D Converts Light Intensity to Digital Signal D Infrared Compensation to ApproximateHuman Eye ResponseD Companding A/D for Wide Dynamic Range D Rejects 50 Hz/60 Hz Lighting Ripple D Two-Wire SMBus Serial InterfaceD Single Supply Operation (2.7 V to 5.5 V)D Low Active Power (1 mW typ)D Power Down ModeDLow-Profile Surface-Mount PackageDescriptionThe TSL2550 is a digital light sensor with a two-wire, SMBus serial interface. It combines two photodiodes and a companding analog-to-digital converter (ADC) on a single CMOS integrated circuit to provide light measurements over an effective 12-bit dynamic range.The TSL2550 is designed for use with broad wavelength light sources. One of the photodiodes (Channel 0) is sensitive to visible and infrared light, while the second photodiode (Channel 1) is sensitive primarily to infrared light. An integrating ADC converts the photodiode currents to Channel 0 and Channel 1 digital outputs. Channel 1 digital output is used to compensate for the effect of the infrared component of ambient light on Channel 0digital output. The ADC digital outputs of the two channels are used to obtain a value that approximates the human eye response in the commonly used unit of Lux.This device is intended primarily for use in applications in which measurement of ambient light is used to control display backlighting such as laptop computers, PDAs, camcorders, and GPS systems. Other applications include contrast control in LED signs and displays, camera exposure control, lighting controls, etc. The integrating conversion technique used by the TSL2550 effectively eliminates the effect of flicker from AC-powered lamps, increasing the stability of the measurement.8 SMBData 7 NC 6 NC 5 SMBCLKPACKAGE D 8-LEAD SOIC (TOP VIEW)V DD 1NC 2NC 3GND 4Terminal FunctionsAvailable OptionsAbsolute Maximum Ratings over operating free-air temperature range (unless otherwise noted)†. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Supply voltage, V DD (see Note 1) 6 V Digital output voltage range, V O–0.3 V to +6 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Digital output current, I O±10 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .SMBus input/output current, I(SMBIN)–1 mA to 20 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Operating free-air temperature range, T A –25°C to 85°C. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Storage temperature range, T stg –25°C to 85°C. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .ESD tolerance, human body model 2000 V †Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

