现场总线技术是在市场对现场仪表智能化以及全数字控制系统的需求驱动下产生的。

从技术的角度看，则是计算机技术、网络技术和控制技术发展的必然产物。

现场总线的关键标志是它能支持双向、多变量、总线式的全数字通信。

现场总线技术的出现，必将冲击现有过程控制系统的技术知识、设计方法、安装调试方法、人员培训以及产品市场的格局。

为了在这次变革中不至于被抛在后面，不同国家、不同厂商纷纷组成集团，发表各自的现场总线标准，以图率先占领市场。

比较主要的现场总线标准有Profitbus、CAN、Lonworks、SP50、ISPFIP和HART等，但由于受各自利益驱动和市场竞争，现场总线国际标准的制定进展缓慢。

§1.2 HART协议的发展虽然现场总线发展迅速，但由于4~20mA信号制的模拟设备还在大量使用中，因此从4~20mADC信号转变为现场总线全数字通讯并非一蹴而就，预计这一转变需要几十年时间。

H owever, developers,manufacturers and users of the HART compatible devices can be assured that fundamental HART principles are maintained. H ART 6 is backward compatible with H ART 5 while increasing the capabilities of 4-20mA devices and systems. New commands have been added, and bytes added to several commands. HART 5 masters should work with HART 6 slaves and vice versa. Obviously,the H ART 5 master cannot take advantage of H ART 6 features, but an immediate wholesale replacement of control systems and field devices is not the objective of the Protocol. For example,an older I/O system that supports only 25Byte H ART Commands cannot issue the 32Byte Long Tag Commands.In this specification six new commands have been added and bytes are added to several commands:1. Three new commands support a new 32 byte, ISO Latin-1 Long Tag. The commands readand write the Long Tag and an Identity Command supports polling via the Long Tag.Identity Commands and their use is explained in the Command Summary Specification.2. Two bytes are added to the Identity Commands indicating the number of response preamblesand the number of Device Variables. The number of Device Variables has long been desiredby master applications.3. Polling address support is enhanced. In addition, the Loop Current is now allowed to beactive at polling addresses other then zero. For example:• This allows series connections of actuators implementing a split range capability.• The increasing use of transmitters connected in series with actuators is now directly supported allowing the embedding of PID controllers in field devices.A new command is added to allow the configuration of the loop to be read.4. Cyclical data acquisition has long been an under-utilized strength of HART. Support fordigital process readings is enhanced through the addition of Command 9 which supplies astatus byte for each process reading returned. The Command Summary Specificationdescribes the function of this status byte.5. A command is added that allows the Device Variable Classification for each Dynamic Variableto be read and allows for Engineering Unit Code Expansion.These additions are valuable in many applications. H owever, the changes are incremental enhancements that do not fundamentally change the Protocol.HART Communication Foundation Document Number: HCF_SPEC-127Document Title: Universal Command SpecificationIn addition to functional changes, the document as a whole has been reformatted to include new sections: Preface, Introduction, Scope, References, Definitions, Symbols/Abbreviations, and Data Format. The additional sections and the new format improves the clarity and consistency of the Specifications.Revision 6.0, Release Date: 18 April, 2001Page 6 of 44HART Communication Foundation Document Number: HCF_SPEC-127Document Title: Universal Command SpecificationRevision 6.0, Release Date: 18 April, 2001Page 7 of 44IntroductionThe Univ ersal Command Specification is a key document in the HART Specifications as it establishes the minimum Application Layer support required of all HART Devices. In fact, the Universal Command Specification is considered so important that the major revision level of the entire Protocol always matches the major revision level of this document.H ART is a master-slave protocol and is loosely organized around the ISO/OSI 7-layer model for communications protocols (see Figure 1). The Application Layer is the topmost layer in the Open System Interconnect (OSI) model. More H ART specification documents address the ApplicationLayer than any other OSI Layer.Figure 1. OSI 7-Layer ModelThe Application Layer in HART defines the commands, responses, data types and status reporting supported by the Protocol. In addition, there are certain conventions in HART (for example how to trim the loop current) that are also considered part of the Application Layer. While the Command Summary, Common Tables and Command Response Code Specifications all establish mandatory Application Layer practices (e.g. data types, common definitions of data items, and procedures), the Universal Commands specify the minimum Application Layer content of all HART compatible devices.HART Communication Foundation Document Number: HCF_SPEC-127Document Title: Universal Command SpecificationRevision 6.0, Release Date: 18 April, 2001Page 8 of 44HART Communication Foundation Document Number: HCF_SPEC-127Document Title: Universal Command Specification1.SCOPEThis document is an Application Layer specification and, as a result, builds on the Application Layer requirements found in the Command Summary Specification. Conformance to the Universal Command Specification requires Command Summary Specification conformance as a prerequisite. This document supersedes all previous revisions of the Universal Command Specification.The Univ ersal Command Specification contains definitions of all H ART Protocol Universal Commands. HART compatible devices must implement all universal commands exactly as described within this specification. Many Universal Commands refer to tables from the Common Tables Specification. When Common Tables are referenced, data from the tables must be used exactly as specified.2.REFERENCES2.1The HART-Field Communications Protocol SpecificationsThese documents published by the H ART Communication Foundation are referenced throughout this specification:HART Field Communications Protocol Specification.

