There are no special hardware requirements. Therefore, the minimumrequirements specific to the operating system apply. You can find theserequirements on the appropriate Microsoft websites.3 Software Requirements3.1 Operating EnvironmentOperating SystemsS7-PDIAG V5. 7 can be used with the following operating systems:•MS Windows 10 Pro and Enterprise (64-bit)•MS Windows Server 2016 (64-bit) (Standard Edition as work station computer)•MS Windows Server 2019 (64-bit) (Standard Edition as work station computer)S7-PDIAG has not been tested on any other operating systems; use at your ownrisk.Compatibility toolWith the compatibility tool, you can put together a compatible selection of softwareproducts or check existing configurations for compatibility. You can find thecompatibility tool at:https:///cs/ww/en/view/64847781STEP 7S7-PDIAG V5.7 runs on the STEP 7 basic package V5.7 (or higher).The hardware and software requirement for installing STEP 7 must be met (see theSTEP 7 readme file).Internet-ExplorerAll operating systems must be use MS Internet Explorer 6.0 (or higher).User RightsTo be able to work with S7-PDIAG in MS Windows 10/Server 2016/2019 you musthave logged on at least as the primary user. You must have administrator's rightsfor installing the S7-PDIAG software and also for setting up modules using the"Setting the PG/PC Interface" application.If S7-PDIAG is installed on an NTFS drive, the administrator has to grant all theprimary users working with S7-PDIAG full access to the S7-PDIAG installationdirectory. Use the "Security" tab for this. You can get to it via the Sharing andSecurity... menu command in the Windows Explorer context menu. If this tab isnot available under Windows, then you have to clear the "Simple File Sharing(recommended)" check box in the Windows Explorer via the Tools > Folderoptions... in the "View".If projects are saved on NTFS drives, all primary users have to be granted fullaccess.File systemsS7-PDIAG achieves a slightly lower performance when operating on a MSWindows NT file system (NTFS) as opposed to a FAT file system.3.2 Memory RequirementsS7-PDIAG Memory RequirementsDepending on the number of languages installed, S7-PDIAG V5.7 requiresapprox.24 MB and 26 MB of memory on your hard disk. The exact value alsodepends on your operating system and on the file system used on yourprogramming device/personal computer.3.3 Online DocumentationThe S7-PDIAG V5.7 online help is split into two sections.You can find notes on the current context in the same way as with the standardWindows help.The general section of the online help is based on the HTML format. You can findmore information on the structure of the documentation in Chapter 7 (in Notes onUsage) in the second half of this README file (S7-PDIAG-readme.rtf).3.4 Upgrading an earlier version of S7-PDIAG3.4.1 S7-PDIAG V5.7 UpgradeTo install the upgrade package, you require a valid license for S7-PDIAG V5.3 orV5.6.4 Installation4.1 Installing S7-PDIAG V5.7You can install S7-PDIAG V5.7 over a previously installed version of S7-PDIAGV5.6. You do not have to uninstall these versions of S7-PDIAG first.In order to obtain the optimum display of the information during the Setup, youshould set the color scheme in the control panel of your programmingdevice/personal computer to at least 65536 colors.Insert the S7-PDIAG-DVD in the drive. The setup program will guide you throughthe installation of S7-PDIAG. The setup program starts automatically after the S7-PDIAG-DVD has been inserted in the drive. If you have disabled this function onyour computer, start the setup program with MS Windows Explorer by double-clicking the SETUP.EXE program in the root directory.In the component selection box, select the components you want to install.These components will then be installed and entries will be made in MicrosoftWindows files.S7-PDIAG is automatically installed on the drive where STEP 7 is located.NoteS7-PDIAG registers itself in MS Windows system files. You cannot move orrename S7-PDIAG files or folders using Microsoft Windows utilities such as theExplorer or modify S7-PDIAG data in the Microsoft Windows registry. The programmay no longer run properly after such modifications.4.2 S7-PDIAG V5.7 License KeyBefore you can start working with S7-PDIAG, you have to transfer the license keyfrom the license key USB stick to the computer. There are two ways of doing this:•While you are installing S7-PDIAG, the Setup program displays a message if there is no suitable license key installed on your computer. You can thendecide whether you want the license key to be installed by the “Setup” programor whether you want to install the license key manually at a later time using the“Automation License Manager” program.