      4.      Data Streams

      4.1     System Data Streams

      With GI.bench, data logging and visualization are possible on the PC level (in addition to Q.station loggers). To do this, you must first create the necessary data streams for each controller buffer containing the desired data. Data loggers and charts within GI.bench pull data from System streams or Merged streams.

      Click on the “i” icons for more information. For regular use, configure the following fields, as shown below:

      Name: Name of the system data stream

      Controller: Select the controller that contains the desired data (buffer)

      Stream: Select the controller buffer from which to create a system data stream

      Available Variables: In this menu tab, select the desired variables to be included in the stream

      4.2     Merged Data Streams

      If multiple system data streams exist within a project, they can be combined into a single merged data stream if desired. GI.data collects all data from the buffers of the controller(s) and merges their data into one merged data stream. Data loggers and visualization charts can pull their data from a merged stream.

      Click on the “i” icons for more information. For regular use, configure the following fields, as shown below:

      Name: Name of the merged data stream

      Cycle frequency: Sample frequency of the merged data stream (only divisors of the Streams 1..n)

      Count: Define the quantity (n) of system data streams to be included in the merged data stream

      Stream 1, 2, … n: Select each of the (preconfigured) system data streams to include in the merger

      Available Variables: In this menu tab, select the desired measurement variables from Streams 1..n

      4.3     Enhanced Data Streams

      Enhanced data streams allow for the creation of arithmetic functions (statistical variables) for processing data on the stream. Enhanced streams can be used for logging and visualization purposes, and they can exist on the PC and controller levels of the GI.bench project tree. Enhanced streams can be used in parallel with System streams and Merged streams, and can be configured with different data rates if necessary.

      TIP: You may create and define as many enhanced data streams as necessary; Gantner suggests creating several Enhanced data streams to capture data at different rates instead of adding additional data buffers (sample rates) to the Q.station. Doing so reduces the performance required by GI.bench and the Q.station.

      1. Right-click the Q.station controller in the project tree and select Add enhanced datastream

      2. Double-click the Data process under the project tree element, Enhanced streams, to configure it

      3. Define a Name and select the Source (buffer) and Rate (cycle frequency) of the Enhanced stream

      4. In the Calculated variables tab, select the Variables you wish to perform calculations on or include

      4.4     Arithmetic Variables (Enhanced Data Streams)

      Once the enhanced data stream is configured, you may add additional arithmetic variables for statistical analysis (e.g., min, max, standard deviation) to the stream.

      1. Right-click the Data process under the Enhanced streams element and select Add variables

      2. Select Variables to include in the stream and define the desired Additional arithmetic functions. Selecting Add statistical data will perform all four calculations (Min, Max, Average, and Std Dev).

      3. Double-click an arithmetic variable in the project tree to open the Variable settings

      4. In the General tab, you may change the Name of the variable.

      5. In the Formula tab, you may view or edit the Formula text of the Arithmetic variable. The Formula text is limited to 1000 characters. You may insert an arithmetic function into the formula text from the Functions drop-down menu by selecting the desired function and clicking Set at cursor. Click the small “i” button next to the Functions drop-down menu to view the relevant formula syntax.

      6. In the Reset tab, select Reset on logging interval to reset the calculated Min, Max, or Average on every logging interval (e.g. 1 min). Reset on variable utilizes an external variable to trigger a reset.

      5.      Data Loggers

      Q.station controllers have 20 configurable data loggers that function independently of a PC. Data loggers can also be configured on the PC level within GI.bench but require a System stream or Merged stream.

      5.1     Creating Data Loggers

      1. To create a data logger, right-click on either the PC or Controller level and click Add logger

      2. Double-click on the newly created logger, under either the PC or controller Data logging element

      3. In the Data logger settings window, select the Data source and Variables, then define the logger’s Name, Type, Rate, File length, Storage destination(s), Send FTP connection, and Enhanced settings. The Send FTP functionality is only available for controller-level data loggers (not on the PC level).





      4. In the Storage settings tab, you may configure up to 4 destinations per data logger. To add more storage destination fields, change the Destination count field in the Enhanced settings

      5. In the Send FTP logger settings tab, to select the FTP connection, you must first configure the FTP clients tab in the Controller settings Once configured, the FTP connection is selectable.

