  8. The Multi Phase Calibration Report was corrected to use the Site/Parameter ‘Calibration Precision’ setting in the cal results section.
  9. Several items were addressed with the parse utility and 8864 files; channel names over 8 characters will provide an informational error and the channel length need adjusted, the headers for the math channels changed and import logic corrected to match.
  10. The Monthly Sample Data Report had an issue addressed were parameter names were not included on subsequent pages when exported to CSV or HTML formats.
  11. An issue with dynamic scaling correctly toggling on the Sample Data Graph report was resolved.
  12. A Work Item rescheduling issue, when the next scheduled date landed on a day excluded in the item configuration, has been resolved.
  13. A display issue with AV Doc items attached to Work Item entries has been resolved.
  14. The ‘download’ logic for 8832s has been updated to use the highest configured Modbus timeout setting rather than ‘last in list’.

 

New Features

  1. The ability to add annotations has been added to the Calibration Data Editor. A Calibration Annotations report was also added to view the annotations.
  2. The AQS Text report coding has been updated so that it can be scheduled as a report to be emailed.
  3. A ‘View in Editor’ button / option has been added to the Information tab of the File Import Tool for launching the related editor after a file import has been run.
  4. A ‘Show Password’ option has been added to the set password screen so the text is displayed rather than asterisk.

  10. A new executive service component (Stream Listener Service) has been added for support of instruments like the Thermo GM-5000 and Picarro.
  11. Average Data Rollup now supports standard deviation and coefficient of variation for block type averages. Two were added to the general release (24h Coeff Of Variation & 24h Standard Deviation).  Contact support if you have needs for other block averages using these calculation options.

 

Site Node Logger

  1. An issue was resolved where changing a channel type could cause a problem with analog module voltage range settings.
  2. Code changes were made to address an exception that could show in the logs regarding CleanupTimerDelegate.
  3. Adjustments were made to the logic that checks for configuration changes and controls automated service restarts to apply them in order to reduce performance load on systems.
  4. An HTTP channel type has been added to support collection of certain values from the Teledyne T700 (or similar instruments with REST interface).

AirVision Version 4.3 (build 404) Release Notes – February 17, 2021

Issues Found and Resolved

  1. The Basic Sample Data Export report has been updated to show sample BLANK data as empty cells.
  2. The test button of the Email Service configuration screen has been changed to process through the AirVision server by default rather than directly from the client instance where ‘test’ is clicked. This will provide a truer test of function as the server is what actually sends out any emails as configured within AirVision.
  3. Pick list filtering was corrected for the Data Source Details -> Channel -> GSI tab display to address some valid GSI drivers not being shown in the list.
  4. Logger Download to 8816/32 loggers have a limit of 16 calibration phases but the AirVision editor would allow more if some were disabled and copy/paste was used. The logic has been corrected to properly limit max cal phases per sequence.
  5. Lat/Lon formatting was updated on the Site Configuration Report to avoid text wrapping.\
  6. A save issue when adding an Instrument Calibration was corrected.
  7. A labeling issue was corrected with the Data Value Format in the GSI/Modbus Drivers editor.
  8. Several errors that could be encountered when a file import template was set to use the ‘Save in Batches’ option have been resolved.
  9. The Monthly Sample Data Report has been updated to exclude blank samples from its statistics.
  10. When a user-customized violations of standards program type is defined with options ‘block’ and ‘backward’ selected, the ‘average type’ text on the report output was updated to correctly reflect the selected options.
  11. File Import option ‘Update Field Values’ logic was corrected to only change a field value if the value coming from the file is non-empty.
  12. Expected values for instrument calibrations and either expected value or value from constant is now required when importing a calibration to address possible import errors.