•If the license key cannot be installed during setup, continue the Setup program without installing the license key. Install the license key after the S7-PDIAGinstallation via the Start menu (for example, Windows 7) Start > All Programs >Siemens Automation > Automation License Manager.The Automation License Manager has to be installed for the S7-PDIAG operation.NoteAs of S7-PDIAG V5.3 the license key can be installed on all local drives.The Automation License Manager prevents the authorizations and license keysfrom being installed on invalid drives or media such as RAM drives, diskettes orcompressed drives (i.e. DBLSPACE). If the drive in a device is reported as being a"removable medium" and not, as usual, as a "hard drive", it will be treated as aDVD, which means that no license keys may be installed on it.In the case of compressed drives, you can install the authorization on theassociated host drive.You absolutely have to follow the notes in the Automation License Manageralmreadme.rtf file on the S7-PDIAG Installation DVD.Hidden files are stored in the folder "<Drive, on which the authorization/license keyis installed>:\AX NF ZZ". These files and the folder must not be deleted, moved, orcopied. They contain data required for the authorization of your software.If you do not adhere to these guidelines, the authorization may be irretrievably lost.Notes on error-free use of the license keys•The License Key USB stick must not be read-only. Because the License Key USB stick is to be used without write protection, there is a danger that a viruscould be transferred from the hard disk to the USB stick. You should thereforerun a virus check on your PC or programming device every time you install orremove a license key.•If you use an optimizing program which enables you to move fixed blocks of memory, only use this option if you had previously moved the license key fromthe hard disk back to the License Key USB stick.•When you install a license key, a specially marked cluster appears on the target drive. Some test programs mark this cluster as "defective." Do not attempt torestore the defective cluster.•Do not forget to transfer the license key to the License Key USB stick before formatting, compressing, or restoring your hard disk or before installing a newoperating system.•If a backup copy of your hard disk contains copies of license keys, there is a danger that these copies may overwrite the valid installed license keys whenyou restore your backup data to the hard disk, thereby destroying the validlicense keys. To prevent a valid license key from being overwritten by a backupcopy, you must remove all license keys before you make a backup copy orexclude the license keys from the backup.Using the trial licenseIf there is no valid license key installed for S7-PDIAG V5.7, the default triallicensesupplied with S7-PDIAG is installed and used. This license key can be usedonly 21 days. With the first S7-PDIAG start without a valid license key, the triallicense is activated after confirmation.4.3 Uninstalling S7-PDIAG V5.7Software products must be removed according to Microsoft Windows conventions.Use the Microsoft Windows application "Add/Remove Programs" (in the taskbar inStart > Settings > Control Panel > Programs and Features) to remove yoursoftware package (for example, "SIMATIC S7-PDIAG V5.7").Alternatively, you can also uninstall using the setup program.These notes should be considered more up-to-date than the information inmanuals and online helps.5 New Features and Changes in the NewVersionWhat's New in Comparison to Version 5.6?Please read the "What's New" RTF file on S7-PDIAG found on the S7-PDIAGDVD.6 Notes on Configuring and Operating theSoftwareNotes on Usage (Release Notes)These notes should be considered more up-to-date than the information inmanuals and online helps.6.1 General NotesThe general notes on the STEP 7 V5.7 basic package and later are fully valid inconnection with S7-PDIAG.6.2 S7-PDIAG V5.7 