This is a normal process and not dangerous.•Do not use other chargers than supplied and specified by COMSOFT, the batteries could otherwise be damaged. •Do not use NetTEST II in surroundings with explosion hazard.)In case that water or other liquids should have penetrated your NetTEST II, remove the battery pack or the powersupply adapter. Then have your NetTEST II checked byour Service Department. The same applies for the batterycharging holder and the plug-in battery charger.Introduction 3IntroductionWith the PROFIBUS NetTEST II you have acquired a high-quality tool for the examination of RS485-based PROFIBUSsegments.COMSOFT’s aim is to provide its users with a valuable toolfor an easy check, without extensive test methods of the correctcabling of their PROFIBUS net and to document this.Furthermore, the search for errors in already installedPROFIBUS systems shall be as easy as possible. We guess thatwe reached this target with NetTEST II, the 2nd generation ofCOMSOFT PROFIBUS test tools.Therefore it goes without saying that with NetTEST II, thechecks can be run with connected and disconnected devices. Itdoes not matter if the devices are powered or not. For physicaltesting you only have to ensure that there is no active Master(PLC) polling the bus.Besides the standard cable test, i.e. the verification of the linesregarding cable length, line impedance, correct termination,cable rupture, broken shield, stub lines, inhomogeneouscable segments, mixed up cables, short circuits, faultyPROFIBUS connectors and faulty device connections,NetTEST II disposes of PROFIBUS DP specific testfunctions. So, e.g. the livelist and the Slave Ident Number areindicated, also the transmission level of the Slaves connectedto the bus is detected per device. Furthermore, NetTEST IIdetects the current baud rate at the running bus. During thebaud rate scan a signal analysis indicates faults or errors in thecabling.IntroductionApart from these basic functions the following options are available for NetTEST II:•DP Master OptionWith the DP Master Option the set into operation ofDP Slaves is possible without the PLC. The DP Slavescan be configured with the COMSOFT PROFIBUSconfiguration tool based on the DP Slaves appropriateGSD file.•Online-FunctionThis function performs a detailed analysis of thetelegram traffic and the physical state of thePROFIBUS line.To make installation checks and error retrieval as easy as possible, we divided this manual into the following sections: •Line tests•Menu guide•PC connection•DP Master functionality (optional)•Online functionality (optional)•Tips & TricksWe hope that we can give you with our test tool NetTEST II and this manual all necessary means for a faultless function of your PROFIBUS plant. In case of queries, please contact our hotline, we will be pleased to help you with our advice.LineTests 4Line Tests4.1Line MeasurementGenerally, measurements regarding line physics can only bemade from one end of the PROFIBUS line. If you try tomeasure from any other place within the segment, you willobtain faulty results.Furthermore please make sure that during measurements noMaster is polling the bus or is sending tokens. PurePROFIBUS DP Slave devices as well as e.g. repeaters andoptical couplers must not be disconnected from the bus. Anoversight over the possible measuring points in line segmentsfor line measurement is depicted below:Figure 1: Connection NetTEST II in the cable threadLine Tests4.2Livelist, SlaveDiag, and Level DetectionTo make detections as easy as possible, the generating of the livelist, the Slave diagnosis and Slave-related transmission level detection should be effected as well from the bus end. However, you can also make these from any other available measuring point within one segment. Here, please observe that the function of the livelist and of the SlaveDiag also work via a repeater, segment coupler or optical coupler. The level detection of a Slave connected via such a device reflects only the transmission level of the repeater and not the one of the detected Slaves!4.3Measurement at the running busThe measurements at the running bus are limited to an indication of the current baud rate, as well as of the general transmission level quality of the connected Slaves. By this means, a qualitative evaluation of the level on the bus line is made. If the test tool shows reflections, the reasons for those can only be found with the line detection, which implies that the Master(s) is / are being turned off.NetTEST II Menu Guide 5NetTEST II Menu Guide5.1Start-Up / Setting in OperationCheck the completeness of the scope of delivery and charge batteries before first setting in operation. Remove the battery by gently pressing the locking and at the same time pulling down the battery placed at the rear lower side of the NetTEST II. Now place the battery into the charging holder, and check the loading procedure by means of the LED in the battery charger. For detailed information refer to the enclosed documentation of the battery charger. Remove the battery from the charging holder and push it onto the NetTEST II until you can hear it snapped in.Now push the key approx. 1s, until the PROFIBUS logo appears on the screen. Then release the key. Besides the PROFIBUS logo, the firmware version and date appears for approx. 2s.Figure 2: Screen ‘Start-up’Now the main menu is displayed automatically. The test tool is ready for operation. With various different text outputs the display is too small, this will be indicated by "^^" at the right upper and "vv" at the right lower corner of the text. Bypressing the keys you may scroll up or down in the text.NetTEST II Menu Guide5.2Main MenuThe main menu automatically appears on the display after having started the NetTEST II.Figure 3: Screen ‘Main menu’The main menu comprises the following submenus:•Line Test•Test without PLCStepwise check of cabling and test of DP Slaves,without protocol generation.•PROFIBUS Master mode (optional)Set into operation of DP Slaves without PLC.•Test with PLC (optional)Detailed analysis of the telegram traffic and thephysical state of the PROFIBUS line.