 

New Features

  1. Summary grids have been added to the System and Site levels within the Site/Parameter editor. Double clicking on the System level or one of the sites will bring up the summary grids.
  2. Ctrl+click and shift+click functionality has been added to the Group Permissions editor to make rights assignments more time efficient.
  3. The ‘notes’ field when assigning an asset are now included in the associated logbook entry.
  4. A Parameter MDL Editor has been added to allow quicker user editing of Minimum Detectable Limit, Instrument Detection Limit, Limit of Quantization, and Practical Quantization Limit for parameters.
  5. An AutoComplete function has been added to most grid style drop down lists within AirVision to allow the user to start typing in a field and automatically get ‘contains’ type behavior.
  6. The Database Export utility has been updated to exclude / filter AV Doc records in order to keep exports to a reasonable size.
  7. Assets now store certification information historically instead of just showing the most recent entry.
  8. Cal Standard asset types can now be associated with up to three parameters.
  9. A Reference Concentration field was added to Asset Tracking for type Cal Standard.
  10. MDL reporting for PAMS (Continuous Average parameter types) has been updated. If an MDL is set on the parameter in Site/Parameter, that value will be stored with new records. This can be disabled if need be by changing the UtilitySetting AutoSetPamsMDL.
  11. An ‘Exclude Template from Polling Status’ option box has been added to the Parameter Template Editor. Selecting this box will exclude parameters using that template from showing in the Current Polling Status report.
  12. Data Grade and Data Grade User Level editors have been added to AirVision. This is a QA / approval tool. If configured data grade drop downs appear in Average Data Editor, Batch Reading Updater form, and ADVP editor. Questions on usage / additional info should be directed to Agilaire support.

 

Site Node Logger

  1. The Site Node Logger Toolbox has been updated to fill the Time Stamp column in red if a value is missing but NOT in maintenance, calibration, or powerfail.
  2. An output pattern option is now available for calibration sequences (NOT instrument cal type) to send a ‘stop’ pattern to calibration so that if a cal is aborted via the 8872 the instrument can be notified.
  3. Logic that records the change of digital line states was updated so that only state changes are recorded in the database (eliminating duplication by recording same state entries).
  4. A new option is available for Modbus instruments – Combine Register Blocks in Requests. This checkbox on the instrument configuration screen of Data Source Details / Logger Channels will combine multiple register requests for an instrument even the if the register numbers are not sequential.  This option will reduce system overhead / unnecessary delays.

 

AgileWeb

  1. Several ‘kriging’ options for use with the Open Street Maps mapping option are now available in the Web Settings Editor. This provides a ‘contour mapping’ option of estimated AQI affected areas versus site-only AQI values.

AirVision Version 4.3 (build 263) Release Notes – October 13, 2020

Issues Found and Resolved

  1. An intermittent issue was discovered when users use Windows Remote Desktop to connect to a PC and then run the AirVision client on that PC via the RDP connection. Sporadic drops / reconnects in the RDP connection can trigger form load logic within the AirVision client.  That reload could cause a form to clear and IF the user then saved the configuration on that form could be deleted.  Code changes have been made to avoid this occurrence.  HOWEVER – Agilaire would recommend against RDP based running of the AirVision client wherever possible AND IF a form ever goes blank during a session CLOSE OUT THE CLIENT WITH NO SAVES.
  2. A change was made to the application logic to address extremely slow generation of pivot grid based reports (or reports timing out) that have row summaries. Ex. 24 Hour Averages Summary Report, Monthly Report, Daily Summary Report, Met Report
  3. A filtering issue on the AQS Text report when the Zero/Span Records option was selected has been resolved.
  4. A user filter on the Groups Editor was adjusted to reflect re-enabled users.
  5. The font size in the Entry Text field of the Logbook Entry Editor has been slightly increased for easier readability.
  6. Issue resolved where sorting users in the Email Notifications Subscriptions would falsely be interpreted as a configuration change.
  7. A constraint was addressed where an error could be encountered if a group was assigned to a task notification, the task deleted, then trying to delete the group.
  8. Spaces and special characters entered into constant names can cause issues during math calculations so the constant name field now rejects spaces and special characters.
  9. The Database Update Utility portion of the AirVision / AVTrend installer process now runs whether or not an existing database connection string exists (helps users when migrating servers / PCs).
  10. Polling of 8872s via the encrypted option could get stuck in the ‘running’ state due to a lack of timeout, this has been corrected.
  11. The Annotation Report was updated to acknowledge ‘new line’ behavior in displaying entries.
  12. When using the annotate option in Average Data Editor, Sample Data Editor, and in Annotate Data, the ENTER key / command is now treated as a new line / CR rather than triggering the OK button.
  13. A restriction has been removed where the Schedule Wizard in the Task scheduler would return an error when attempting more than 64 child tasks.
  14. An issue was corrected where users were unable to attach an AV Doc template item to a Work Item.
  15. A change was made to the Link to Logger emulation to address a command sequence only be sent over a serial/modem connection (or when polling and emulation ports are configured to the same value which suggests a serial end point) to avoid connection issues via TCP.
  16. A 3 minute pause (with a notification message to the user) was added to the 8864 when sending a cold start is selected in conjunction with other send options to address the much longer cold start time required by the 8864 vs the 8816/32.
  17. A fix was implemented to address incorrect parsing of EPOCH timestamps (affected imports with dates 6/15-6/18 of 2020).
  18. Data column corrections made to the AQ View report (California agencies).
  19. A filtering issue was resolved for the Modbus Instrument screen of Data Source Details.
  20. The option to archive only selected parameters has been restored in the Average Data Purge task type. A warning is in place if a user selects the archive option AND only selected parameters – Each additional archive task using a subset of parameters will use the same file names as the main ‘all parameters’ archive task, and will result in those files being OVERWRITTEN. It is necessary, if using multiple archive tasks on the same interval, to put each task’s archive files into a separate folder.  Contact Agilaire support with any questions on this prior to implementation.