      6. In the Enhanced settings tab, select Automatically delete files to delete files when a destination reaches the configured files or bytes limits or full capacity.

      7. For Triggered and Event based loggers, you must configure the trigger variable(s), the relational operator(s), and trigger value(s) in the Trigger Triggered loggers can have a Start/Stop trigger, as well as Pre/Post triggers, specified in seconds or data sets (samples). Event based loggers have an Event (or Start) trigger and an optional Pre trigger specified in seconds or data sets (samples).

      8. To save the changes, select the controller in the project tree and click Write in the toolbar.



      5.2     Logger Settings

      Click on the “i” icons for more information. For regular use, configure the following fields, as shown above:

      Name: Define the name of the data logger, which appears in the name of logged files

      Logger type: Choose whether the logger is Continuous, Triggered, or Event based

      • Continuous logging initiates as soon as the project is activated and continues until its deactivated.
      • Triggered logging utilizes start/stop triggers, and pre/post trigger logging is available but optional.
      • Event-based logging uses a single trigger (or Event) with pre-trigger logging available but optional.

      Logger rate: Select a logging rate, only available for Continuous or Triggered loggers. The max. logging rate available is determined by the configured System sample rate available in Controller settings.

      File length: Define the max length of a data file specified in data sets (samples), seconds, bytes, or events. When the defined File length is reached, a new logger file is created as long as logging continues.

      Logging length: Define the maximum limit of the logger specified in data sets (samples), seconds, or bytes. When the Logging length is reached, data logging STOPS until the logger is triggered again. The value of File length cannot exceed the value of the Logging length for the Triggered logger type.

      Event length: Define the maximum limit of an “event” specified in data sets (samples), seconds, or bytes. Logging continues as long as subsequent events occur within the defined Event length. Multiple events can be stored in a single data file by changing the number of events in the File length field.

      5.3     Storage Settings

      5.3.1         PC Level Logger Storage Destinations

      Click on the “i” icons for more information. For regular use, configure the following fields, as shown above:

      Destination: Data loggers on the PC level log to internal paths on the PC. Configure up to 10 Internal Path storage destinations within the GI.service settings. Right-click the GI icon in the Windows System Tray and select Settings in the context menu. Go to the Storage Destinations tab and edit an available Index (0-9). Once an Index is defined in GI.service, that Internal Path is selectable in the logger settings. Only up to 4 Destinations can be configured per logger. To add additional destination fields, change the Destination count field within the Enhanced settings tab of the Data logger settings window.

      Subdirectory: Define the name of the folder that will contain the data in the Storage Destination (optional)

      Filename extension: Extension for the data file. The default extension is dat (per UDBF File format). The other extension option is csv (for CSV File format) but this format is limited to a logging rate of 100Hz.

      File Format: Choose either UDBF (binary format – Gantner proprietary) or CSV (configurable ASCII format)

      5.3.2         CSV Header Settings

      5.5     PC Level Logger Management

      1. In the Data Acquisition tab, click Logger(F6) in the toolbar. If no data loggers exist in the project, a prompt appears asking if you would like to create one. Clicking Yes opens the Data logger settings.


      2. If a logger already exists on the PC level, click on START to enable the logger. It will collect data immediately if Continuous, or when the conditions are met if Triggered or Event-based. Refer to the Actual file progress for the current status of the logger. Click STOP to disable the logger.

      3. The logger generates and saves either .dat or .csv files, per the logger’s configurations, to the specified directory, following naming scheme: [Recorder Name]_[Date]_[Time].[file extension]

      4. The .dat file extension is Gantner’s proprietary lightweight file format and can be viewed using the Gantner program viewer or converted to Ascii or CSV format using Gantner’s DecodeBin2Ascii tool. Both of these programs are available for free download on the Gantner Instruments website.

      6.      Data Visualization

      In addition to configuration and data logging, GI.bench offers data visualization and custom dashboards.

      6.1     Define Data Streams

      Data visualization occurs on the PC level and requires the use of data streams. You must create a System stream for each controller buffer containing the desired data. You may also combine synchronous data collected at various sample rates (i.e., from different system streams) into a Merged stream at one rate.

