场侧端子与系统侧端子用不同颜色区分，如果有两组或以上的端子，可通过在端子上设置编码，使用端子组之间不会互相插错。
采用轨道供电后，隔离栅的配电就变得简单，易于掌握，不易出错，并且能很方便地实现冗余供电。
除了信号隔离功能外，还可以实现多种其他的功能，如信号分配，信号转换，报警设定等。
齐纳安全栅的作用，实际上是不让高电压或大电流传到现场仪表，使现场仪表的能量始终在安全范围之内，从而实现系统的本质安全防爆。
其结构原理如图1-11.1所示，电路由快速熔断器FA1，限压元件VD1、VD2 （齐纳二极管或二极管），限流电阻R1（电阻器或非线性元件）三部分组成。
正常操作条件下，非本安端1、2 之间所加的电压低于最高电压Vmax（更低于齐纳二极管的齐纳电压）,此时VD1、VD2处于不导通状态，除有极微小的漏电流以外，是“开路”状态，安全栅电路等效于一个电阻串联在信号回路内，只要漏电流小于规定值，安全栅电路不会影响系统的正常工作。
当非本安端发生故障,例如在非本安端1、2之间因某种原因混入高电压，使齐纳二极管VD1、VD2 反向击穿,呈“导通”状态，此时齐纳二极管VD1、VD2 把混入的高电压限制在齐纳电压上，在安全栅的本安端3、4 上不会出现高电压，齐纳二极管一旦导通以后，其电流急剧上升（雪崩过程）把串联在电路中的熔断器FA1 瞬时熔断，切断了至现场的高电压，防止了高电压引爆现场爆炸性物质的危险,从而保护了现场设备及人员的安全。
当现场（危险区内）发生故障，例如负载短路了，安全栅电路中的限流电阻R1立即起限流作用，把短路电流限制在某一个电流值之内，这个电流值是安全值，故现场也是安全的。

However, as the modules under consideration are only one part of an entire safetyfunction they should not claim more than 10% of this range, i.e. they should be better than orequal to 10-4 for SIL 3 and better than or equal to 10-3 for SIL 2.The modules under evaluation can be considered to be Type B components. However, the components that can contribute to a disturbance of the safety system are considered to be TypeA components.For Type A components the SFF has to fulfill the requirements as stated in table 2 ofIEC 61508-2 which are the following:Hardware fault tolerance (HFT)0 1 2 SIL 2 60% ≤ SFF < 90% SFF < 60%SIL 3 90% ≤ SFF < 99% 60% ≤ SFF < 90% SFF < 60%The following tables show under which conditions the critical components of the two modulesthat can contribute to a disturbance of the safety system fulfill this requirement (considering onlyone communication line being part of the safety function).Table 1: KFD2-HMM-16 together with KFD0-HMS-16 without additional module interfaceT[Proof] = 1 year T[Proof] = 5 years T[Proof] = 10 yearsPFD AVG = 1.23E-06PFD AVG = 6.13E-06PFD AVG = 1.23E-05than 10% of this range, i.e. to be better than or equal to 10-3. The PFD values even fulfill the requirements of higher SILs but the system does only fulfill the architectural constraints requirements (HFT/SFF) for SIL 2 which are set by table 2 of IEC 61508-2 for type A components having a hardware fault tolerance of 0.If the HART multiplexer KFD2-HMM-16 and KFD0-HMS-16 are used together with the module interface as described in section 4.1 then two de-coupling capacitors have to fail to bring the (sub)system into a dangerous state. This corresponds to a hardware fault tolerance of 1.Table 2: KFD2-HMM-16 together with KFD0-HMS-16 with additional module interface T[Proof] = 1 year T[Proof] = 5 years T[Proof] = 10 yearsPFD AVG = 6.13E-08PFD AVG = 3.07E-07PFD AVG = 6.13E-07than 10% of this range, i.e. to be better than or equal to 10-4. The PFD values even fulfill the requirements of a higher SIL but the system does only fulfill the architectural constraints requirements (HFT/SFF) for SIL 3 which are set by table 2 of IEC 61508-2 for type A components having a hardware fault tolerance of 1.Table 3: 2700 HART Signal MultiplexerT[Proof] = 1 year T[Proof] = 5 years T[Proof] = 10 yearsPFD AVG = 2.50E-07PFD AVG = 1.25E-06PFD AVG = 2.50E-06than 10% of this range, i.e. to be better than or equal to 10-4. The PFD values even fulfill the requirements of higher SILs but the system does only fulfill the architectural constraints requirements (HFT/SFF) for SIL 3 which are set by table 2 of IEC 61508-2 for type A components having a hardware fault tolerance of 1.The calculations are based on the assumption that the HART multiplexer are mounted in an environment that is IP 54 compliant (e.g. housing, control cabinet or control room).Table of ContentsManagement summary (2)1Purpose and Scope (5)2Project management (5)2.1Roles of the parties involved (5)2.2Standards / Literature used (5)2.3Reference documents (6)2.3.1Documentation provided by the customer (6)2.3.2Documentation generated by (6)3Description of the HART communication (7)4Description of the analyzed modules (8)4.1KFD2-HMM-16 and KFD0-HMS-16 (8)4.22700 HART Signal Multiplexer (11)5Failure Modes, Effects, and Diagnostics Analysis (12)5.1Description of the failure categories (12)5.2Methodology – FMEDA, Failure rates (12)5.2.1FMEDA (12)5.2.2Failure