3 1. What is Guardian Software Update Delivery Service (GSUDS)? The Guardian Software Update Delivery Service (GSUDS) feature, available to Guardian Support subscribers, provides an automated delivery (either on demand or scheduled) of updates specific to the enrolled system including: DeltaV and AMS Device Manager Hot Fixes Microsoft Operating System Security Updates Text file containing the filename of the latest Symantec Anti Virus Updates tested for DeltaV NOTE: Emerson does not provide its end-users with a Symantec Antivirus software license. End-users will need to purchase this license from Symantec or their authorized distributors. Symantec Antivirus updates are downloaded directly from Symantec. McAfee Anti Virus patches (.DAT patch) DeltaV, AMS Device Manager and Ovation Device Install Kits HART, Fieldbus, Profibus and DeviceNet Device Install Kits Firewall Rule Updates The installed applet communicates and pulls update files from an Emerson server via the Internet. TIP: Look for these red check boxes throughout this guide. They identify important notes and useful tips related to maximizing the value of GSUDS. NOTE: Emerson does not provide its end-users with a Symantec Antivirus software license. End-users will need to purchase this license from Symantec or their authorized distributors. NOTE: The GSUDS applet is necessary for the successful implementation of the optional Patch Management service available for a fee through Advanced Services that allows for deployment of the said updates to the nodes across the DeltaV network. 2.

13 NOTE: An important note after downloading and Installing GSUDS. After downloading and installing GSUDS, set Internet Explorer as default browser. NOTE: IF using Windows Server When using Windows Server 2008, it is recommended to enable multiple logins to the machine to prevent download disruption in case a user logs in to the machine in the middle of the download. This can be done through the following steps: 1. To open Remote Desktop Session Host Configuration, click Start, point to Administrative Tools, point to Remote Desktop Services, and then click Remote Desktop Session Host Configuration. 2. In the Edit settings area, under General, double-click Restrict each user to a single session. 3. On the General tab of the Properties dialog box, uncheck the Restrict each user to a single session check box, and then click OK. NOTE: If running on Win NOTE: IF using Windows 10 Enterprise LTSB. To easily access GSUDS via Start Menu or Taskbar without searching for the application, please perform the following steps: 1. Go to Start Menu, All Apps, Emerson Process Management. 2. Right-click on Guardian Software Update Delivery. 3. Choose Pin from Start or Pin from Taskbar to pin GSUDS via Start menu or taskbar, respectively. 13

14 4. Getting Started Before being able to successfully download the necessary update files for your system, a couple of important tasks need to be completed. As seen in Figure 17 (also shown in Figure 18), the download folder location, where all the updates will be stored, should be identified, and a valid Guardian user should be configured. Figure 19. Prerequisites before using GSUDS. NOTE: To access GSUDS from Start Menu or access from the taskbar do the following steps. 1. Go to Start Menu > All Apps > Emerson Process Management. 2. Right-click on Guardian Software Update Delivery Service. 3. Choose either Pin from Start to access GSUDS from the Start Menu; or Pin from taskbar to access GSUDS from the taskbar. NOTE: GSUDS support McAfee AV Patches aside from Symantec as antivirus. 14

15 4.1. Download Folder Configuration Choose the location where the downloaded updates will be saved by selecting the Configure button and then clicking on the Change button, located in the Download Settings option (Figure 19). Simply browse through your hard drive for your desired location, and then click OK. Figure 20. Configuring the download folder. NOTE: Mapped Drives and Shared Network Folders. Downloading files into mapped drives and shared network folders is not supported. Please set your download folder to any local folder of your machine. 15

16 4.2. Adding a User Account GSUDS will only work if valid Guardian users are configured within the applet. To do so, click on the Users button in the Configured Guardian Users tab (Figure 19), then select Add New User in the drop down selection (Figure 20). Figure 21. Add New User. 16