New Features

  1. Converter Efficiency reports have been added for NO2.
  2. The AirNow/FTP editor has a new “Use Key File” checkbox that gets enabled if the SFTP Transfer Method. If this option is chosen, the Import Key File button can be used to import a SSH private key file. Primary development was for .pem key use for Sonoma Tech submissions.
  3. Filtering logic added to the GSI/Modbus Drivers editor to avoid user entry of invalid settings.
  4. Filtering logic and labelling improved on the ‘I/O’ tab of loggers to better assist users in error-free configuration.
  5. Added Expand All Subscribers / Collapse All Subscribers buttons to Email Notification Subscriptions editor.
  6. Two new options added to the AQI Program Editor:
    • Exclude From Final AQI – ignore this program in AQI Standard Report and AQI historical calc tool/task
    • Exclude From Realtime AQI – ignore this program in “current” applications like the Current AQI report, AgileWeb maps, and web service functions
  7. The rollup tool now consolidates repeated annotations so that rolled up intervals do not contain repeated annotations for each sub interval. If this behavior is undesirable to a particular customer, a Utility Setting is available to revert the behavior (RollUpAnnotationDistinctOnly).
  8. Filter logic added to the Modbus / GSI configuration area of channels to better reflect available drivers.
  9. Parameter Group and Site Group columns are now selectable within the Parameter Selection grid of the Data Analysis report.
  10. The Work Item Related AV-Doc Files list from the Work Item Editor has been added to the Work Items view. AV-Doc items configured in the Work Item Editor will show up in the Work Items view in a list. They can’t be added or deleted from the Work Items view itself. If the AV-Doc is configured as editable the “view” from the Work Items form will allow edits once it is launched, if the file is configured as read only it will only be viewable once opened and saves are prevented.
  11. ICS (calendar) support has been added to Work Items, allowing an export option via the ribbon buttons. Also, if notifications are sent from the Work Items Editor, ICS attachments will be sent with them.
  12. The bottom status bar of the AirVision client now lists the user name of the currently logged in user.
  13. Data Source Details now supports up to 64 calibration phases in 8864 loggers.
  14. The Annotation Report had Categories added to the selection criteria.
  15. Logbook polling / import logic has been updated to set a ‘locked’ status via the logbook editor once an addendum to an entry is made. The import would then ignore any polled logbook entries that matched an existing entry AND that existing entry has the ‘lock’ flag set.
  16. Average data rollup logic has been updated to populate the ‘Raw Value’ field IF the raw value is null at the time of the rollup execution.
  17. The Annotations and Audit Trail reports have been updated to include the site and parameter for each entry returned in the report.
  18. Additional logging was added to the file import logic and will show the file being processed in the Server Status display.
  19. A code change for improved performance was made that can affect any element displaying average data (Average Data Editor, reports, etc.).
  20. The ‘Description’ column has been added to the grid of the Asset Tracking editor.
  21. In the Work Item Editor, when a new item is added, if a site is selected the Asset pick list will be filtered by that site. The filter is ‘clearable’ if desired.
  22. Support has been added for email servers that require above TLS 1.0. The new utility setting (EmailSecurityProtocolType) is set by default to support SSL3 or TLS1.0/1.1/1.2.
  23. The Asset Assign function of Asset Tracking editor now allows the start and end date to be edited. These fields are also editable in the Assignment History area now.
  24. New options added to the Import Service in Server Configuration.
