浅谈HONEYWELL PKS控制系统故障及处理方案

浅谈HONEYWELL PKS 控制系统故障及处理方案刘成徐继友张祥(兖州煤业榆林能化有限公司，陕西榆林 719000)摘要：本文以兖州煤业榆林能化有限公司甲醇厂60万吨煤制甲醇项目主工艺流程空分、气化合成工艺所用DCS 系统为切入点，对系统运行维护过程中出现的典型故障研究分析，为发生类似故障造成停车风险提供参考，有效避免类似事故再次发生。

关键词：DCS 系统、故障、维护、处理方案1 引言兖州煤业榆林能化有限公司甲醇厂年产60万吨甲醇煤化工项目，该项目采用德士古气化工艺，主要有空分、气化、合成等主界区。

主界区采用霍尼韦尔DCS 控制系统，本文主要介绍在运行过程中将出现的故障及处理方法。

2 故障现象描述某生产工作日6：40，工艺人员反映气化界区操作站反复出现PKS 系统报警。

从DCS 软件在线查看卡件状态正常，服务器也无异常现象，到机柜间检查PKS 系统控制器等卡件均为正常状态。

07:15，又接到合成车间工艺人员电话反映LI20001、LI20006等数据静止无变化并且画面反应较慢，这些数据皆为FSC 系统通讯至DCS 系统的数据。

现场工程师在线登陆FSC 系统检查，程序正常；机柜间查看FSC 机柜卡件发现通讯卡(型号10018/E/12)通讯状态灯为绿色正常；数据传输灯闪烁异常(闪烁慢，有时不闪烁)初步判断数据通讯不正常。

07：20分左右，经过检查发现FSC 和DCS 的2个冗余通讯的错误率都达到50%以上，立即重启FSC 的一个通讯卡，等指示灯正常后再重启另一个，然后检查发现错误率依然从0%一直增加。

期间几次出现服务器及操作站上位画面全部无数据现象,阀门、泵等均无法操作，在console station 上也无法进行操作。

DCS 下位程序CM 等有时变为红色。

期间由于FSC 通讯到DCS 的一个通讯点数据不正常(FSC 为“1”信号，DCS 通讯变为“0”信号)导致阀门关闭从而使B 号气化炉跳车(A 号气化炉和B 号气化炉同样的组态模式但没有出现这样的情况，也未跳车)。

Called a clone backup, the file created by a USB backup contains a complete image of the platform and station, including system modules and the QNX OS.NOTE: Starting in NX 4.2, the HAWK 8000 can be converted (downgraded) to run AX 3.8.111.6.5 – with somefeature limitations. For example, for any HAWK 8000 running AX the USB Backup/Restore functionality isnot supported. When running AX, the USB port on the device is not monitored. Other unsupported features are IEEE 802.1X wired authentication and WiFi functionality.The BackupService, which comes standard with COACH NX, backs up station files to a local Supervisor or browser PC. A backup made by the BackupService includes only pointers to required core software modules. To restore from a backup made using COACH NX, not only do you need COACH NX, but also its software database with matching versions of all required core .dist files, OS .dist files, and software modules. Afterwards, use the Distribution File Installer to restore the backup.The HAWK 8000 provides the ability to:• Initiate a backup manually by inserting a USB flash drive into the USB port and pressing the backup and restorebutton on the unit itself.NOTE:USB backup supports only FAT32 and FAT32X file systems. NTFS is not supported.Risk of equipment damage!► Only flash drives (USB sticks ≤128GB) are recommended for backup/restore operations. USB bus-powered ex-ternal hard drives often have higher power requirements and so may not function as expected, possibly resulting in permanent damage to the drive or to the HAWK 8000. Plugging in an external hard drive may cause the controller to become unresponsive, requiring a reboot.• Restore a USB backup image using a USB flash drive, USB-to-Micro USB cable connection and a terminalemulator program.• Recover the factory default image. This feature does not require a USB flash drive, special cable or terminalemulator. The system pulls the factory image from non-volatile, read-only memory.Creating a USB BackupYou may create a clone backup while a station is running or stopped. When the controller is powered on, the software continuously monitors the USB port. Putting a USB flash drive in the port triggers backup/restore mode.Prerequisites:• USB backups are enabled on the controller: Platform Administration →Advanced Options →USB Backup Enabledproperty is selectedNOTE: USB backup supports only FAT32 and FAT32X file systems. NTFS is not supported.• You need a USB flash drive with enough memory to contain the complete platform and station image along withthe operating system and all software modules.Step 1:Confirm that the controller's power is ON. Step 2: Insert a USB flash drive into the USB port.The backup and restore LED turns ON.HAWK 8000 CONTROLLER – BACKUP & RESTORE GUIDEEN2Z-1027GE51 R05174Fig. 1.