•Test Protocol•Test without PLCLike Line Test – Test without PLC, however, theresults of all tests are stored in a test protocol fordocumentation purposes.•Test with PLC (optional)Like Line Test – Test with PLC, however, the resultsof all tests can be stored in a test protocol fordocumentation purposes.•System ConfigurationFor all device-specific settings.•GSD - librarySubmenu for the administration of GSD files.NetTEST II Menu Guide 5.2.1Test without PLCThe menu Test without PLC serves for stepwise physical analysis of lines. This means that the test can be executed as often as desired. Some tests are based on the reference data of the preceding test, so that this one must be run beforehand. The individual items are interlocked, so that wrong operation is impossible. For tests run under this menu, no protocol is made out.Figure 4: Screen ‘Test without PLC’For a line test, at first the design parameters for the PROFIBUS segment that has to be checked must be indicated. These indications are necessary, so that, e.g. the PROFIBUS DP specific measurements at the line segment may be executed with the real bus settings used in your plant. The settings are made in the submenu Segment list.)As soon as a option is activated (DP Master or Online- Function), the Line test menu appears under Testwithout PLC.NetTEST II Menu Guide5.2.1.1Segment listFigure 5: Screen ‘Segment list’Under Segment list, segment-specific data are stored serving as basis for the following measurements. The data are stored in the data base for line segments under the assigned segment name. From there, they can be used as basis for both individual tests and the creation of test protocols. Indications must be made as to the points listed below:•Name of line segment (max. 30 characters) •PROFIBUS baud rate (9.6 Kbit/s - 12 Mbit/s) •PROFIBUS address for master operation of NetTEST II (0-126)•PROFIBUS slot time tslot(300-5000)Figure 6: Screen ‘Segment configuration’NetTEST II Menu Guide The PROFIBUS baud rate, address and slot time are necessary for the parameterization of the installed PROFIBUS Master. With these settings, the tests Generate livelist, Slave ident number, as well as Slave signal quality are executed. Moreover, indications regarding number of:•Connectors (only number of 12 Mbit/s plugs!)•Devices (all devices with PROFIBUS plug, or connected cable)Connected devices and 12 Mbit/s PROFIBUS plugs considerable change by their inductivity resp. capacity the measuring abilities and characteristics for the NetTEST II. In order to keep these measuring insecurities in a tolerable scale, please indicate before each measurement the number of installed 12 Mbit/s plugs as well as the number of the devices connected to the bus. Please only indicate the plugs which dispose of incorporated direct-axis inductances. Devices stands for all units connected to a bus segment. This applies to Master and Slaves as well as to net components like segment couplers, repeaters, optical couplers etc.Once the data are stored in the data base, they can always be used for new tests. The data in this data base cannot be deleted, only changed by overwriting. In order to have enough spare capacity for this function, 20 memory locations are available. The respective memory locations can be reached by actuatingthe or the key.NetTEST II Menu Guide5.2.1.2Test with no terminatorsAt the beginning of each test, the Test with no term. must be carried out. For this, the NetTEST II must be connected to one end of the PROFIBUS segment. Now the user makes sure that all bus termination resistors (terminators) in the bus segment are switched off resp. removed. Furthermore, no Master may send data via the bus. Then the Test with no term. can be carried out. If, by accident, a bus terminator or Master should be active in the segment, the NetTEST II recognizes and indicates this at once. Only if no more resistance in the thread is activated and all Masters are deactivated, the NetTEST II informs about:•Line impedance•Line length (segment length))Detections in segments with PROFIBUS plugs with a disconnection function can be tricky. If, e.g., in the middle of a segment, the terminator of such a plug is activated, the NetTEST II recognizes it, if it is measured from the entrance side. However, if the measurement is made from the other end of the plug, measuring is made into the open end and a cable length, shorter than the one expected, is indicated. Therefore please check very thoroughly if all bus terminators are switched off.Another possibility of finding such a plug is measuring from the other side of the bus.Figure 7: Screen ‘Test with no term’The Test with no term. lasts for a few seconds. The duration depends on the cable length. To show the user that the system is still working, a star bar appears on the lower left hand side of the display as progress indication. Terminate the test with . Upon conclusion the result will be displayed. Attention: If you quit the test with , the Test with 1 term. cannot be executed any more, as the just scanned data were deleted.If no error is detected on the PROFIBUS segment, a "positive acknowledgement" message will appear, displaying the cable impedance and cable length according to the following figure.Figure 8: Screen after ‘Test with no term’The following error indications, that impede correct length and impedance measurement, may occur:•"No error: Impedance not detected": Cable length for the impedance measurement is too short.•"Error: No length measured": Cable length is either too short for length measurement or there is no cable connected.•"Error: A<->shield / B<->shield short circuit": There is a low ohmic resistance between signal wire and shield.•"Error: A<->B Short circuit or unpowered termination": There is a low ohmic resistance between the signal wires, which might be caused for example by a bus termination without power supply.•"Error: A<->B Irregularity, wrong termination or illegal termination ": There is an unacceptable ohmic resistance between the signal wires, that stands in no relation to the magnitude of a bus termination either with or without power supply. The cause might be for example an incorrectly connected bus termination.