At the end of the conversion cycle for each channel (approximately 400 ms), the conversion result is transferred to the appropriate channel 0 or channel 1 ADC register. The transfer is double-buffered to ensure that invalid data is not read during the transfer. After the data is transferred, the TSL2550 automatically begins the next conversion cycle. Approximately 800 ms is required for both Channel 0 and Channel 1 ADC registers to be updated. A VALID bit is used to indicate that data has been written to the ADC register after ADC is enabled.Interface to the ADC and control of other device functions is accomplished using the standard 2-wire System Management Bus (SMBus) interface. Both versions 1.1 and 2.0 of the SMBus are supported.Digital InterfaceThe TSL2550 contains an 8-bit command register that can be written and read via the SMBus. The command register controls the overall operation of the device. There are two read-only registers that contain the latest converted value of each of the two ADC channels. The SMBus slave address is hardwired internally as 0111001 (MSB to LSB, A6 to A0).Both the send byte protocol and the receive byte protocol are implemented in the TSL2550. The send byte protocol allows single bytes of data to be written to the device (see Figure 6). The written byte is called the COMMAND byte. The receive byte protocol allows single bytes of data to be read from the device (see Figure7). The receive data can be either the previously written COMMAND byte or the data from one of the ADCchannels.S = Start Condition P = Stop Condition Shaded = Slave TransmissionFigure 6. Send Byte ProtocolS = Start Condition P = Stop Condition Shaded = Slave TransmissionFigure 7. Receive Byte ProtocolCommand RegisterThe command register contains eight bits as described in Table 1 and defaults to 0 (0x00) at power-up. A command summary appears in Table 2.Table 1. Command Register Data FormatThe command register is used primarily to select which register will be read during a read cycle (RSEL) and to control the power consumption of the device (ADCEN and PON). When ADCEN and PON are high, the device is in the full powered-up state and is fully operational. When ADCEN and PON are low, both the ADC and the internal oscillator are powered down, resulting in minimum power consumption. Both ADCEN and PON should always be asserted and de-asserted together. The remaining bits (B4, B3, and B2) in the command register should always be written 0. For details on using the command register, see the Operation section, below.Table 2. Command SummaryADC RegisterThe TSL2550 contains two ADC registers (channel 0 and channel 1). Each ADC register contains two components to determine the logarithmic ADC count value: CHORD bits and STEP bits. The CHORD bits correspond to the most significant portion of the ADC value and specifies a segment of the piece-wise linear approximation. The STEP bits correspond to the least significant portion of the ADC count value and specifiesa linear value within a segment. CHORD and STEP bits all equal to 0 corresponds to a condition in which thelight level is below the detection limit of the sensor. CHORD and STEP bits all equal to 1 corresponds to an overflow condition.Each of the two ADC value registers contain seven bits as described in T able 3. The specific ADC value register read depends on the last written RSEL field to the command register, as described above and in the Operation section, below.Table 3. ADC Register Data FormatThe MSB of the ADC register (VALID bit B7) is used to indicate that data has been written to the ADC register after the ADC and internal oscillator are activated as described in Command Register section.Bits 6 through 0 contain the 7-bit code representing the ADC count value, which is proportional to a photodetector current. In this code, the ADC count value is represented by a piece-wise linear approximation to a log function. The transfer function is broken into 8 chords of 16 steps each. (This code is very similar to µ-law code used in audio compression — it differs in that it does not have a sign bit and it is not inverted.) T able 4 shows the relationship between the CHORD and STEP bits and the CHORD and STEP numbers and values. These are used to calculate the ADC count value.Table 4. CHORD and STEP Numbers and Values vs Register BitsNOTES: A.CHORD VALUE = INT (16.5 × ((2C) – 1))B.STEP VALUE = 2CThe ADC count value is obtained by adding the CHORD VALUE and the product of the STEP NUMBER and STEP VALUE (which depends on CHORD NUMBER).ADC Count Value+((Chord Value))(Step Size)(Number of Steps)) The ADC count value is as a formula:ADC Count Value+(INT(16.5((2C*1))))(S(2C))where:C is the CHORD NUMBER (0 to 7)S is the STEP NUMBER (0 to 15)as defined in Table 4.OperationAfter applying VDD, the device will initially be in the power down state. To operate the device, issue an SMBus Send Byte protocol with the device address and the appropriate command byte to read ADC channel 0 or ADC channel 1 (see T able 2). T o obtain the conversion result, issue an SMBus Receive Byte protocol with the device address. The data byte received will correspond to the value in the ADC register (0 or 1) specified by the previous command. If a conversion has not been completed since power up (either through V DD or ADCEN/PON), the valid bit will be 0, and the data will not be valid. If there is a valid conversion result available, the valid bit will be set (1), and the remaining 7 bits will represent valid data from the previously selected ADC register. Data may be read repeatedly from the currently selected ADC register, and although it will remain valid, the ADC register will not be updated until a new conversion completes for that channel (800 ms total since there are two serial 400 ms per channel conversion times). Note also that the command register itself may be read, as a check to be sure that the device is communicating properly.To power down the device for reduced power consumption, issue an SMBus Send Byte protocol with the device address followed by 0 to clear the ADCEN and PON bits.APPLICATION INFORMATIONThe TSL2550 is intended for use in ambient light detection applications, such as display backlight control, where adjustments are made to display brightness or contrast based on the brightness of the ambient light, as perceived by the human eye. Conventional silicon detectors respond strongly to infrared light, which the human eye does not see. This can lead to significant error when the infrared content of the ambient light is high, such as with incandescent lighting, due to the difference between the silicon detector response and the brightness perceived by the human eye.This problem is overcome in the TSL2550 through the use of two photodiodes. One of the photodiodes (Channel0) is sensitive to both visible and infrared light, while the second photodiode (Channel 1) is sensitive primarilyto infrared light. An integrating ADC converts the photodiode currents to Channel 0 and Channel 1 digital outputs. Channel 1 digital output is used to compensate for the effect of the infrared component of light on the Channel 0 digital output. The ADC digital outputs from the two channels are used in a formula to obtain a value that approximates the human eye response in the commonly used Illuminance unit of Lux:Light Level(lux)+(Ch0Counts)(0.46)(e(*3.13R))where:R = (Ch1 Counts) / (Ch0 Counts)The formula above was obtained by optical testing with fluorescent and incandescent light sources. The light level calculated from the formula will be slightly higher than the actual light level for sunlight and will be slightly lower than the actual light level for composite fluorescent and incandescent light sources.Table 5 contains a summary of the typical sensor outputs for several common light sources.Table 5. Sensor Output SummaryLight from 50 or 60 Hz sources, and especially fluorescent lighting, has a high harmonic content. Since the TSL2550 integrates the ambient light over an approximately 400 millisecond interval (per channel), this light ripple is typically reduced to less than ¼ LSB.Power Supply DecouplingThe power supply lines must be decoupled with a 0.1 µF capacitor placed as close to the device package as possible. The bypass capacitor should have low effective series resistance (ESR) and effective series inductance (ESI), such as the common ceramic types, which provide a low impedance path to ground at high frequencies to handle transient currents caused by internal logic switching.MECHANICAL DATAPACKAGE DPLASTIC SMALL-OUTLINEDETAIL AA2y 6y 1.8 +NOTES: A.All linear dimensions are in millimeters.B.Package is molded with an electrically nonconductive clear plastic compound having an index of refraction of 1.55.C.Actual product will vary within the mechanical tolerances shown on this specification.