Technical Specifications6.2.1 Released CPU ModulesYou require a S7-300/400/WinAC CPU with the message functions ALARM_S/ALARM_SQ (SFC 17/18) and ALARM_D/ALARM_DQ (SFC 107/108) to be able towork with S7-PDIAG.Please use the documentation to check the CPU you are using for the availabilityand specifications of ALARM_S/SQ and ALARM_D/DQ. S7-PDIAG requiresALARM_S or ALARM_SQ at least.6.2.2 Memory Requirement EstimationThe specified values are approximate values, they are dependent on thecomplexity of the networks to be monitored and on the monitoring logic.NoteYou cannot configure and use more than 10 groups because of the maximumblock size of 8 Kbytes with CPU 314/315.6.2.3 Approximate Values of the Cycle LoadYou will achieve a cycle load below 10ms with the number of monitoring givenbelow:•CPU 314/315: level monitoring with timer + 100 without timer•CPU 413/414: level monitoring with timer + 400 without timerIf you have configured groups, the cycle time per group will increase by•CPU 314/315: 1 ms•CPU 413/414: 0.6ms6.2.4 Number of Communication Nodes with Process DiagnosticsDepending on the CPU type, there are upper limits with the S7-CPUs as regardsthe nodes which can be logged on simultaneously for the message functions usedby S7-PDIAG.The possible number of communication nodes (OP / WinCC / PG) of the messagefunction ALARM_S / ALARM_SQ used by S7-PDIAG is determined by the CPUtype.Please check the number of communication nodes for S7 message functions inyour corresponding CPU documentation.6.3 Libraries and Sample ProjectsA library and a sample project are supplied with S7-PDIAG V5.7.These sample projects can be deleted in the SIMATIC Manager. To reinstall them,you have to run the S7-PDIAG V5.7 setup program again.NoteThe sample project and library shipped with S7-PDIAG V5.7 are always copiedwhen you install S7-PDIAG. If you have edited the standard sample projects, theywill be overwritten with the original examples if you reinstall S7-PDIAG V5.7.You should therefore make a copy of the standard examples before you makechanges to them and then make changes to the copy.6.4 Notes on Working with S7-PDIAG6.4.1 Address PriorityIf changes in symbols result in changes to process diagnosis data for which the setaddress priority is to be followed, then these changes will be made when a projectis opened with the application S7-PDIAG or when a block with diagnostic capabilityis opened in the LAD/FBD/STL editor.These changes are not made in the symbol editor.6.4.2 Virtual Unit OverviewIf the view "Virtual unit overview" is disabled, you will only be able to moveinstances to other groups via the Group.6.4.3 Update Message Texts Using Symbol TableIn S7-PDIAG a symbol name or comment is configured as a message. If themessage text is changed manually in the symbol table or automatically using amultilingual tool, the message text will have to be compared with the symbol table.To do this, the check box for "Update Message Texts Using Symbol Table" (menucommand Options > Customize, Compile tab) in S7-PDIAG has to be activated.The update will then be performed during the generation of the process diagnosticseither via Process Diagnostics> Compile or Process Diagnostics > Compilecompletely.The activation of the check box in the customize dialog and generation is onlypossible if S7-PDIAG is installed.7 Notes on DocumentationComprehensive documentation on S7-PDIAG is available to you in the online helpfor S7-PDIAG.

S7.PDIAG过程诊断功能介绍
图1 由符号表产生的消息图2 块调用产生的消息S7-PDIAG软件通过内部调用系统函数SFC17、18、107、108完成消息的传送（SFC107、108替代SFC17、18,与之相比带有通信资源管理功能）。
2．S7-PDIAG软件诊断功能的种类S7-PDIAG包含三种诊断功能，分别是地址监控（Address monitoring）、全局监控（global monitoring或General monitoring）和运动监控（Motion monitoring），下面分别介绍这三种诊断功能。
2.1 地址监控地址监控功能监控一个位信号的状态变化，可以设定一个沿信号和电平信号，设置界面如图3所示：图3 地址监控功能设置界面在“Initial Diagnostic Address”设置监控的地址，如M1.1,然后选择监控的信号，如沿信号和电平信号，如果激活“Delay”功能，则需要设定相应的延迟时间，表示如果监控信号变化，将延迟设定的时间后触发，S7-PDIAG在程序内部调用SFC64，时间格式为IEC标准，例如T#1H19M12S100MS 表示的时间值为1小时19分12秒100毫秒，配置的延时定时器的个数没有限制。
在“Meassage”栏中设定信号触发的消息和优先级，配置完成后点击“OK”键确认。
2.2 全局监控全局地址监控功能监控一个表达式，如果表达式结果为1则触发消息，设置界面如图4所示：图4 全局监控功能设置界面在“Meassage”栏中设定信号触发的消息和优先级，配置完成后点击“OK”键确认。
2.3 运动监控运动监控对用户编写的定位过程进行监控，运动监控有下列几种监控方式：1）执行监控（Action Monitoring）当启动命令执行后，在设定的时间内没有到达定位的位置（限位信号），触发消息的生成。
执行监控的设置界面如图5所示：图5 运动监控－执行监控功能设置界面执行监控界面中使用S7-DIAG语言预先设定触发条件并不可以修改，如图5中，如果M1.2为1（执行），20秒后M1.1（限位开关）没有到达，触发报警消息。