While backing up, the LED flashes slowly (one second ON, one secondOFF). When the backup completes, the system prepares the USB flash drive to be removed safely.NOTE: If the backup is unable to complete successfully, the LED flashes rapidly (200 ms ON, 200 ms OFF, 200ms ON, 3 seconds OFF), indicating an error. In this case, simply unplug the USB thumb drive, wait for theLED to turn OFF, then insert the thumb drive and try the backup procedure again.If problems persist, possible causes could be:• Insufficient disk space on the thumb drive• Write protect enabled on the thumb driverStep 4: When the backup and restore LED turns OFF, remove the USB flash drive and store it in a safeplace.The backup image includes the contents of the boot partition, /home/niagara, /opt/niagara, etc. The nameof the resulting image file follows this convention: hostid (unique host ID of the HAWK 8000), underscore(_) timestamp. For example:• Qnx-TITAN-D01C-CA36–CB10–4E3B_20170912230355• Qnx-TITAN-D01C-CA36–CB10–4E3B_20171015212346Restoring from a USB BackupRestoring from a USB backup returns the controller to the state it was in when the system made the backup.You may restore to a controller other than the one on which the backup was made, provided that the target controller is the same model. The restore procedure does not require access to COACH NX.HAWK 8000 CONTROLLER – BACKUP & RESTORE GUIDE5 EN2Z-1027GE51 R0517Prerequisites:• The USB flash drive on which the backup is stored.Risk of equipment damage!► Only flash drives (USB sticks ≤128GB) are recommended for backup/restore operations. USB bus-powered ex-ternal hard drives often have higher power requirements and so may not function as expected, possibly resulting in permanent damage to the drive or to the HAWK 8000. Plugging in an external hard drive may cause the controller to become unresponsive, requiring a reboot.• A USB-to-Micro USB cable (same cable as that used to connect a smart phone to a computer). The Debug port on a controller is a standard Micro-A type USB port for debugging serial communications.• A terminal emulator (system shell program), such as PuTTY. You use this program to access the controller's system shell menu, which lists the restore options.• The system passphrase of the system to which you are restoring the backup.• The system passphrase used to create the backup. If you are restoring the image to a different controller (another of the same model), or if the system passphrase for the controller on which the backup was made changed since you made the backup, the passphrase required to decode the backup will be different from the current system passphrase.NOTE:For any HAWK 8000 converted to run AX, USB Backup/Restore functionality is not supported. Also, the USB port on the device is not monitored for insertion/removal of devices. Step 1: Set up the terminal emulator program running on your PC with the following settings:• baud rate: 115200• data bits: 8• parity: N• stop bits: 1For details on using a serial connection to this port, see HAWK 8000 – Installation & CommissioningInstructions (EN1Z-1027GE51).Step 2:Ensure that the controller's power is OFF. Step 3:Connect the USB-to-Micro USB cable from the computer to the controller's micro USB port (Debug port). Step 4:Insert the USB flash drive that contains the backup into the USB port. Step 5: Press and hold down the backup and restore button throughout the boot-up process (approx. 5seconds) until the button press is detected and this confirmation banner displays:******************************************************* Backup/Restore button press detected. Release button now to proceed.*******************************************************Step 6: Release the backup and restore button once the banner displays.On detecting the button release, the system begins a 10-second countdown, which displays as shownhere:Press any key to restore from USB backup. If no key pressed, factory recovery will begin in 10 seconds Recovery begins in 9 seconds Recovery begins in 8 secondsRecovery begins in....Step 7:Press any key during the 10-second countdown to restore from a USB backup (and to prevent the system from entering factory recovery mode).HAWK 8000 CONTROLLER – BACKUP & RESTORE GUIDEEN2Z-1027GE51 R0517 6Risk of information loss!► If no key press is detected during this 10-second countdown, then the factory recovery process begins at the moment the countdown finishes.The system enters the USB restore mode and the following banner displays:******************************************************* Restore from a USB Backup*******************************************************Existing Niagara and platform installation will be completely removed! This includes licenses TCP/IP and WiFi configuration platform credentialsIf restoring a backup from another unit, you will need to install a new license.TCP/IP configuration and platform credentials will be set to values in the backup.Niagara daemon and station will be killed if they are currentlyrunningEnter the system passphrase for this system to proceed, or return toexit and rebootStep 8: At the passphrase prompt, enter the current system passphrase for the controller.One of the following happens:• If the entered passphrase does not match the system passphrase for this controller, after prompting a second time and no match, the backup and restore LED flashes rapidly (200 msec ON, 200 msec OFF)and it prompts you to reset the system.• If the entered passphrase and the passphrase stored on the controller match, the system waits while the USB drive mounts, this can take a few minutes. The following message appears:Waiting for USB drive to mount. Press any key to quit and reboot.Once USB drive is detected, the following message and options display:USB drive detectedThis platform is Qnx-TITAN-61BA-B6DB-88FE-4A31Please make your selection below1) Abort Recovery/Restore mode 2) Show backups for other host IDs3) Qnx-TITAN-61BA-B6DB-88FE-4A31_20151119154109Step 9: Type the number for a listed backup file name (for example: 3) or other option and press Enter.NOTE: The backup file name is the name of the backup file stored on the USB flash drive:(hostid (unique host ID of the controller), underscore (_) timestamp) The system prompts you to enter the passphrase for the backup file.Step 10: At the prompt asking if the backup file's passphrase is the same as the system passphrase for thecontroller, type Y (yes) or N (no).• If Yes, then the system passphrase entered in the earlier step is used to decode the backup.• If No, you must enter the passphrase for the backup file to decode the backup.Step 11: If you entered N in the previous step, at the prompt enter the passphrase for the backup file, andconfirm it.HAWK 8000 CONTROLLER – BACKUP & RESTORE GUIDE7 EN2Z-1027GE51 R0517The restore begins.Risk of equipment damage!► Once a restore begins, do not interrupt the process by removing the USB flash drive, disconnecting the power, or pressing the backup and restore button again. If you do not allow the restore to complete, thecontroller could be left in a non-functional state.When the restore successfully completes, the backup and restore LED turns OFF and the system displays a message indicating that the restore is complete and that the controller requires a reset.Step 12: Turn the controller's power OFF and back ON again.Restoring Factory DefaultsThe process of restoring factory defaults returns the HAWK 8000 to the state it was in when it shipped from the factory. This procedure describes the steps to restore factory defaults when using a terminal emulator program to access the controller's system shell menu.Prerequisites:• A USB-to-Micro USB cable (same cable as that used to connect a smart phone to a computer) connecting the HAWK 8000 to your PC. The Debug port on a HAWK 8000 is a standard Micro-A type USB port for debugging serial communications.• A terminal emulator (system shell program), such as PuTTY, installed on your PC.Risk of equipment damage!► Recovering factory defaults removes all platform and station data in the HAWK 8000. Be sure to backup data prior to performing this procedure.The following are a few scenarios for which you might choose to restore factory defaults:• While commissioning a brand new HAWK 8000, you make an error entering the default platform daemoncredentials or passphrase. The result is that you cannot commission the HAWK 8000. In this scenario, your only recovery option is to restore the factory defaults.• When decommissioning the HAWK 8000, a best practice to follow is recovering the factory defaults in order to wipe all of the platform and station data in the HAWK 8000.Fig. 2 indicates the position of USB ports and pushbuttons behind the access door.HAWK 8000 CONTROLLER – BACKUP & RESTORE GUIDEEN2Z-1027GE51 R05178Fig. 2.