DCS和PLC的区别

DCS和PLC的设计原理区别较大，PLC是从摸仿原继电器控制原理发展起来的，70年代的PLC只有开关量逻辑控制。

它以存储执行逻辑运算、顺序控制、定时、计数和运算等操作的指令；并通过数字输入和输出操作，来控制各类机械或生产过程。

用户编制的控制程序表达了生产过程的工艺要求。

将其存入PLC的用户程序存储器，运行时按存储程序的内容逐条执行，以完成工艺流程要求的操作。

DCS是在运算放大器的基础上得以发展的。

把所有的函数、各过程变量之间的关系都设计成功能块。

70年代中期的DCS只有模拟量控制。

DCS和PLC控制器的主要差别是在开关量和模拟量的运算上，即使后来两者相互有些渗透，但是仍然有区别。

80年代以后，PLC除逻辑运算外，也增加了一些控制回路算法，但要完成一些复杂运算还是比较困难，PLC用梯形图编程，模拟量的运算在编程时不太直观，编程比较麻烦。

但在解算逻辑方面，表现出快速的优点。

而DCS使用功能块封装模拟运算和逻辑运算，无论是逻辑运算还是复杂模拟运算的表达形式都非常清晰，但相对PLC来说逻辑运算的表达效率较低。

DCS和PLC在历史沿革上的差异是明显的，对它们后续的发展产生了重大影响。

然而，对后续发展影响最大的，并不是起源技术上的差别，而是其起源概念的差别。

DCS的核心概念是危险分散，数据集中的计算机控制系统，因此DCS 的发展过程，就是在不断的运用计算机技术、通讯技术和控制技术的最新成果，来构建一个完整的集散控制体系，DCS给用户提供的是一个完整的面向工业控制的安全可靠高效灵活的解决方案。

而PLC的核心概念是可编程序控制器，目的是用来取代继电器，执行逻辑、计时、计数等顺序控制功能，建立柔性程序控制装置。

所以，PLC不断发展的主线是在不断地提高各项能力指标，给用户提供一个完善的功能灵活的控制装置。

DCS是一个体系，PLC是一个装置，这是两者在概念上的根本区别。

这个区别的影响是深刻，它渗透到了技术经济的每一个方面。

欧陆新型DCS控制器

T2550自治控制系統（Autonomous Control System）英國歐陸公司新一代的集散控制系統（DCS）T2550是繼T100、T102、T103、T940後的新世代集散控制系統，新系統的名字叫“自治控制系統”（Autonomous Control System），這系统中包含了多個“自治控制器”（Autonomous Controller）互相之間連接到100Mbps 的高速工業以太網（如下圖二所示），其主要特點就是要屏棄傳統的擴展機座層的概念，在這先進的糸統中每一個機座都安裝上一個集合控制和通訊於一身的“自治控制器CPU”，它的主要功能是自行獨立處理從現塲檢測回來的信號、决策並執行控制策略任務，對本身機座上所有I/O 作出快速響應，此外，每台”自治控制器”都支持對等通訊功能，所以它們之間都能互相通訊和協調控制策略，由於這特出的功能，在一個大型的控制系統中，由這些“自治控制器”組成的系統就能發揮前所未見的優點。

假設在這大型的控制系統中有局部的設備或者控制器等發生故障時，整體系統都能繼續工作，通過自治控制系統適當的組態配置，把整個糸統分劃為多個自治控制區，在局部發生故障的時候，系統可立刻自動重組，實現容錯的控制，在云云的DCS系統中，更顯得出類拔粹。

圖一T2550的機座可帶最多128個I/O點，所以對一個1200點的控制系統而言，約需要12個機座，假使用户選用單CPU系統，我們要提供12個CPU，萬一其中一個機座的“自治控制器CPU”有故障，對整個系統而言，影響只限於局部性，但使用傳统的單CPU架構，加上多個擴展機座，萬一這台CPU發生故障，整個系統就要停頓下來，如使用“自治控制系統”，整個系統仍然能保持運行，當然，出現故障的部份，要維修好後才能繼續工作。

此外，我們的系統是支持100%熱備冗余功能，包括CPU、通訊模件、通訊電纜、供電源和I/O模件等，在原有的機座上CPU的右邊，插上另一塊新的CPU模件，便馬上把一個單CPU的機座變成一個熱備冗余的系統，是不需要對原有內部的控制策略作出任何修改，還有，以上的操作可在帶電的情況下在線進行，不需要停止正常運作中的生產過程，由于自治系統有高度的自治功能，我們亦可選擇性地把重要的機座配置成CPU熱備冗余，而其他的機座仍然是單CPU機座，如果要把全部機座都配置成熱備冗余機座是絕對可以的，這樣的配置遠比一般的離散系統的可靠性還要高出很多倍。