•"Error: A<->B Terminator": There is a powered bus termination (possibly along the line), which impedes impedance and length measurement.•"Error: A<->shield / B<->shield high imp. fault": There is a high ohmic resistance between signal wire and shield. •"Error: A<->B Capacitive load, junction or Impedance changes": There is a capacitive resistance between the signal wires, which might be caused by a PROFIBUS device with unauthorized bus coupling, a branch or switch over to a inadmissible cable type.•"Error: Possible broken line of shield / of signal line A/B distance XX m": Result of the length measurement is significantly different for the various lines and shields. •"Error: uncertain situation / possibly broken line of shield or of signal line A/B. Please repeat measurement at the opposite segment-end": Result of the cable length measurement for the various different lines and shields is so different, that no specific statement about the respective line segment is possible. Should the measurement on the other line end give correct results, then the measurement may be considered o.k. In particular, this effect may be observed with cable coils or cable drums in the PROFIBUS network.With each of these error messages there may be an indication of a distance. Some errors (e.g. invalid termination) do not give conclusive information about the distance. Moreover, all error messages may also include the indication "uncertain error". This may be indicated, if the cause of the error could be detected only roughly, thus permitting only an error estimation.)Also with uncertain error situations, the PROFIBUS segment has problems in any case, even if themeasured error is relatively small. Due to EMV andhigh baud rates (≥1.5 Mbit) this may lead to severecommunication problems.An effective method for determining errors in theirposition is to divide the segment into several sub-segments, and to submit them to separate examinations.)All error indications are also displayed with the key.5.2.1.3Test with 1 terminatorPrior to the Test with 1 term., in any case the Test with no term. must be completed. If this was not made, the user is being informed about this and can immediately make up for this test. For the Test with 1 term., the terminator at the bus end opposite to the NetTEST II must be switched on and set under current. With a DP Slave unit or another passive bus participant, the plug can be connected directly, the terminator added and the unit switched on. If the unit at the end of the line segment is a PROFIBUS Master, take care that the bus participant does not actively send data onto the bus. This can e.g. be realized by a bus disconnector. Via the bus disconnector, the bus terminator in the PROFIBUS plug is supplied with power, but the bus line is interrupted by a mechanical switch in direction to the line segment.Upon conclusion of the test the result will be displayed on the screen.If no error is detected with the Test with 1 term on the PROFIBUS segment, a "positive acknowledgement" will appear, according to the following figure.Figure 9: Screen after ‘Test with 1 term.'In case of errors, the following error messages may be displayed:•"Error: no termination or switch defect": No valid termination could be detected.•"Error: Your terminator is not at the far end of the segment !": Contrary to the instruction the terminator was switched at the near segment end.•"Error: A<->B twisted": Mix up of signal lines. •"Error: A<->shield / B<->shield short circuit ": There isa low ohmic resistance in the cable between signal wireand shield.•"Error: A<->B short circuit or bus terminal without power supply": There is a low ohmic resistance in the cable between the signal wires.•"Error: A<->B Irregularity, Wrong termination or illegal termination": There is an inadmissible ohmic resistance between the signal wires, that stands in no relation to the magnitude of a bus termination either with or without power supply, for example caused by a wrongly connected bus termination.The Test with 1 term. must also be terminated by the key in order to be able to execute the following test.5.2.1.4Test with 2 terminatorsFollowing the Test with 1 term., the Test with 2 term. is started. Here it is checked if the bus terminator at the line end of the NetTEST II was switched on additionally. For this test, the terminator must also be supplied with power. This can easily be done from the last unit in the segment. If this should be a Master which cannot be made passive, the data line has again to be disconnected from the segment via a bus disconnector.Figure 10: Screen after ‘Test with 2 term.’If the Test with 2 term. was terminated successfully, it can be taken for granted that the cabling in the segment was done correctly. If during the test with NetTEST II an error should has been detected, this would be depicted on the display by a graphic and text indication.Possible error messages are described in detail in chapters 5.2.1.2and 5.2.1.35.2.1.5Generate livelistFigure 11: Screen ‘Generate livelist’In the menu Generate livelist, NetTEST II scans all possible bus addresses from 0....126 for PROFIBUS DP Slave participants. For this, a FDL request is effected several times on each address. If a device answers with OK, its bus address appears on the display. The unit counter is incremented by one. To ensure that also extremely slow units are recognized, the test takes approx. 30 seconds. Should all connected units already be recognized, the user can truncate the test with . Should there be more units than depictable on one display screen, the user can scroll through after the test withkeys.To be able to execute further tests, Generate livelist must by all means be terminated by . Only then the recognized units are registered in the internal memory, so that for these in the following test, a Slave_Diag_Req can be run. If the test is quit by , no slave diagnosis can be executed afterwards!。