17 A pop up window (Figure 21) will appear to ask for the username and password that is being used to login to the Guardian website. Figure 22. Input Guardian Username and Password. Click on Add User when done. Once the credentials have been verified, a confirmation window will appear (Figure 22). Figure 23. New User Added. NOTE: What will happen if the credentials are invalid? A user must have a valid Guardian account in order to use the GSUDS application. If inputs are invalid (wrong username or wrong password), the window in Figure 23 will display. If you forget your password, you may use the Forgot Password utility located in the Guardian login page. You may also contact your local Emerson office for assistance. Figure 24. Credentials invalid. 17

18 The valid user will then appear in the list of Configured Guardian Users (Figure 25). Figure 25. Configured Guardian Users. NOTE: An important note before downloading. Ensure that the PC clock is synchronized with the corresponding time zone in the PC where the applet is installed. If the clock is off by 10 minutes or more, the Emerson server will not accept the request from the applet for security reasons. 18

19 5. GSUDS Applet 5.1. Downloads The Downloads page is the main page of the GSUDS Applet. It will show the Installed Version, Last Download Date, Download Folder, Disk Space remaining and the number of configured users who are using the applet (Figure 26). Figure 26. Downloads Page. TIP: Download Folder Location. If the download folder label has three dot ellipses (i.e. download folder location is longer than the space provided), a user can hover on the said download folder path to view the complete path. TIP: Why is the Last Download date blank? A PC with a newly installed GSUDS applet will always reflect a blank Last Download date. A valid date will be displayed in that field if there were already previous successful downloads. 19

20 5.1.1 Test Connection Select the Test Connection button to check if the applet can connect to the Emerson web service. A connection status window will appear to check if connection can be established (Figure 27). Figure 27. Establishing Connection to Emerson Server. An information window in Figure 28 will appear if connection is successful. Figure 28. Connection Established. If connection cannot be established, a different window will inform the user of an unsuccessful connection to the Emerson server (see Figure 29). Figure 29. Connection Failed. 20

21 5.1.2 Downloads Select the Download List button (Figure 26) to view all the updates that are not yet downloaded and are currently matched to your DeltaV systems and devices based on the latest registration file uploaded to Emerson. If the window in Figure 30 appears after clicking the Download List button, there are no configured users in GSUDS that are identified contacts of any system. Figure 30. Configured users are not system contacts. NOTE: An important note before downloading. Downloading using the GSUDS applet can only be done if there is at least one configured user who is an identified contact of a DeltaV system. This contact can be a Software Contact, Safety Contact, Engineering Contact, Engineering SIS Contact, Other Contact, etc. To check the systems where a configured Guardian user is associated to, proceed to section of this User Guide. If the correct users are already configured in GSUDS, the list of updates can now be downloaded (Figure 31). Figure 31. Applet retrieving list of matched updates. 21

22 Once all updates have been received, a separate window, shown in Figure 32, will display all the necessary updates for the system. The types of updates are separated by tabs located in the upper part of the window. Figure 32. Download list window. NOTE: Selection of downloadable updates. The user can select the updates you want to download by going to the Configure tab and selecting the Requested Updates drop down list. See Figure

23 5.1.3 Download Now Select the Download Now link (Figure 26) to download all the updates from the download list. A snapshot of the download window is shown in Figure 33. Figure 33. Downloadable updates selection. NOTE: Important note on downloading. It may take quite a while for the download to finish if run for the first time. The reason for this is because the download list is being compared to the contents of the download folders in your hard drive, which at this point, are empty. 23