rates (12)5.2.3Assumption (13)6Results of the assessment (13)6.1KFD2-HMM-16 and KFD0-HMS-16 (15)6.22700 HART Signal Multiplexer (17)7Terms and Definitions (19)8Status of the document (20)8.1Liability (20)8.2Releases (20)8.3Release Signatures (20)1 Purpose and ScopeThis report shall describe the results of the FMEDAs carried out on the HART multiplexer KFD2-HMM-16 together with KFD0-HMS-16 and the 2700 HART Signal Multiplexer.It shall be shown that the HART multiplexer do not electrically interfere with the connected safety related system when using the 4..20mA loop for the HART communication.It shall be assessed whether these modules meet the Probability of Failure on Demand (PFD) requirements for SIL 2 / SIL 3 sub-systems according to IEC 61508 with regard to the interference freeness on the safety related 4..20mA loop.The assessment does neither consider any calculations necessary for proving intrinsic safety nor an evaluation of the correct functioning of the HART multiplexer.Pepperl+Fuchs GmbH contracted in May 2002 with the FMEDA and PFD calculation of the above mentioned modules.2 Project management2.1 Roles of the parties involvedPepperl+Fuchs Manufacturer of the HART multiplexer.

Many device parameters and also the measured values themselves can thus be digitally transferred to and from the device. This digital communication runs in parallel with the 4..20 mA signal on the same cable. This is possible through a current modulation, which is superimposed on the user signal.Figure 1: Modulated HART signalHART is a master-slave protocol: A field device does only respond when requested (except in "Burst mode").The message duration is several hundred milliseconds, so that between two and three messages can be transferred per second.On HART, there are three groups of commands:• The "Universal" commands; these must be supported by all field devices;• The "Common practice" commands; these are pre-defined commands, suitable for many field devices, which, if they are supported by the device, must be implemented in the pre-defined form;• Device-specific commands; these are commands, which are particularly suitable for this field device.1 HART = Highway Addressable Remote Transducer4 Description of the analyzed modulesIn safety-related applications the HART communication is used to provide additional (non safety-related) information about statuses and reading, allow for better preventive maintenance and thus improve the integrity of the field instrumentation.For this purpose the HART multiplexer have to be directly connected to the field wiring of the respective safety-related system (see Figure 2).Figure 2: Connection of the HART multiplexer with the safety-related system4.1 KFD2-HMM-16 and KFD0-HMS-16The HART multiplexer KFD2-HMM-16 can operate up to 256 analog transmitters. The built-in slave unit operates the first 16 loops, and a maximum of further 15 KFD0-HMS-16 slaves can be connected.The power supply (24 VDC nominal voltage) is provided via the power rail or terminals 17 and 18. The optional slave units or the RPI control module are connected with the master via a 14-core flat cable. Its connector is placed on the same housing side as the terminals for the RS 485 interface and the voltage supply.The analog signals for each unit are connected separately via a 26-core cable. 16 leads are provided for the HART signals of the analog instrument circuits, the other 10 are connected to ground.The minimum load resistance of the analog instrument circuits is 230 Ω (min. load resistance in accordance with the HART specification), the max. load resistance is 500 Ω. Load resistances of up to 1000 Ω are possible, however, resistance values greater than 500 Ω can interfere with the HART communication.A process control system or a PC can be connected via a RS 485 interface (terminals 13, 14 and 15). Up to 31 KFD2-HMM-16 can be operated on one RS 485 interface. Terminals 19, 20 and 21 can be used to connect additional stations to the RS 485 interface. The DIP-switch on the housing front is for the setting of the RS 485 address and the baud rate.Figure 3: Block diagram of KFD2-HMM-1626 