刀库管理相关

1. 概述加工中心通常带有刀库和附件库，选择一个高效可靠的刀具管理方案是加工中心设计与改造过程中必须着重考虑的。

原德国KOLB公司的CUBIMAT T/IT/VT/HT系列五面体龙门加工中心产品具有基本相同的机床结构，如图1是VT2500型带移动分度台的17轴机床示意图，它具有3个刀库U1/U2/U3、1个附件库U（自带3个附件头）、1个装卸刀库U4，配置2个机械手E1/E2及其水平移动轴V、垂直移动轴Q和旋转轴E3。

主加工区有常规的工作台X轴、滑座水平移动Y轴、滑枕垂直移动Z轴、横梁同步垂直移动W/W1轴和主轴C，另外配有移动式分度台A轴。

图1 CUBIMAT VT2500机床轴示意图SIEMENS 840D数控系统可选配刀具管理功能，它具有刀具装载、卸载、重新定位等功能，提供刀具管理数据修改功能FC块和后台数据块作为PLC接口，根据刀库结构形式来组态，灵活方便、功能强大，可适用于转塔式、链式、抽屉式以及一些特殊结构的刀库。

换刀、换附件通过NC编程与PLC编程相结合来实现，NC程序控制相应的轴移动，一定的步骤完成即通知PLC修改刀具管理数据，使其与实际状态始终保持一致。

由于刀库有关的10个数控轴通常分配在第2通道，NC编程时需注意两个通道之间的程序协调。

如果将这些轴改变为PLC轴，则可以通过PLC 程序来控制轴移动，为方便调试及点动操作，可设置单键切换回NC轴。

2. 机床参数MD18080——通用刀具管理功能定义，它有10位，分别激活相应的刀具管理功能，可根据机床需求设定。

MD20310——通道刀具管理功能定义，它有24位，分别对应不同的单项功能方式，可根据机床特点设定，但其低4位应与MD18080一致。

MD18082——刀具数量：150，最多600把MD18084——刀库数量：8，最多32个MD18086——刀位数量：120，最多600个MD18100——每个TOA域中刀沿数量：500，最大值＝MD18082×MD18106MD20110——复位功能模式，它有18位，决定NC复位后的各功能状态，如位6对应刀具偏置，结合MD20120和MD20130等参数决定刀具长度补偿在复位后是否保持有效；位14＝1对应基本零偏在复位后保持有效。