网络测试仪,网络分析仪,准确检测profibus DP网络

网络测试仪,网络分析仪,准确检测profibus DP网络

Profibus网络测试仪更多详情,请点击型号:NetTEST IIHightech PROFIBUS Line Analysis由于PROFIBUS DP分区的的错误检测的复杂程度很高,因此分析和测试工具是必不可少的。

使用comsoft NetTEST II分析和测试工具,一个PROFIBUS DP分区能够被系统地测试。

大部分的常见错误,比如安装错误,短路,线缆中断,或者屏蔽中断能够在实际操作之前被检测和解决——不管DP从站是连接还是断开,是通电还是断电。

在每一个PROFIBUS DP分区的始端或者末端,通过NetTEST II进行检修有以下三个步骤:1、不带端接器测试:两个总线端接器都必须关闭。

2、带一个端接器测试:在远程总线端的总线端接器必须打开和通电。

3、带两个端接器测试:两个总线端接器都必须打开和通电。

为防止第二个总线端接器是通过PLC(profibus 主站)上电的,包含在发送包的总线隔离开关能够用以切断信号线。

NetTEST II能够检测和准确找出以下错误:◆两根信号线A和B之间的短路◆信号线A或者信号线B以及屏蔽情况◆线缆中断或者屏蔽中断◆交叉的信号线A-B◆不准确的或者丢失的总线端接器◆总线端接器的错误位置◆不允许的线缆长度◆错误的总线电缆波阻抗◆错误类型的电缆◆不够高的传送和接收级别◆不允许的支线◆反射可以设置不同的灵敏度级别,甚至是毫伏级。