      Refer to Sections 4.1 and 4.2 of this guide for information regarding the creation and configuration of System data streams and Merged data streams.

      6.2     View Online Measurement Values

      In the Data Acquisition tab, go to Channels (F3) in the toolbar to view all variables. Click Start acquisition in the toolbar to activate the project. You must activate the project to view online measurement values.

      6.2.1         Edit Channel Groups

      Channel groups can be created in GI.bench to organize a project further. You may create custom groups to contain select variables of a project, or automatically group variables from each I/O module. You may then view the online measurement values of all channel groups by going to the Groups (F4) view in the toolbar.

      1. Click on Channel groups in the lower-left control panel to open the Edit channel groups
      2. In the Edit channel groups window, click the + icon to create a channel group or select an existing group from the drop-down menu and click the – icon to delete that channel group.

      3. You may click the Add group for each module button to quickly create groups for each module.

      4. To add variables to a group, select the group from the drop-down menu, then select the variable(s) you want to add to the group from the Available variables To select multiple variables at once, hold the Ctrl key when clicking. With the variable(s) selected, click the single arrow icon pointing to the right to add the variables to the group. To remove variables from a group, select the variable(s) you want to remove within the Variables in group list, then click the left arrow icon to remove.

      5. You may use the double right or left arrow icons to either add all available variables or remove all variables from a channel group. Click OK to save changes.

      6. In the Data Acquisition tab, go to the Groups (F4) to view the online measurement values of all channel groups. Click the + or – next to a channel group to expand or collapse the variable tree. Click Start acquisition in the toolbar to activate the project and view online measurement values.

Click on any variable in an element key to edit the Visibility, Display type, Line type, Line thickness, and Line color of that variable.

      5. You may also reposition any element on the dashboard by dragging it to the desired location. Resize an element by dragging the double-sided arrows at the bottom-corners of the element.

      6. To delete an element from the dashboard, click on the Trash icon at the top-right of the element. You may also click on the Gear icon for each element to bring up its respective settings menu.

      7. After completing any changes to the Chart Settings menu, click Apply and Save.

      8. Click on the X button above the Dashboard Designer to close it and lock all elements in place. You may still freely switch between dashboard tabs after the Dashboard Designer has been closed. You can open the Dashboard Designer by clicking on the 3 parallel lines next to Tab 1.

      9. With the dashboard elements locked in place, you may hover your mouse over an element and click the (“More Options”) button to Print the data or Save as JPEG, PNG, CSV, or UDBF.

      6.3.2         Personalized Dashboards

      You can include images in your dashboard(s) for a more personalized effect.

      1. You must first place the desired images in the following directory on your PC. Always make sure to use the latest version of GI.bench, available for free download on Gantner Instruments’ website.
        C:\Program Files\Gantner Instruments\GI.bench\V1.6.2.101_work_2019-11-07_10-20-44\gibenchwebui\lib\img

      6.3.3         Visualization QR Code

      GI.bench generates unique QR codes that any smart device can scan for a link to the project’s dashboards. The smart device performing the QR scan does not require GI.bench to be installed on it as the dashboards are accessible via the browser-based GI.benchWebUI. The device only needs to be on the same network. You may add and edit tabs from within GI.benchWebUI following the same procedures as used in GI.bench.

      1. To generate a unique QR code, click on Show QR code in the control panel at the bottom left.

      2. In the QR code for visualization window, you are prompted to select a network interface. Select the Gigabit Network Connection network interface (w/ IP address) from the drop-down menu.

      3. Once the network interface is selected, the QR code is generated and displayed in the window. The link provided by the QR code is also automatically copied to the PC’s clipboard. You may paste the link in a browser on the PC to access the dashboard via benchWebUI. You may also easily access GI.benchWebUI on the PC by clicking the Web Visualization button in the GI.service context menu.


      4. Assuming the smart device is on the same network as the PC, the QR code opens a browser page. You may add and edit tabs from within benchWebUI on the smart device or the PC by following the same procedures as used in GI.bench.


        Example (above): View and edit the dashboard via GI.benchWebUI on a PC on the same network


        Example (above): View and edit the dashboard via GI.benchWebUI on a phone in the network