T2550_PAC介绍与选型

T 2550MODEL•Cost effective controllerProgrammable Automation Controller (PAC)Specification SheetP l a n t F l o o rVisualisationOperation ViewerStore & ForwardInformation Server Reporting ReportsOperation Server (System Platform)ValveEquipment ModulePhasesConfigurationAt the heart of the system is the LINtools configuration and engineering station. LINtools is a comprehensive set of configuration, test, documentation and commissioning tools for strategy elements distributed over the LIN control backbone. The LINtools suite includes graphical configuration of block structured continuous control, sequence control SFC’s, ladder and graphics for any LIN based product. VIEW and Online reconfiguration modes allow dynamic monitoring and editing of running databases and flow charts.LINtools follows the IEC 61131-3 standard for sequence configuration, while adopting a decoupling of continuous and sequential strategy appropriate to complex process control. LINtools is designed for simplicity and productivity. Online help, free-format text annotation and area editing are included to make LINtools easy to use and configuration easy to understand and reuse. LINtools runs on a standalone or networked PC.IEC 61131Languages appropriate for the I/O type and for the application °Function Block Diagram°Sequence Function Chart°Structured Text°Ladder Logic ControlOnline reconfigurationLarge and complex control systems are expected to serve many needs and work well for long periods without shutdown under ever varying workloads. Online reconfiguration provides a useful foundation for enhancement of a deployed control system and allows modification of the systems application software while it is running. It allows active strategy components to be modified, wrapped with additional functionality or replaced with a different implementation. The T2550 PAC has generic support for adding and hot swapping I/O. Online reconfiguration can use the same or new I/O interfaces and any internally available variables.You can tentatively add and delete function blocks and wires to create a new or improved control strategy for your application –while the process is running. You can then try and untry the strategy to ensure it is correct before final application. A secure file tracking system is provided for version control.Continuous controlContinuous strategies are configured graphically on screen using ‘block structured’ techniques implemented across the system. The control configurator supports a comprehensive library of functions together with powerful editing and compound definition facilities. Merging allows the re-use of similar sections of databases, avoiding duplication of effort. Free text can be placed on the screen or attached to function blocks for simple production of descriptive documentation.Context-sensitive help reduces the need of referring to manuals.SequenceSequences are configured graphically using Sequential Function Charts (SFCs) following the IEC 61131-3 standard. Steps initiate Actions which may be Structured Text statements (ST) or nested SFCs. Transitions determine when control passes from one step to the next. By accessing the continuous control strategy this configurator presents the available points through a menu system – eliminating the need to remember the names of points and reducing the likelihood of typing errors.The sequence configurator supports text annotation and context-sensitive help. A combination of mapping lists and generic Sequential Function Charts are available to easily duplicate identical SFC models on different units (tags).Action blockAction blocks in the continuous control strategy have their functionality defined in Ladder diagrams or Structured Text (ST) within a standard template. These are particularly useful for implementation of plant control modules.Auto I/O configurationThe instrument can automatically create its own LIN Database, including all necessary module and I/O Function Blocks, based on the I/O detected in the Base Unit. When the detection is complete, an operational database is created and runs automatically.Automatic database creation is available from within LINtools when connected to a network containing T2550 PACs. This function allows new I/O to be added to an existing configuration, on line.DocumentationLINtools provides an electronic documentation facility including the graphical representation of the control strategy and a listing of the block parameters and connections. This can be transferred across the network and output can be to a printer, Postscript or AutoCAD compatible format. Free-format user annotations can be added to complete your documentation requirements.Multi-setpoint programmerMany applications need to vary the process value over time. Temperature control is one such application in which it is very common to ‘ramp’ the process value (channel) from one level to another over a set time period using a setpoint program.The PAC provides support for multiple setpoint programs that can be run simultaneously. Each program is capable of profiling up to eight channels, with up to 32 segments per profiled channel. In addition to controlling the setpoint during each segment of the profile, the controllers can also be used to activate up to 16 digital events during a segment.The setpoint program feature enables an operator to select and run a pre-configured setpoint program. A preview facility allows the operator to view the selected program before running it. Once the program is running, the setpoint and achieved processvalues are plotted on the trend screen.Eurotherm Part No. HA029159 Issue 9 December 093PAC Specification SheetData archivingData archiving is used to copy selected parts of the history, i.e.,one or more history files (.uhh) to primary, secondary or tertiary FTP Servers..Historian store and forward‘Store and forward’ is a self healing 21 CFR Part 11 data archiving system which automatically stores data during a communication failure in the T2550 PAC and then forwards this data to theconfigured data historian server once communication is reinstated.The T2550 PAC provides dual redundant data acquisition using Secure.uhh files created at the local level, which results in a secure electronic recording system with total data integrity.Alarm managementAlarms are managed and collected within the T2550 PAC to provide features such as alarm status and priority,acknowledgement, date and time stamping at the source, as well s suppression and local message historian storage.Open communicationsThe PAC provides a special function block to define any simple serial communications protocol. This function block can be used to integrate many 3rd party devices which use ASCIIcommunications, such as bar code readers and particle counters.Direct control over transmit and receive also allows multi-node connections.HMI ReportsHMI Reports provides an intuitive reporting package to develop and print reports using the secure data from the T2550 PAC. The package includes a report studio for configuring report projects and a run-time execution module to generate and print reports in many different formats to printers and file servers, and via e-mail. HMIreports is also optionally available as a web portal.Setpoint program wizardFor ease of use, LINtools incorporates a wizard for creating a setpoint program. By following the on screen prompts and editing the parameters as required, a setpoint program can be simply and quickly created with all required blocks automatically created and added to the database.Setpoint program editorIn addition to the setpoint program wizard, programs can be created or edited off–line using the setpoint program editorsupplied with LINtools. As an ActiveX, this tool can be inserted in any of your visualization packages.Redundant recording and archivingPAC Programmable Automation Controllers have internal non-volatile flash memory for secure tamper resistant data storage,providing for redundant data logging. In addition all PACprocessors support Ethernet connectivity. As such, data stored within the internal flash memory can be configured to periodically archive to primary, secondary and tertiary FTP servers. Archiving files to FTP servers provides a secure, infinite archiving capacity.Data historianData historian is used to store PV’s, message and alarminformation in the internal flash memory in order to generate historical data in the form of a set of secure, tamper resistant history files.The following example provides estimated memory durationbased on an 8-way base logging 16 Parameters to a single group.FTP pushFor efficiency, historical data files are automatically deleted on a first in first out (FIFO) basis from the internal flash memory of the PAC (7Mb for history). In order to ensure longevity of data the PAC is able to push historical data files (.uhh) to primary,secondary or tertiary FTP servers at user defined intervals. Thus,depending on the archive strategy chosen, data is never lost. As an alternative, Eurotherm Review can be used to pull data directly from the T2550 PAC255BF base unitThe base unit is fitted with the T2550 PAC I/O controller modules plus additional I/O modules. These modules plug onto terminal units, which provide the wiring interface between the plant or machine and the I/O modules. Bases are available in 5 sizes to suit the number of modules required in a particular system.Communication between the I/O modules and the processor is effected by the use of a passive internal module I/O bus running the width of the base. Each module position is tracked separately for additional security during live replacement of I/O modules.The base consists of an aluminium extrusion, the internal I/O bus and mounting supports. It is designed to be DIN rail mounted or directly fixed to a bulkhead or mounting plate. Both base and modules can be installed horizontally or vertically.MechanicalI/O Module capacity0 46816Width (mm)36164214264467 Weight no modules (Kg)0.20.450.60.7 1.2all modules (Kg)0.5 1.3 1.7 2.1 3.7 Height:180mmDepth:102.9-132.9mm with retaining lever raised Mounting:DIN rail or Bulkhead, can be mountedhorizontally or verticallyDIN rail:Use symmetrical DIN rail to EN50022-35 x 7.5 or 35 x 15Casing:Without additional protection IP20 Ventilation space:25mm free space above and belowTermination unitsThe I/O modules are mounted on the base using terminalassemblies. Terminal assemblies provide the interface betweenthe input and output signals and the I/O modules. Terminalassemblies and I/O modules are keyed to inhibit insertion ofthe incorrect module to prevent damage to both equipmentand plant.Individual termination units provide for easy modulereplacement leaving the field wiring connected. Modules areinserted and removed from the termination unit using a unique,tool-less, locking lever system.Test disconnect unitsTerminal assemblies have an optional fuse or link (isolator or disconnect). This provides a series of connections between thecustomer terminals and the I/O module, permitting pluggablefuse or link units to be placed in series with the signal. Fuse andlink units are not interchangeable.T2550 PAC - General SpecificationsSupply voltage range:19.2 to 28.8V dcVA requirements: < 80W maximum for fully loaded rackFuse rating: 4A time lag (Not customer replaceable)IOC warm start time:12 hours without external batteriesIOC power consumption: 1.5W maximumSurge current:8A maximumModule pwr consumption:See individual module specification EnvironmentalOperating temperature:0 to 55°CStorage temperature:-25 to 85°CRelative humidity: 5 to 95% (non-condensing)RFIEMC emissions:BS EN61326-1:2006EMC immunity:BS EN61326-1:2006SafetyBS EN61010-1:2001Installation cat II, Pollution degree 2Safety earth and screen connections are madeto clearly marked earth terminals at thebottom of the baseVibrationEN60068-2 test FCVibration:IEC1131-2 section 2.1.30.075mm peak amplitude 10-57Hz;1g, 57-150HzShock:20g static shockDiagnostic LED’sDiagnostic LED’s indicate module diagnostic status.All modules: A green LED at the top indicates the moduleis powered and operating correctlyPAC analogue modules: Have red LEDs for each channel to indicatechannel failurePAC digital modules: Have Yellow LEDs for each channel to indicatethe channel state.Processor module:Primary processor and communications diagnostics are available from the LEDs on the front of the processor module.

