TrendMgr

The TrendMgr taskis the manager process for the trending subsystem.

TrendGsm

The TrendGsm task is responsible for trending data from global shared memory.

TrendSrv

The TrendSrv task is the server process for delivering trended data to trend clients across the network.

TrendTrig

The TrendTrig task [LINK] is the main process for the historical trending subsystem.

GsmExpSvr

The GsmExpSvr task [LINK] is the server portion of the software-based reflective memory subsystem, discussed in the Data Transfer section.

GsmExpRcv

The GsmExpRcv task [LINK] is the client portion of the software-based reflective memory subsystem, discussed in the Data Transfer section.

GsmPifBld

The GsmPifBld process [LINK] is responsible for building the data dictionary program information files before starting the Tsentry system, discussed in detail in the Data Dictionary section.

Before tasks and screens can be created a new system must be generated. Start up tpriNtRtAdmin and then perform the following actions:

1. Enter SystemID and System Name, e.g. ‘Demo’ and ‘Demo Development System’

2. Click ‘Generate New System’

3. A list of steps for creating the demo system is displayed; those items that are checked have been automatically finished, those that are unchecked must be performed manually.

   If this is the first time you are configuring a system on your machine, you need to manually do each of the steps following. If you have already configured a system previously, then only building the data dictionary is necessary

   1. Configure DCOM as required by your system, either Windows 2000 [LINK] or XP/2003 [LINK].

   2. Configure Internet Explorer [LINK] as required by your system.  Note that depending on your system you may not need to perform all items.

   3. Verify wwwroot virtual directories (My Computer | Manage | Services and Applications | Internet Information Services | Default Web Site | Tsentry)

   4. Open the main Tsentry menu (http://127.0.0.1/Tsentry), click on the HMI Setup link, and follow all instructions on this screen.  Once this is complete, you can return to the main menu to try any of the standard Tsentry screens (Probe, TrendX, etc.)

   5. Customize Data Dictionary TsentryHelp | (Data Dictionary) - use the created Visual Studio solution in the D:\locNtRt\sys\Tasks directory and 'Build | Batch Build | Check DemoDataDictionary | Rebuild'.

Screens are used to display and modify values using a wide variety of visual tools. The combination of these tools yields a powerful and fully customizable real-time graphical user interface. To build a new screen, follow these steps:

1. Run tpriNtRt administrator program D:\locNtRt\tpriNtRt\Apps\tpriNtRtAdmin\tpriNtRtAdmin.exe

2. Enter Screen Name, e.g. ‘DemoScreenXX’ where ‘XX’ is a unique number (must be unique so your screen doesn’t conflict with anyone else’s screen)

3. Click ‘Generate New Screen’

4. A list of steps for creating the demo screen is displayed; those items that are checked have been automatically finished, while those that are unchecked must be performed manually.