And although holding down the Backup button during power up/boot up still functions to initiate a factory recovery image, it restores the controller to its factory ship state which is NX 4.2.36.34.2.14 orlater. You must repeat the conversion procedure to get it to AX 3.8.111.6.5.• The DEBUG port is a standard Micro-A type USB port for serial debug communications to the HAWK 8000.For more details, see section "About HAWK 8000 System Shell Mode" in HAWK 8000 Controller – Install & Start-Up Guide (EN1Z-1027GE51).NOTE: Login requires administrator level platform credentials.• The SHT/DWN pushbutton initiates a "controlled shutdown" of the HAWK 8000, ensuring that all station data ispreserved.Step 1:Ensure that the controller's power is OFF. Step 2: Press and hold down the backup and restore button as you power up the HAWK 8000, andcontinue holding down the button throughout the boot-up process until the button press isdetected and the following confirmation banner displays:******************************************************* Backup/Restore button press detected. Release button now to proceed.*******************************************************NOTE: During this step of the procedure, the Backup LED flashes at medium speed (100 msec ON,100 msec OFF). Also, be aware that holding the button down too long results in the followingmessage (which does not indicate a hardware fault). If this message appears, it is best to startthe procedure over, beginning with step 1:"WARNING - CHECK BACKUP BUTTON - POSSIBLE SHORT!"Step 3: Release the backup and restore button once the banner displays.HAWK 8000 CONTROLLER – BACKUP & RESTORE GUIDE9 EN2Z-1027GE51 R0517On detecting the button release, the system begins a 10-second countdown, which displays as shownhere:Press any key to restore from USB backup. If no key pressed, factory recovery will begin in 10 seconds Recovery begins in 9 seconds Recovery begins in 8 secondsRecovery begins in....NOTE: Pressing any key during this 10-second countdown prevents the system from entering factoryrecovery mode. Instead, the system switches modes to restore from a USB backup.When no key press is detected during the 10-second countdown, the factory recovery process begins at the moment the countdown finishes. Upon entering recovery mode, the boot process overwrites the HAWK 8000 with a default factory image. During this process, the Backup LED blinks at slow speed (one second ON, then one second OFF).Risk of equipment damage!► Once in recovery mode (Backup LED is flashing in slow blink), do not interrupt this process. Allow the recovery to complete or the HAWK 8000 could be left in an inoperable state.Step 4: When the Backup LED stops flashing, turn the controller's power OFF and back ON again toreboot.NOTE: After restoring factory defaults, the initial HAWK 8000 reboot process takes longer than usual. On completion, the HAWK 8000 is restored to a factory default state.Shutting Down the ControllerThe shutdown procedure allows you to safely shutdown the HAWK 8000.Step 1: Press and hold the Shutdown button until the Backup LED begins to flash.NOTE:In QNX 4.3, the heartbeat LED also turns OFF, and all Ethernet, USB, and console connectivity is lost. Step 2:Once the Backup LED begins to flash, release the Shutdown button. Step 3:Once the Backup LED turns ON (solid) and begins to flash, wait until the Backup LED turns OFF. Step 4: Remove power to the HAWK 8000.NOTE: If you have a terminal connected to the HAWK 8000, the following message displays when theshutdown process is complete and it is safe to remove power:iomonitor: shutdown complete, safe to remove powerHAWK 8000 CONTROLLER – BACKUP & RESTORE GUIDEEN2Z-1027GE51 R0517 10 REFERENCE INFORMATIONTopics covered in this chapter♦ Platform and station backup options♦ Restore options♦ Shutdown operationsThe following sections provide additional backup, restore, and shutdown reference information.Platform and Station Backup OptionsSeveral options are available for backing up platform and station data.NOTE:USB backup supports only FAT32 and FAT32X file systems. NTFS is not supported.Risk of equipment damage!► Only flash drives (USB sticks ≤128GB) are recommended for backup/restore operations. USB bus powered ex-ternal hard drives often have higher power requirements and so may not function as expected, possibly resulting in permanent damage to the drive or to the HAWK 8000. Plugging in an external hard drive may cause the controller to become unresponsive, requiring a reboot.In Niagara, the term backup describes different operations.