Transfer from the primary to secondary processor is bumpless.The non-active processor can be replaced while the system is running and on synchronisation it loads its strategy from the active primary processor.Redundant:< 0.6s bumpless transfer for processor and I/O Changeover time: dependant on application size Synchronisation time: dependant on application sizeProcessor SwitchoverDuring a processor switch over all outputs remain at the last value. The new primary processor begins executing is application from precisely the same point as the original processor.Each processor has its own Ethernet IP address and each redundant pair uses two neighbouring node addresses on the ELIN network. This enables the system to communicate with the primary while still continuously testing communications to both processors. On processor switch over the ELIN node address is dynamically swapped to allow SCADA applications to display and log uninterrupted data. Changeover amongst LIN nodes is transparent.The following conditions can cause the processor to switch over:Hardware failure:Failure of primary controller internal health checks.Hardware removal: Removing the primary processor will cause the secondary to take immediate control.Removing the secondary will have no effect on control but will cause a system alarm on redundant configured systems.Internal communications:Primary and secondary controllers continually monitor the communications to the I/O on the local base. Should the primary controller not be able to communicate with the I/O and the secondary can still communicate with the I/O changeover will occur.If the secondary processor observes a fault in the primary communications or can see more I/O modules the secondary processor will request a changeover.External communications:Each processor in a redundant pair continuously monitors external controller communications. Should the primary controller not be able to communicate with other declared nodes on the LIN network and the secondary can still communicate with the declared nodes a change over will occur.If the secondary processor observes that it can see more declared nodes,the secondary processor will request a changeover.Manual request:A user can request a changeover if a secondary processor is running, synchronised and healthy.Removable flash memory card:The storage of the cold start application Power supply connectionThe duplex terminal unit supports dual power supply connection. In the event of a single power supply failure both processors are still supplied allowing redundant operation to continue uninterrupted.A super capacitor maintains memory for up to 12 hours in the event of complete power failure to facilitate hot start of the processors. An external battery can be fitted to extend this back up time on the redundant system.Super cap (Processor):Maintains memory/real time clock and enables hot start for up to 12 hours in absence of battery backup inputSimplex (O base):Battery support for data in SRAM and the Real-Time Clock for a minimum of 72 hourcontinuous (5 year intermittent use)Redundant:Additional terminals for an external battery connection to support SRAM and the Real-Time ClockInternal battery type:Lithium Manganese Dioxide PA250983External rechargeable battery:Use S9537 Battery charger:Use S9538Watchdog RelaysEach processor is fitted with a single watchdog relay.Watchdog relay:SPST, 1 per CPU, connectable in parallel or seriesContact rating (resistive):24V ac/dc at 0.5A Isolation:30V ac rms or 60V dcLive plug-inProcessors and I/O modules can be replaced while powered without any disturbance to the field wiring or other inputs and outputs – reducing downtime and minimising disturbance to other signal conditioning strategies.T2550 PAC – ORDER CODEControl specificationsContinuous Database resourcesMaximum database size . . . . . . . . . . . . . . . . . . .default max values 210k bytes Database resourcesNumber of database blocks . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .630Number of database templates . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .50Number of template libraries . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .32Number of external databases . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .32Number blocks in local Dbase cached elsewhere . . . . . . . . . . . . . . . . . .1260Number blocks in remote Dbases cached locally . . . . . . . . . . . . . . . . . . . .315Number of server tasks . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .6Number of field-to-field connections . . . . . . . . . . . . . . . . . . . . . . . . . . . . .1260Sequence Control ResourcesSequence memory Programme data . . . . . . . . . . . . . . . . . . . . . . . . .105k bytes SFC ResourcesNumber of root SFCs loadable . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .31Number of steps loadable . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .420Number of ‘wires’ permitted going into and out of step . . . . . . . . . . . . .1407Number of transitions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .630Number of ‘wires’ permitted going into transitions . . . . . . . . . . . . . . . . . .840Number of action associations . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .1680Number of actions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .840User TasksMultiple tasks are available to the user to tune the update rate of I/O response and the control function.User Tasks . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .4User task update ratesTask I – Synchronous to Fast I/O . . . . . . . . . . . . . . . . . . . . . . .10ms or N*10ms Only version 2 10ms I/O types can be assigned to this task (see table below) .Task 2– Auxiliary task to task1 . . . . . . . . . . . . . . . . . . . . . . . . .10ms or N*10ms Runs at task 1 rate or integer multiple of task 1 rateTask 3– Synchronous to Standard I/O . . . . . . . . . . . . . . . .110ms or N*110ms All analogue and digital I/O types can be assigned to this taskTask 4– Auxiliary task to task3 . . . . . . . . . . . . . . . . . . . . . . .110ms or N*110ms Runs at task 3 rate or integer multiple of task 3 rate Supported I/O Module TypesThe T2550 PAC shares I/O modules with the 2500 I/O.Notes†The T2550 PAC supports only Version 1 modules in simplex operation.*Version 2 Ana Out modules can run at the 10ms task on 4 or 6-way bases.