pin connectorfor up to16 analog signal sources 14 pin connector for up to 15 KFD0-HMS-16 devicesFigure 4: Block diagram of KFD2-HMS-16The HART multiplexer KFD2-HMM-16 (KFD0-HMS-16) has only one de-coupling capacitor for each analog signal as can be seen in Figure 3 and Figure 4, but can be connected to a module interface as shown in Figure 5 to also have the ground de-coupled by a second capacitor. Figure 5: Block diagram HART multiplexer with module interface for loop 1 and 24.2 2700 HART Signal MultiplexerThe Mux2700 HART Multiplexer provides 32 signal channels for connection to “smart” transmitters or control devices supporting digital communication according to the HART standard.Two Decoupling Capacitors are provided, one for each signal connection.Both + Ve (positive) & - Ve (negative) signal wires are therefore decoupled from DC signal. Only the high frequency digital HART protocol signal passes through to the internal Multiplexer circuitry.It acts as a gateway between a workstation - typically a PC - and the field instrumentation.Each Mux2700 is networked simply by connecting the high-speed RS485 output in multidrop configuration. The Mux2700 interrogates each field device, under the supervision of the workstation, retrieving information for storage in its internal database, which can then be accessed at ease.Figure 6: Block diagram of 2700 HART Signal Multiplexer5 Failure Modes, Effects, and Diagnostics Analysis5.1 Description of the failure categoriesThe fail-safe state is defined as the HART multiplexer is not communicating.Failures are categorized and defined as follows:A safe failure (S) is defined as a single failure that causes the HART multiplexer not to communicate.A dangerous failure (D) is defined as a single failure that disturbs the safety system connected to the HART multiplexer.A “don't care” failure (#) is defined as a single failure of a component that is part of the safety function but has no effect on the safety function of the module / (sub)system.5.2 Methodology – FMEDA, Failure rates5.2.1 FMEDAA Failure Modes and Effects Analysis (FMEA) is a systematic way to identify and evaluate the effects of different component failure modes, to determine what could eliminate or reduce the change of failure, and to document the system in consideration.An FMEDA (Failure Mode Effect and Diagnostic Analysis) is an FMEA extension. It combines standard FMEA techniques with extension to identify online diagnostics techniques and the failure modes relevant to safety instrumented system design. It is a technique recommended to generate failure rates for each important category (safe detected, safe undetected, dangerous detected, dangerous undetected, fail high, fail low) in the safety models. The format for the FMEDA is an extension of the standard from MIL STD 1629A, Failure Modes and Effects Analysis.5.2.2 Failure ratesThe failure rate data used by in this FMEDA are from the Siemens SN 29500 failure rate database. The rates were chosen in a way that is appropriate for safety integrity level verification calculations. It is expected that actual field failure results with average environmental stress will be superior to the results predicted by these numbers.The user of these numbers is responsible for determining their applicability to any particular environment. Accurate plant specific data is preferable to general industry average data. Industrial plant sites with high levels of stress must use failure rate data that is adjusted to a higher value to account for the specific conditions of the plant.5.2.3 AssumptionThe following assumptions have been made during the Failure Modes, Effects, and Diagnostic Analysis of the HART multiplexer.• Failure rates are constant, wear out mechanisms are not included.• Propagation of failures is not relevant.• All component failure modes are known.• The repair time after a safe failure is 8 hours.• The average temperature over a long period of time is 40°C.• The stress levels are average for an industrial environment.• All modules are operated in the low demand mode of operation.