When the controller detects that the Shutdown button is being pressed, it enters the shutdown mode. This is indicated by the Backup LED flashing the alert mode pattern (100 msec ON, 100 msec OFF).To verify that the Shutdown button is functioning and not in a failed state, the controller must detect the buttonrelease before proceeding. Once the button is released, the controller puts the software in a safe state. During this process, the Backup LED toggles with the work pattern (1 s ON, 1 s OFF). Once the software has successfullycompleted its process, it notifies the controller that it is safe to shutdown. The controller turns OFF the Backup LED, indicating it is safe to remove power.In the event that the software is unable to put the system into a safe state, the software notifies the controller that it could not complete the request. The controller then indicates this by toggling the Backup LED with the error pattern (200 msec ON, 200 msec OFF, 200 msec ON, 3 s OFF).。

霍尼韦尔DCS的变迁看过程自动控制系统的发展

摘要：本文主要通过回顾霍尼韦尔公司DCS系统的30多年发展历程，重点介绍霍尼韦尔新一代Experion PKS系统的一些主要特征，以此分析工业自动化过程控制系统的发展趋势。

关键词：DCS,TDC200,TDC300,Experion PKS,控制网络,过程控制器,集散控制。

1 前言自从霍尼韦尔公司在1975年推出世界上第一套DCS系统TDC2000至今已经过去30多年的时间，过程自动化控制系统发生了巨大的变化。

回顾一下霍尼韦尔公司DCS系统的变迁过程，关注霍尼韦尔新一代Experion PKS系统，对我们了解当前DCS发展动态，把握将来的发展趋势具有非常积极意义。

2 霍尼韦尔公司DCS回顾2.1 TDC2000系统在1975年霍尼韦尔公司推出TDC2000系统以前，过程工业控制还处在过程仪表自动化控制时代，国外使用电动仪表，而国内还处于主要使用气动仪表，刚开始尝试使用电动仪表阶段。