24 The difference of actual downloaded files and metadata is that actual downloaded files are those that will be installed in the system while the metadata contain information needed by automated Patch Management to determine which of these files will go to which node/workstation. Figure 34. Downloading status window. NOTE: Important note on failed downloads. A user may encounter failures in downloading some updates due to several unavoidable reasons, such as slow internet connection, server contention, etc., which the GSUDS applet cannot control. The user just needs to click on the Download Now button again to get these failed updates. ONLY those that failed will be downloaded since the download folders already contain the updates that were successfully downloaded by the applet. Once the download is complete, the files downloaded will be in the download folder specified in the Configure page. The GSUDS applet also creates subfolders (Figure 35) in the download folder necessary to easily manage and separate the downloaded files. Figure 35. Subfolders. NOTE: Scheduling Downloads. For Windows 2008 and Windows 7, the GSUDS can be scheduled by going to Start > Programs > Accessories > System Tools > Task Scheduler. 24

25 5.1.4 Configuring GSUDS as a Scheduled Task A. Upon installation of GSUDS ver. 6, a pre-defined scheduled task will be created for automated GSUDS run. Figure 36. GSUDS Scheduler Properties. General Tab z Task Name: Emerson GSUDS z Author: {Current User} z Description: Launches GSUDS in silent mode and downloads configured software updates. z Security Options -- When running the task, use the following user account: {Current User} -- Run only when user is logged on is selected Triggers Tab z Trigger One time z Details {trigger will start after 24 hours from the time GSUDS was installed} z Status Disabled Actions Tab z Action Start a program z Details {path to GSUDS.bat} 25

26 B. The user needs to Enable the trigger set in the scheduled task in order for it to execute. Figure 37. GSUDS Scheduler Properties: Trigger Tab. 26

27 Figure 38. GSUDS Scheduler Properties: Pre-configured Trigger Settings. C. In order to make the scheduled task run when the user is logged-off, you need to set the ff. General Tab z Security Options -- Select Run whether user is logged on or not -- Check Run with highest privileges Upon clicking OK, you will be asked to enter your password. 27

28 Figure 39. Enable GSUDS Automated Run Even If User is Logged-Off. D. GSUDS.bat will be installed in the current user s My Documents folder: Ex. C:\Users\{Current User}\My Documents\Emerson GSUDS\ E. Aside from GSUDS.bat, RunGSUDS.exe will also be installed in the My Documents folder. This will be called by GSUDS.bat and will be used for silent download in Windows Server 2012 when the user is logged-off. Clicking RunGSUDS.exe will just open the GSUDS application. NOTE: There should only be one scheduled task for running automated download via GSUDS. 28

29 In addition, please make sure that is included in the list of Trusted Sites for your computer. To validate this, go to Control Panel and click on Internet Options. Go to the Security tab of the window as shown on figure 40. Figure 40. Internet Options. Please make sure that the schedule for GSUDS download does not conflict with other scheduled tasks. Ensure that only the GSUDS task will run during the specified schedule. 29

30 NOTE: Applet behavior when the auto-download scheduling is enabled. For Windows 2008 and Windows 7, the GSUDS can be scheduled by going to Start > Programs > Accessories > System Tools > Task Scheduler. 1. The applet is placed in the system tray (see Figure 41) and closes itself after the download (that is if still in the system tray after the download finishes). Figure 41. GSUDS applet in the system tray. 2. If the applet is idle and in the system tray when the auto-download is triggered, the applet will proceed with the auto-download. 3. If the applet is idle and NOT in the system tray (meaning, the GSUDS window in figure 18 is open), NO auto-downloads will be done unless you select the Download Now button. 4. When GSUDS task scheduler is configured as run whether user is logged on or not, it will not be visible in the system tray if the scheduled task executes. If Run user when logged on is selected, GSUDS will show only on the system tray. 5.2 Configure The Configure page is where you can configure the Guardian users who will use the applet and the location where the downloaded files will be placed Configured Guardian Users As seen in Figure 42, the Users drop down list shows the options used to configure GSUDS users: Figure 42. Configure Guardian Users. 30