For more information about these formats refer to the Command Summary Specification. Bits Each individual bit in the byte has a specific meaning. Only values specified by the command may be used. Bit 0 is the least significant bit.Date The Date consists of three 8-bit binary unsigned integers representing, respectively, the day, month, and year minus 1900. Date is transmitted day firstfollowed by the month and year bytes.Enum An integer enumeration with each numeric value having a specific meaning. Only values specified in the Common Tables Specification may be used.Float An IEEE 754 single precision floating point number. The exponent is transmitted first followed by the most significant mantissa byte.Latin-1 A string using the 8-bit ISO Latin-1 character set. Latin-1 strings are padded out with zeroes (0x00).Packed A string consisting of 6-bit alpha-numeric characters that are a subset of the ASCII character set. This allows four characters to be packed into three bytes.Packed ASCII strings are padded out with space (0x20) characters.Unsigned-nn An unsigned integer where nn indicates the number of bits in this integer. Multi-byte integers are transmitted MSB — LSB.MANDS6.1Command 0 Read Unique IdentifierThis is an Identity Command (see the Command Summary Specification).Returns identity information about the field device including: the Device Type, revision levels, and Device ID. This command is implemented by a field device in both Short and Long Frame Formats. Command 0 is the only command that may respond to a short frame address.The combination of Manufacturer ID, Device Type, and Device ID make up the Unique ID used to construct the long frame address. No two devices ever manufactured may have the same combination of these three data.The Configuration Change Counter must be incremented once for every command received that changes the devices configuration. The counter must also be incremented once for every user action that changes the device’s configuration or calibration (e.g., from a local operator interface). This value is never reset or written and must be maintained, even if power is removed from the device or a device reset is performed.Request Data BytesByte Format DescriptionNoneResponse Data BytesByte Format Description0Unsigned-8"254"1 Enum Manufacturer Identification Code (see Common Table 8,Manufacturer Identification Codes)2 Enum Device Type (refer to the Command Summary Specificationand the Data Link Layer Specification)3Unsigned-8Minimum number of Preambles required for the requestmessage from the Master to the Slave.