欧陆 T2550的使用经验

T2550的使用经验T2550是欧陆继T100、T102、T103、T940后的新一代产品，使用过程中，有些经验总结了一下，与大家分享。

1、校验仪的使用：校验仪是调试的有效工具，有些地方容易出错，用校验仪模拟４-20mA 信号时，如果屏幕显示mA,仪器向外提供电能，如果显示SIM ，仪器不向外供电。

2、温度压力补偿，FLOWCOMP 的使用。

下图是温度压力补偿模块的使用示例：Primary:原始流量PressIn：补偿压力TempIn：补偿温度Flow：补偿后的流量Pref: 设计压力Tref: 设计温度Pabs: 标准大气压Tabs：273.2PrimIndex:指数DCFindx: 指数DefaultP:默认补偿压力DefaultP:默认补偿温度Pfault: 是否用默认补偿压力计算Tfault: 是否用默认补偿温度计算ScalingK: 补偿系数计算的过程是根据一组数据（比如设计环境状态的数据）：补偿前后的流量，补偿压力、温度，确定ScalingK值。

要特别注意原始流量的量程要与计算过程相协调一致，注意标准立方与非标准立方的换算。

3、脉冲块PULSE的使用T2550的脉冲块PULSE有个特性，就是采用上升沿触发时，脉冲触发完成后输入信号In强制为0一次，而这时外部触发信号可能还是等于1，他会再次使In等于1，脉冲块再次触发，反复进行，达不到预想只触发一次的要求。

有个小技巧，采用下降沿触发就没有这个问题了。

4、A3模块的接线：P1，C1，P2,C2,P3,C3 模块向外供电I1，C1，I2,C2,I3,C3 模块不向外供电5、MODBUS（RS-485）通讯，T2550做从站，PKS-C300系统做主站6、MODBUS（RS-485）通讯，T2550做主站，Ｓ７-300做从站。