31 Add New User: See section 4.2 of this User Guide Edit Selected User: Click Edit Selected User to change the login credentials of the selected user in the list. Doing so will open a popup window (Figure 43), which will ask for the new address and the user s corresponding Guardian password. Click on Update when done. Figure 43. Edit address. NOTE: Configured Guardian Users. The login credentials, (username and password) used in the Guardian website and the GSUDS applet must match. If they are changed in Guardian, they should also be changed in GSUDS by selecting the Edit button. Failure to do so will result to possible errors during download. Remove Selected User: Click Remove Selected User to delete the address from the list of Configured Guardian Users. View Systems: Click View Systems to see the system IDs the highlighted address is associated with, i.e. user with the address is a named contact of the system ID. See Figure 44. Figure 44. Systems associated with address. NOTE: System selection for GSUDS. The systems shown in Figure 44 are the systems where the selected user is an identified contact. The user can choose to download all updates either for all systems or for several systems by placing checkmarks on the appropriate systems. Make sure that the Save Settings button is clicked. 31

32 Refresh: Click Refresh if there are changes made to the profile of the addresses in the list, such as the user being added as a Safety Contact for a system ID. It is advised that the Refresh be used after such changes, so the application can revalidate and refresh the account information within GSUDS (Figure 45). Once all information has been revalidated, a confirmation window will appear, as seen in Figure 46. Figure 45. Refresh Guardian user credentials. Figure 46. Credentials confirmation. Proxy User: Click Proxy User for setting up the GSUDS applet to be used for downloading updates behind a proxy server. Tick on the Enable proxy credentials in Figure 47 and provide the username and password. Figure 47. Enter proxy credentials. 32

33 NOTE: Using the Proxy Settings. To check whether a proxy server is required for internet access, open the Internet Options window (Figure 48) in Internet Explorer by clicking on Tools > Internet Options. Choose the Connections tab and click on the LAN settings button in Figure 49. Figure 48. Internet Options. Figure 49. Internet Options Connections tab. The LAN Settings configuration window (Figure 50) will be displayed. A checkmark on the Use a proxy server for your LAN means that the internet connection uses a proxy server specified in the Address and Port fields. Figure 50. LAN Settings window. NOTE: GSUDS Proxy credentials vs. IE Proxy server. The GSUDS Proxy credentials in Figure 47 MUST be enabled if the Internet Explorer Proxy server in Figure 50 is enabled. 33

34 5.2.2 Download Settings As mentioned in Section 4.1, it is a requirement to define the hard drive location where files will be downloaded before being able to successfully download updates. As covered in Section 5.1.2, the user can select the updates he/she want to download by going to the Configure tab and selecting the Requested Updates drop down list (Figure 51). Figure 51. Download and Update Settings. 5.3 View Logs The View Logs page is where the Installation Help files and the Applet Log files can be downloaded and viewed (Figure 52). Figure 52. View Logs page. 34

35 5.3.1 Installation Help Files NOTE: Important note on installation help files. The hotfixes and updates must be already downloaded to your hard drive because they are being used to generate such files. The user can choose any of the update types to view its respective installation help file. See Figure 53. By clicking on the View File button, the user can find all the information necessary to properly install the downloaded files to the respective nodes. Figure 53. Different Installation Help files. 35

36 NOTE: Add GSUDS as a trusted site. If running on Windows 2008 and the security window (see Figure 54) appears during the generation of the installation help file, click on Add to include GSUDS as a trusted site. Figure 54. Add GSUDS as a trusted site. TIP: Getting a copy of the installation file. A hard copy can be obtained by clicking on the Print link located at the upper right hand corner of the installation help file window. A soft copy can also be saved on the hard drive by selecting the Save to file link (htm format). NOTE: Downloading Symantec antivirus definition files. Updates for Symantec Antivirus pattern files are downloaded directly from Symantec using the LiveUpdate Administrator (LUA). Emerson does not provide these antivirus update files. These files undergo compatibility checks performed by Emerson once a month. Please note that the GSUDS applet only provides a text file that identifies the latest Emerson approved Symantec Antivirus pattern files. These text files are used to download the correct anti-virus updates from Symantec. NOTE: About Symantec Antivirus Software licenses. Emerson does not provide its end-users with a Symantec Antivirus software license. End-users will need to purchase this license from Symantec or their authorized distributors. 36