生产过程对自动化控制要求相对较低，主要是保证生产稳定及相对安全运行。

无法或难以实现复杂控制，更谈不上先进或优化控制，生产效率相对较低，能耗大，产品成本高。

尽管这时已经出现了各种型号的计算机，并且很多人试图将计算机用于过程控制，但是由于没有很好地解决由于计算机故障而带来的生产损失和安全隐患问题，因而无法真正实现将计算机用于生产过程控制。

TDC2000的推出，其重要意义在于提出并实现了集散控制的概念。

集中操作和管理，实现各回路或设备之间更加协调运行，以提高生产运行稳定性和安全性；分散控制，实现危险分散和隔离，并且易于安装和维护。

30多年的实践证明，集散控制概念是计算机过程控制的一个基本原则。

这个概念不仅今天没有过时，而且在以后相当长的时期内都将是计算机过程工业控制的一个主导路线。

根据集散原则，整个TDC2000的基本功能分布特点是：控制网络采用单层冗余结构；操作站负责操作与处数据存储；不同的控制器实现不同的过程控制等等。

这种基本功能分布至今还被有些控制厂商的DCS所采用的。

二、系统概述 • 安全控制器和常规的PLC 有相似之处，它们都能完成逻辑和数学计算，都有输入输出卡件，对输入信号扫描并按照特定的控制逻辑驱动现场最终控制元件，也都有数字通讯端口。但是常规的 PLC 从设计上并不具备故障容错和故障安全的性能，这是它们的最基本区别。简要归纳安全控制系统的几个特点： • 它要达到两个重要目标： • 要有极高的安全性（Safety）和有效性（Availability），即使出现故障，也要用冗余等措施使系统工作正常。 • 着重内部诊断，将硬件和软件相结合，检测出系统本身的异常操作，检测出99%以上内部元器件的潜在危险故障；要采用一系列特殊的技术保证软件的可靠性；冗余配置，即使部件出现故障时也要保持正常操作；对通过数字通讯端口的任何读写要有非常高的安全可靠保证。 • 在系统设计时采用故障模式、影响和诊断分析，研究、测试系统中的每个部件会出现怎样的故障，以及系统怎样检测出这些故障。 • 要通过第三方的权威认证，比如TÜV 认证，以便满足国际标准对安全和可靠性的严格要求。

PKS操作站蓝屏快速恢复安装

PKS操作站蓝屏快速恢复安装摘要：大庆炼化公司润滑油联合装置的控制系统在2013年由TDC3000升级到PKS系统，在近几年的维护中，一个比较典型的故障是操作站硬盘死机蓝屏，这就需要对操作站的系统重新安装恢复。

本文主要针对快速恢复安装Console站的过程做了分析和讲解。

关键词：PKS；C站系统恢复；GHOST ；解绑定0引言大庆炼化公司炼油生产三部原有4套生产装置，2013年将霍尼韦尔的TPS系统升级为PKS系统，软件版本R410.1。

这4套生产装置的控制系统位于润滑油厂联合主控室内，共设置15台Console操作站。

1 PKS系统及其Console操作站的主要特点Experion PKS新一代的过程自动化系统，集成了过程控制、资产管理功能，融合当今最先进的控制、各种开放的工业标准、最新的计算机网络等技术，将过程控制和安全系统集成为一个单一且统一的结构。

PKS将过程控制网络分成三个层次，负责直接过程控制的节点（比如控制器和现场总线接口模块）连接到第一层。

Experion服务器、Console操作站和ACE 节点连接到第二层。

域控制器、厂房级优化器、DSA关联的Experion服务器以及PHD历史记录器连接到第三层。

Console操作站（C站）用于过程数据的监控与操作。

内部有RTDB数据库，但这种数据库只存储过程数据库，只有过程数据来自控制器，其它数据均来自服务器。

其优点是如果服务器故障可继续监控过程数据。

2操作站死机蓝屏分析在近三年的维护中，出现比较多也比较典型的故障是Console操作站死机蓝屏。

通常情况下Console操作站死机，重新启动或重新安装系统后可以继续使用正常运行。

但间隔一段时间该故障又会重复出现，严重时出现蓝屏现象。

对该故障机器硬盘本机硬件测试出现不识别现象。

操作站在过程数据的监控与操作过程中，与控制站和服务器之间需要有大量的数据进行交换，操作站的硬盘担负着大量的读写任务，不间断的进行着读写操作。