• Only one communication line is considered to be part of the safety function.6 Results of the assessment did the FMEDAs supported by Pepperl+Fuchs.The analysis has shown that only a couple of components of the HART multiplexer can be found where potentially dangerous failure exist. All other component failures can only lead to the defined safe state but can never disturb the connected safety-related system. The following critical points were identified:1. Short circuits (to ground, to power or between each other) of the signal lines from theinterconnection terminal to the field side of the de-coupling capacitors;2. Short circuit of the de-coupling capacitor.For the calculation of the Safe Failure Fraction (SFF) the following has to be noted:λtotal consists of the sum of all component failure rates. This means:λtotal = λsafe + λdangerous + λdon’t care2SFF = 1 – λdu / λtotalFor the FMEDAs the following failure modes and below mentioned distributions were used. Capacitor fixed plastic (in accordance with [N3])Failure Mode Distribution (in %)Short 40 Open 42 Change in value 182 These are all failures that have no impact on the safety function. The behavior of the system is neither dangerous nor safe.Capacitor Al-ELKO (in accordance with [N3]) Failure ModeDistribution (in %)Short 38 Open 31 Seal failure31For the calculation of the PFD the following Markov models for a 1oo1 and 1oo2 architecture were used. As there are no explicit on-line diagnostics, no state “dd” – dangerous detected is required. As after a complete proof all states are going back to the OK state no proof rate is shown in the Markov models but included in the calculation.The proof time was changed using the Microsoft® Excel 2000 based FMEDA tool of as a simulation tool. The results are documented in the following sections.Figure 7: Markov model for a 1oo1 architectureAbbreviations: d The system has failed dangerous s The system has failed safe λd Failure rate of dangerous failures λs Failure rate of safe failures βCommon cause factor (set to 5%)T Repair Repair time τRepair Repair rate (1 / T Repair )Figure 8: Markov model for a 1oo2 architecture6.1 KFD2-HMM-16 and KFD0-HMS-16Item 1. of the critical points identified in section 6 can be excluded according to draft IEC 60947-5-3 A.1.2 if:• The HART multiplexer are mounted in a housing of minimum IP 54• The base material used is according to IEC 60249, the design and use of the printed board is according to IEC 60326 T3 and the creepage distances and clearances are designed according to IEC 60664-1 (1992) with pollution degree 2 / installation category III, or• The printed side(s) are coated with an insulation material in accordance to IEC 60664-3 (1992)Clearances and creepage distances according to IEC 60661-1 with pollution degree 2 / installation category II for a nominal voltage of 24 VDC are given in Table 4.Table 4: Clearances and creepage distances according to IEC 60661-1Clearances (table 2) Creepage distances (table 4) Printed wiring material 0,1 mm 0,04 mmAccording to Pepperl+Fuchs the base material used is according to IEC 60249 and the minimum creepage distances and clearances are 0,15 mm. This is considered to be sufficient as the interesting distances are part of an energy-consuming equipment supplied from fixed installation, i.e. installation category II. In addition the HART multiplexer is not a safety critical system itself but is connected to one. Thus there are no to special requirements with regard to reliability and availability (see section 2.2.2.1.1 of IEC 60664-1) and installation category III does not apply.Item 2. of the critical points identified in section 6 was analyzed in form of a FMEDA under the assumptions described in section 5.2.3 and 6.The following failure rates and SFF were calculated for the de-coupling capacitor:λtotal = 7,00E-10 1/hλsafe = 2,94E-10 1/hλdangerous = 2,80E-10 1/hλdon’t care = 1,26E-10 1/hSFF = 60,00% (HFT = 0)NOTE: As all faults of the additional electronic will either contribute to λsafe or λdon’t care with regard to the interference freeness on the 4..20mA signal the failure modes of the different components were not explicitly analyzed