37 5.3.2 Applet Logs The GSUDS applet provides two types of logs: Activity Logs and Error Logs, and these logs are different from one installed applet to another. The Activity Logs in Figure 55 let the user view the recent activities that were generated in the application. Such activities include validation of configured users, update files download status, change in applet configuration, etc. Figure 55. Activity Logs. The Error Logs show a list of the errors encountered in the applet, such as failure to get help files, failure to connect to an Emerson server, etc. See Figure 56. Figure 56. Error Logs. 37

38 TIP: Saving updates list. Click on the Save to file button shown in Figure 55 and Figure 56 if you wish to save the list in an XML file. Select the location where the file will be saved, provide a file name then click on Save. See Figure 57. TIP: Failed Downloads. As previously stated in Section , failures may be encountered in downloading some updates due to several uncontrollable reasons. If a user checks these error logs and sees downloading failures, it is suggested to click on the Download Now button again to ensure that all updates are indeed downloaded. Figure 57. Saving the updates list. The user may choose to archive these log files on the hard drive by selecting the Purge Logs button in the View Logs window, as shown in Figure 58. This will also clean up the download folders of unnecessary update files. Figure 58. Purge Logs. 38

39 5.4 Help/Support The Help/Support window, shown in Figure 59, provides information on where to get support for the GSUDS applet. There is a link to the Guardian Dashboard website as well as the SureService website for the user s convenience. A copy of this User Guide document can also be downloaded or viewed by selecting the User Guide button provided. Figure 59. Help/Support Page. 39

40 6. Uninstalling the GSUDS Applet As with any other Windows program, the GSUDS applet can be uninstalled using the Add or Remove Programs (see Figure 60) or Programs and Features (for Windows 7 and above Figure 61) in the Control Panel. Figure 60. Programs and Features. Once the utility finishes populating the list of installed programs in the PC, scroll down until the Guardian Software Update Delivery Service program is displayed. Select the application then click on the Change/Remove button. See Figure 61. For Windows 7 and above, right-click on the Guardian Software Update Delivery Service program, and select Uninstall/Change. Figure 61. Programs and Features. 40

41 Select Remove the application from this computer option in Figure 62 then click on OK. Figure 62. Select GSUDS from the list. Follow the on-screen instructions in Windows until the GSUDS applet has been successfully uninstalled. Figure 63. Remove GSUDS. 41

42 7. Restoring the GSUDS Applet Restoring the applet to a previously installed version may be necessary if you are encountering problems with the version currently installed on the PC. This can be done by selecting the Restore the application to its previous state shown in Figure 63. This option is not available if the applet is newly installed. It is only possible if the applet has been upgraded at least once. 8. Upgrading the GSUDS Applet If applet is closed and is started from the Start Menu and a new version is detected by GSUDS, a user will be able to see a window similar to Figure 64. NOTE: Upgrading GSUDS. For GSUDS version 5.0 and below, the applet would need to be uninstalled first before upgrading. Please make sure that you are at GSUDS version version and above to enjoy automatic GSUDS version upgrade. GSUDS can be configured to automatically update or not. z If automatic update is set, GSUDS is automatically upgraded to the latest version. z If automatic update is not set, user is presented with the Changelog and option to Update Now or Update Later. All updates are necessary; which means doing an Update Later makes GSUDS unusable. NOTE: Upgrading GSUDS It is highly recommended to click on Update Now as seen in Figure 64 to upgrade the GSUDS Applet. Figure 64. GSUDS Update available. 42

43 After clicking Update Now, GSUDS will update then a pop-up message will be displayed. Figure 65. GSUDS Applet has been updated. For changes to take effect, click OK. GSUDS is restarted and upgraded to the latest version. 9.