因此,由于多重接地屏蔽引起的最小的反射也能够被测出。

如果最高灵敏度级别也显示无误,那么关于屏蔽或者导线束中断的安装会是最高质量的。

另外,NetTEST II也能生成一个从站列表,这个列表提供了所有可操作的DP从站的识别号,并可评估RS485接口的传输电平。

与PLC的一般操作中,传输和接收电平能够被检查是否不可接收或者有反射,并且实际的波特率也能被显示出来。

所有的结果都能归档在一个详细的测试记录中。

这包括,比如,一组检验和,这组检测和能够使其在操作时与测试记录做核对。

应用层网络设备性能评估与测试方法

应用层网络设备性能评估与测试方法

目录1. 传统网络层性能指标不适合应用层 (2)2. 网络层性能指标回顾 (2)2.1RFC对网络设备性能的定义 (2)2.2吞吐量是网络层性能的首要指标 (4)3. 应用层性能指标 (4)3.1应用层网络设备特点 (4)3.2NSS Labs对应用层性能的定义 (5)3. 小结 (7)4. 应用层性能测试方法 (7)4.1逼近“真实世界”的流量模型 (7)4.2应用层性能指标与测试方法 (8)5. 结论 (9)6. 关于网康科技 (10)1.传统网络层性能指标不适合应用层用户对网络业务的可视性、可管理性要求越来越高,要求能从业务视角理解网络流量,并针对应用制定管理策略。

因此近十年来,各种创新的应用层网络产品雨后春笋般涌现出来,比如上网行为管理、智能流量管理、Web应用防火墙(WAF)等,下图为某运营网络的流量走势图,通过以网络应用而非传统的TCP/UDP对流量分类,可以更直观地看到流量的构成与分布。

另外,传统的网络层安全产品也在向应用层安全设备演进,如传统防火墙、IPS,由于缺乏应用识别与控制能力,正在被面向应用层的下一代防火墙(NGFW)、下一代IPS 产品取代。

某运营网络流量走势性能是网络设备选型必须考虑的因素,目前通用的性能指标和评估方法都是基于网络层的,不适合应用层的特点。

由于缺乏相应标准,业内仍普遍以网络层性能参数来衡量应用层性能,这既不利于用户选型使用,也不利于产品规划发展。

因此很有必要讨论适合应用层特点的网络设备性能指标与评估方法。

2.网络层性能指标回顾2.1RFC对网络设备性能的定义传统网络设备性能标准主要来源于3个RFC文档:RFC1242,RFC2544和RFC3511。

其中,RFC1242定义了网络性能基准测试及测试结果用到的基本术语,最重要的4个是:吞吐量,丢包率,延迟,背靠背。

RFC2544对上述性能评测参数的具体测试方法、结果提交形式作了较详细的规定。

RFC3511详细描述了防火墙设备的测试标准与方法,对RFC2544中的指标如何测试提供了更详细的指导。

of reci-procity compared with purely random network with the same number of vertices and edges.The useful information from reciprocity is not the value itself,but whether mutual links occur more or less often than expected by chance.To overcome this issue,reciprocity can be defined as the correlation coefficient between the entries of the adjacency matrix of a directed graph:i=j (a ij−a )((a ji−a )i=j(a ij−a )2where a’is the density of g.This definition gives an absolute quantity which directly allows one to distinguish between recip-rocal(>0)and antireciprocal(<0)networks,with mutual links occurring more and less often than random respectively.ValueReciprocity as a correlationAuthor(s)David SchochReferencesDiego Garlaschelli;Loffredo,Maria I.(2004)."Patterns of Link Reciprocity in