and are not part of the above mentioned failure rates.The PFD was calculated for three different proof times using the Markov model as described in Figure 7.T[Proof] = 1 year T[Proof] = 5 years T[Proof] = 10 yearsPFD AVG = 1.23E-06PFD AVG = 6.13E-06PFD AVG = 1.23E-05than 10% of this range, i.e. to be better than or equal to 10-3. The PFD values even fulfill the requirements of higher SILs but the system does only fulfill the architectural constraints requirements (HFT/SFF) for SIL 2 which are set by table 2 of IEC 61508-2 for type A components having a hardware fault tolerance of 0.The following figure shows the result of the PFD calculation for T[Proof] = 1 year.Figure 9: PFD for T[Proof] = 1 yearIf the HART multiplexer KFD2-HMM-16 and KFD0-HMS-16 are used together with the module interface as described in section 4.1 then two de-coupling capacitors have to fail to bring the (sub)system into a dangerous state. This corresponds to a hardware fault tolerance of 1.The PFD was calculated for three different proof times using the Markov model as described in Figure 8.T[Proof] = 1 year T[Proof] = 5 years T[Proof] = 10 yearsPFD AVG = 6.13E-08PFD AVG = 3.07E-07PFD AVG = 6.13E-07than 10% of this range, i.e. to be better than or equal to 10-4. The PFD values even fulfill the requirements of a higher SIL but the system does only fulfill the architectural constraints requirements (HFT/SFF) for SIL 3 which are set by table 2 of IEC 61508-2 for type A components having a hardware fault tolerance of 1.The following figure shows the result of the PFD calculation for T[Proof] = 1 year and β = 5% (maximum common cause factor for a logic sub-system according to IEC 61508-6).Figure 10: PFD for T[Proof] = 1 year and β = 5%6.2 2700 HART Signal MultiplexerItem 1. of the critical points identified in section 6 can be excluded according to draft IEC 60947-5-3 A.1.2 if:• The HART multiplexer are mounted in a housing of minimum IP 54• The base material used is according to IEC 60249, the design and use of the printed board is according to IEC 60326 T3 and the creepage distances and clearances are designed according to IEC 60664-1 (1992) with pollution degree 2 / installation category III, or• The printed side(s) are coated with an insulation material in accordance to IEC 60664-3 (1992)Clearances and creepage distances according to IEC 60661-1 with pollution degree 2 / installation category II for a nominal voltage of 24 VDC are given in Table 5.Table 5: Clearances and creepage distances according to IEC 60661-1Clearances (table 2) Creepage distances (table 4) Printed wiring material 0,1 mm 0,04 mmAccording to Pepperl+Fuchs the base material used is according to IEC 60249 and the minimum creepage distances and clearances are 0,25 mm.

In addition the HART multiplexer is not a safety critical system itself but is connected to one. Thus there are no to special requirements with regard to reliability and availability (see section 2.2.2.1.1 of IEC 60664-1) and installation category III does not apply.Item 2. of the critical points identified in section 6 was analyzed in form of a FMEDA under the assumptions described in section 5.2.3 and 6.The following failure rates and SFF were calculated for the two de-coupling capacitors: λtotal = 3,70E-09 1/h λsafe = 1,22E-09 1/h λdangerous = 1,42E-09 1/h λdon’t care = 1,06E-09 1/h SFF = 61,62% (HFT = 1)NOTE: As all faults of the additional electronic will either contribute to λsafe or λdon’t care with regard to the interference freeness on the 4..20mA signal the failure modes of the different components were not explicitly analyzed and are not part of the above mentioned failure rates. As two de-coupling capacitors have to fail to bring the (sub)system into a dangerous state a hardware fault tolerance of 1 is considered.The PFD was calculated based on the failure rate of the Al-ELKO as a worst case assumption for three different proof times using the Markov model as described in Figure 8.T[Proof] = 1 yearT[Proof] = 5 yearsT[Proof] = 10 yearsPFD AVG = 2.50E-07PFD AVG = 1.25E-06PFD AVG = 2.50E-06than 10% of this range, i.e. to be better than or equal to 10-4.