The Upper and Lower Range Values map the Loop Current Value to the Percent of Range. As a result the Percent of Range is not limited to values between 0% and 100%, but tracks the Loop Current to Transducer Limits when they are defined.Request Data BytesByte Format DescriptionNoneResponse Data BytesByte Format Description0-3Float Primary Variable Loop Current (units of milli-amperes)4-7Float Primary Variable Percent of Range (units of percent) Note:Voltage Mode Field Devices use "Volts DC" as their engineering unitsCommand-Specific Response CodesCode Class Description0Success No Command-Specific Errors1-5Undefined6Error Device-Specific Command Error7Undefined8Warning Update Failure9-15Undefined16Error Access Restricted17-127Undefined6.4Command 3 Read Dynamic Variables And Loop CurrentReads the Loop Current and up to four predefined Dynamic Variables. The Loop Current always matches the current that can be measured by a milli-ammeter in series with the field device; this includes alarm conditions and set values.The Response Data is truncated after the last Dynamic Variable supported by each Device Type (see Table 1). For a given Device Type the number of Response Data bytes must be fixed. In other words, a Device type may not return PV, SV, and TV in one operating mode and later (in a different operating mode) only return PV and SV.Table mand 3 Response Based on Number of DynamicVariables Supported.Dynamic Variables Supported No. of Response DataBytesPV9PV, SV14 PV, SV, TV19 PV, SV, TV, QV24Request Data BytesByte Format DescriptionNoneResponse Data BytesByte Format Description0-3Float Primary Variable Loop Current (units of milli-amperes)4 Enum Primary Variable Units Code (refer to Common TablesSpecification)5-8Float Primary Variable9 Enum Secondary Variable Units Code (refer to Common TablesSpecification)10-13Float Secondary Variable14 Enum Tertiary Variable Units Code (refer to Common TablesSpecification)15-18Float Tertiary Variable19 Enum Quaternary Variable Units Code (refer to Common TablesSpecification)20-23Float Quaternary VariableNote Voltage Mode Field Devices use "Volts DC" as their engineering units for "Loop Current" rather then milliampsCommand-Specific Response CodesCode Class Description0Success No Command-Specific Errors1-5Undefined6Error Device-Specific Command Error7Undefined8Warning Update Failure9-15Undefined16Error Access Restricted17-127Undefined6.5Command 4 ReservedRevisions 3 and 4 of this document included this command. These commands must not be implemented in any field device.6.6Command 5 ReservedRevisions 3 and 4 of this document included this command. These commands must not be implemented in any field device.6.7Command 6 Write Polling AddressThis is a Data Link Layer Management Command.This Command writes the polling address and the loop current mode to the field device. The polling address is used for automatic master identification of field devices. The loop current mode determines whether current signaling is being used by the field device.Masters claiming compatibility with this revision of the specification must always supply the all request data bytes.All Field Devices must be able to operate in multi-drop with loop current signaling disabled. When current signaling is disabled, the loop current is set to the minimum value required for field device operation. The field device status bit 3, Loop Current Fixed, is set, and, if appropriate, the Upscale/ Downscale Alarm is disabled. Furthermore, commands that affect the Loop Current must not be executed while loop current signaling is disabled. These include:•Command 40 Enter/Exit Fixed Current Mode;•Command 45 Trim Loop Current Zero; and•Command 46 Trim Loop Current Gain.These Commands shall return Command-Specific Response Code 11, In Multidrop Mode, while loop current signaling is disabled . In addition,•Command 66 Enter/Exit Fixed Analog Output Mode;•Command 67, Trim Analog Output Zero; and•Command 68, Trim Analog Output Gainshall return Command-Specific Response Code 11, In Multidrop Mode, when Analog Channel 0 is selected and loop current signaling is disabled.All Field Devices should be manufactured with the polling address set to a default value of zero (0) and the loop current mode set to active. This ensures HART field devices will operate in place of an analog-only field device by default.6.7.1Backward Compatibility RequirementsField devices receiving Command 6 with a single data byte must: (1)assume the Master is HART Revision 5; (2)enable current signaling if the polling address is zero; (3)disable current signaling if the polling address is non-zero and (4)answer providing both the polling address in the master request and the appropriately set Loop Current Mode byte.When a field device receives a single request data byte, it must answer the master request without returning Response Code 5, Too Few Data Bytes Received.Request Data BytesByte Format Description0 Unsigned-8 Polling Address of Device (refer to the Data Link LayerSpecification)1Enum Loop Current Mode (refer to Common Table 16, LoopCurrent Modes)Response Data BytesByte Format Description0 Unsigned-8 Polling Address of Device (refer to the Data Link LayerSpecification).1Enum Loop Current Mode (refer to Common Table 16, LoopCurrent Modes)Command-Specific Response CodesCode Class Description0Success No Command-Specific Errors1Undefined2Error Invalid Poll Address Selection3-4Undefined5Error Too Few Data Bytes Received6Error Device-Specific Command Error7Error In Write Protect Mode8-11Undefined12Error Invalid Mode Selection13-15Undefined16Error Access Restricted17-31Undefined32Error Busy33-127Undefined6.8Command 7 Read Loop ConfigurationRead polling address and the loop current mode.Request Data BytesByte Format DescriptionNoneResponse Data BytesByte Format Description0Unsigned-8Polling Address of Device (refer to the Data Link LayerSpecification)1Enum Loop Current Mode (refer to Common Table 16, LoopCurrent Modes)Command-Specific Response CodesCode Class Description0Success No Command-Specific Errors1-15Undefined16Error Access Restricted17-127Undefined6.9Command 8 Read Dynamic Variable ClassificationsReads the Classification associated with the Dynamic Variables.