《NetTEST II 选型指南》
众所周知,作为一款高性能的 Profibus 诊断分析仪,NetTEST II 可以全面的协助工程 师检测 Profibus 网络故障,分析 Profibus 网络性能。

无论在调试、安装过程还是在后期排 查故障和分析网络。

NetTEST II 都能对网络进行全面的故障排查和性能分析, 可谓 Profibus 故障排查的“专家” 。

NetTEST II 可进行 Profibus 网络的物理层的检测;也可实现 Online 功能,检测一个正 在运行的 Profibus 网络;同时,NetTEST II 也可做 DP 单主站进行,进行移动调试从站。

以下结合 NetTEST II 的功能和工程师们所需进行简单量体裁衣。


一、
NetTEST II 物理层检测 Profibus 网络:
             信号线路 A 和 B 之间的短路,显示精确距离(以米为单位) 信号线路 A 或 B 和屏蔽之间的短路,显示精确距离(以米为单位) 线路或屏蔽破裂,显示精确距离(以米为单位) 相互交换的信号线路 A-B 不正确或缺少总线端电阻 总线端电阻的错误位置 不允许的线路长度 总线线路的错误波阻抗 电缆的错误类型 反射 发送或接收水平差 不允许的支线路 NetTEST II 通过键盘和全图形化 LCD 显示屏操作。

它可通过 COM 口和配套的电 缆可连接到电脑。


各种线路测试
全面的错误报告
状态分析


二、
NetTEST II 在线功能(Oline) :
NetTEST II 可用在一个运行中的 PROFIBUS 系统。

在这种情况下,NetTEST II 工作在一个全面的被动 监测模式,并且对数据通讯进行一个全面分析,也包括 PROFIBUS 线路的物理状态。

DP 从站状态分析
每个 DP 从站的通讯状态对于一个 DP 网络正常工作至关重要。

从站偶发性地失效会减 DP 少网络的吞吐量并且常常会导致整个系统瘫痪。

NetTEST II 测试 DP 主站和 DP 从站之间 的数据通讯,并且显示每个 DP 从站通讯状态的所有变化。

因此,一个 DP 网络可在长期 工作期间监测其特定变化。

没有配置的 DP 从站,仍然是在线设备列表的一部分,也可以 显示在 DP 主站上。


事件触发
事件触发功能可全面测试故障 DP 从站。

另外,事件触发能够提供单个事件的详细分析, 例如一个诊断报文。


波特率扫描
NetTEST II 可探测运行着的 PROFIBUS 的当前波特率。

在波特率扫描期间,PROFIBUS 上的全部信号水平都被测量和测试。


DP 网络的循环时间
NetTEST II 可计算 DP 主站轮询所有配置的 DP 从站一次所需要的时间。

所测量的最大和 最小值被保存和显示。

循环时间能够明确显示性能问题,例如,处于间歇性故障的 DP 网 络。

另外,循环时间显示 PROFIBUS 网络是否满足所有系统要求,因为循环时间必须在 任何情况下都要低于所要求的系统反应时间。


在线设备列表
NetTEST II 检测总线通讯并且生成一个活列表包含网络上所有的有源主站和从站。

每个 DP 从站的水平显示 NetTEST II 显示每个独立 DP 从站的 RS485 驱动输出水平, 以条形图 的形式显示。

所测量的水平和名义范围的任何偏差都表示有严重的 PROFIBUS 网络问题。

所有在线测试结果都保存在一个测试协议中,可复制到电脑。


生成在线设备列表
信号水平测量
移动调试


三、
DP 单主站功能
NetTEST II 是一款移动调试 DP 从站的超级工具
整个 PROFIBUS 网络可设置为不用 PLC 就能工作,例如所连接的 DP 从站的 I/O 数据可轻松 地可视化和修改,因此可有效测试所连接的传感器/执行器技术。

PROFIBUS 诊断数据被分解 并在与系统、模块和通道相关的独立位置显示,并且符合相应的标准。

可在 NetTEST II 上直接 配置不同的 DP 从站或者用配套的 PROFIBUS 配置软件在电脑上配置。

该配置软件包含在发货 清单内。