硬件接线插脚定义如下图示，特别注意橙色/白色接A，橙色接B，某些资料是错误的说明：从站偏移地址为2 的hold数据，主站用偏移地址40002，功能码3，6读写似乎不能成功，主站用偏移地址2，功能码3，6读写，能读不能写；从站偏移地址为2 的read数据，主站用偏移地址40002，功能码4读似乎不能成功，主站用偏移地址2，功能码4读，成功。

2550注意事项

1、T2550平台须知：1.1、关于热启动T2550在断电重启后首先进入热启动模式，若不成功则进入冷启动模式（须将SW2:2及SW2:3置为ON）。

在未连接扩展电池（3V）的情况下，控制器断电，大约20秒之内重新上电可进入热启动方式，MONITOR所修改的参数可以保存。

超过该时间，则控制器冷启动，加载CF卡中保存的组态。

1.2、关于在线保存组态在线保存之后，可从欧陆浏览器中发现，其修改时间变为2000年某月某日，有误。

在线保存的组态中，若有PID模块，其输出OP值不能记录，显示为0。

可以在PID出口增加MA TH模块（ADD，SUB等），用以记录OP值。

1.3、关于看门狗看门狗为常开节点，在报警及断电时打开，正常运行时闭合。

触发看门狗的条件：（1）上电自检失败，10S后看门狗动作（节点打开）（2）上电自检成功，进入启动初始化状态，此时看门狗动作，直至初始化完成。

将SW2:1设置为ON，则看门狗动作时，控制器自动重启，指示灯同时点亮（看门狗动作时，包括故障灯在内所有指示灯均熄灭）。

机柜设计时把输出串连连接送入报警光子牌，报警时显示控制器故障；若没有报警光子牌则送入DI通道，MMI中完成报警。

注意：控制器同步退出在MMI中应显示同步退出，不应显示控制器故障，以免运行人员误解。

1.4、关于TASK设置所有IO模块必须设为TASK3时间应设为N*110ms，其中N=1,2,3……。

1.5、关于T2550容量控制器容量限制如上图左，SFC容量限制如上图右。

♦DBSIZE限制为85，实际应为83左右。

连线数限制为510，实际使用中可以略超出一些。

组态过大有可能出现NOACTION、连线失效等情况。

连线失效一般出现在远传至本地的模块上（该连线的扫描等级最低）。

♦SFC中，STEP限制为212，MAXSFCsz限制为59，这两项容易超限，导致顺控无法正常运行。

♦应用中FEA TT数量超限是导致控制器不能正常运行的重要原因。

T2550基本功能介绍

T2550基本功能一、硬件方面：（1）、T2550控制器兼容的IO模件清单：（2）、T2550特性如下：1）：T2550 的通信是通过以太网LIN通信协议，我们常说的ELIN网络；2）：控制器相互冗余，供电冗余；3）：T2550主从控制器冗余，在正常冗余工作模式下，主从控制器之间的高速数据连接使得从处理器真正的跟踪控制数据库，实现主从控制器无扰动切换；4）：T2550可带电插拔；（一般拔出的控制器要10S后再上电，另拔插要注意主从关系，一般先把从、故障控制器）（3）、T2550的硬件设置：T2550的前面板布局：（见电子书的2.3.1）（4）、T2550后面板布局：SW1：S1一般设置为ON，S2~S7，根据分配地址做相应的跳线。

请将switch2的2、3 两个开关置为1，将CPU置为热启动/冷启动方式，不要使用自动生成数据库的方式。

T2550预留了通讯接口，以代下一步开发。

（5）、T2550的网络结构：每一个T2550模块都有一个10/100Mbase T端口通过标准的RJ45接口进行以太网通信。

直通连接双绞线：在网络连接过程中要注意：冗余的一对T2550控制器要分别连接到2只交换机上。

注意：1）禁止一对冗余的控制器连接到一只交换机上;2) 禁止在处于运行中的控制器随意调换；3）禁止在运行中的交换机上测试网线；4）禁止把已配置好的控制器在网络上随意调换；5）禁止网络线、控制器受力、拉扯；6）禁止把T2550控制器中的CF卡随意调换二、软件方面1、关于T2550中TASK设置4个TASK设置，一般设置原则是N*110 ms（N=1,2,3,4….）。

正常情况下，将TASK任务设置为TASK1=110ms、TASK2=220ms、TASK3=330ms、TASK4=440ms，一般组态全部设置为TASK3=330 ms。

对于需要快速扫描的模块，如ETS保护功能模块，在相应的IO设置为TASK1，逻辑模块设置TASK2时，注意相关逻辑部分要求为同等任务。