hart命令举例-回复Hart命令是一种用于计算机系统中的命令行工具。

它可以用于执行各种系统管理任务，包括文件和目录操作、进程管理、网络设置等。

在本文中，我们将以“网络设置”作为主题，介绍一些Hart命令的使用方法。

Hart命令可以帮助我们轻松地配置和管理网络设置，包括IP地址、子网掩码、网关、DNS等。

以下是几个常用的Hart命令示例，用于展示如何使用这些命令来设置和管理网络。

1. 查看网络配置：首先，我们可以使用“hart ip show”命令来查看当前系统的网络配置。

打开命令行接口，并输入以下命令：hart ip show这个命令将显示当前系统的IP地址、子网掩码和网关信息。

通过查看这些信息，我们可以了解当前网络的配置情况。

2. 配置网络接口：如果我们希望配置网络接口，例如更改IP地址或子网掩码，可以使用“hart ip set”命令。

以下是一个示例：hart ip set eth0 address 192.168.0.100hart ip set eth0 netmask 255.255.255.0这个命令将更改eth0网络接口的IP地址为192.168.0.100，并将子网掩码设置为255.255.255.0。

我们可以根据需要修改这些值。

3. 配置默认网关：如果我们需要配置系统的默认网关，可以使用“hart route”命令。

以下是一个示例：hart route add default gateway 192.168.0.1这个命令将设置系统的默认网关为192.168.0.1。

通过设置默认网关，我们可以确保系统在与外部网络通信时能够正确路由数据。

4. 配置DNS服务器：如果我们需要配置DNS服务器，可以使用“hart dns set”命令。

以下是一个示例：hart dns set nameservers 8.8.8.8 8.8.4.4这个命令将设置系统的DNS服务器为8.8.8.8和8.8.4.4。

确认键：用于各菜单的选取和数字信息的选取。

修改键：用于对仪表的数据信息的修改。

背光键：用于背光的打开与关闭。

电源键：用于电源的打开与关闭。

退出键：用于各项菜单的退出。

功能键：用于扩展功能(待用)。

特定功能键：向上光标移动键：用于在监测“过程变量”中的退出。

二、连接所需仪器：一台智能变送器；一台HART手持式操作通信器(简称:手操器)；一台12～45VDC电源；一个大于或等于250欧的负载电阻；一台精密毫安表或毫伏表；一台标准精密压力计（压力计精度至少比变送器高3倍）。

连接如下图所示：变送器线性化安装图注：为保证可靠通信，请将负载电阻串联在电源的正极。

三、主菜单按下面板中“电源开/关”按键，单点通讯将出现HART手操器主菜单。

如右轮询通讯图1所示：“单点通讯”在“零号地址码”可使用，若仪表的地址码不为“零号”，则应用“轮询通讯”方式通讯。

菜单中的“▋”为需要选择的图1 主菜单选项。

按“确认”按键进入在线调试状态（图2）四、在线调试状态在线调试状态是一个设置的窗口，主要包括七部分组成，如下图2中所示。

可根据用户的需要进行不同的读取与设置。

各个选项的具体操作说明在下面各章节中详细说明。

1、过程变量 如右图3所示。

本选项可以查看仪表的“PV ”（压力）、“I ”（电流）、“PER ”（百分数值）、“T ”（环境温度）、“LRV ”（零位）、“URV ”（ 量程）、“LSL ”（最大测量范围低限）、“USL ”（最大测量范围高限）。