    • Scan Interval: How often to sweep the folders for files.  The default is 10s if NULL (this is consistent with previous behavior).
    • Scan Offset: Offset from the scan interval, to allow for X seconds after the minute or so forth.  The default is NULL which means no offset, so it will run on the even interval.
    • File Write Time Delay: The minimum time to wait after a file’s last write time before attempting to import it.  The default is NULL which means it will attempt to import the file regardless of the last write time (this is the same as previous behavior).   If this a value is set it will skip the file until the configured value time has passed.  If the file’s last modified time is less than the configured value during a scan, it will be skipped until the next scan.
  25. Fields for zero concentration data have been added to the Annual Performance Evaluation editor and report.
  26. An option to Cancel Task has been added to the Task Status view. It can be used at a group task level or on individual tasks.
    • Canceling a Group task will attempt to cancel any running child tasks, and will not start any further child tasks, but will continue in the “running” state until all of its child tasks are done/canceled.
    • This will work on most task types but not all support cancelation – SQL and sync tasks for example.
    • Polling tasks won’t immediately stop but will cancel whenever they finish whatever poll they’re waiting for.
    • Command-line task will attempt to stop the external program if it can.
  27. The task service of AirVision now scans all the task statuses at startup and checks for any that were still marked “Running” when the last shutdown happened. Any tasks left as “Running” status will be set to “Canceled” with a message that it was left in a running state at the last shutdown.
  28. Logbook logic has been updated so that once an addendum has been made to an entry, a ‘locked’ bit will toggle on that entry so that any repolling or importing of the same entry will not overwrite/remove the addendum.

 

Site Node Logger

      **Updated 8872 Instructional folder is available on the FTP site and should replace existing copies of the folder & documents**

  1. Changes have been made to help release system memory when the Interactive Calibration Tool is closed.
  2. When using the ‘Add Logbook Entry’ ribbon button from the Interactive Calibration Tool the Log Entry Time field is now not editable. The Event Time field remains editable on that form.
  3. A validity issue with asynchronous GSI vector wind channels was fixed.
  4. In the cases where an 8872 listens for polling over a serial port, constant pin changes on the port could cause CPU and memory use spikes. A code change has been implemented to address this.
  5. An issue where the Site Node Logger service would occasionally not write a configured value to an analog output has been resolved.
  6. Validity logic was updated for channel types (other than ‘rainfall’) so that the allowed number of readings is one less than the expected number of readings for the base average in order to correct < and > flagging during some power failure events.

 

AgileWeb

  1. Password updates made via AgileWeb now properly update the password set date on the users record.
  2. The Announcement Editor now allows for announcements to be set for specific sites in addition to ‘system level’ announcements.
  3. An option has been added to display a ‘Sites’ pick list above the map similar to the Regions and Layers lists.
  4. Options added to Web Settings Editor to restrict data range queries that can be executed via the website.
    • DateRangeSelectionControl_MaxDayCount: This controls the max number of days the calendar controls allow to be selected for any date selection in the app.
    • AverageDataQueryPanel_MaxDayCount: This allows override of the average data query panel, to limit it differently for average data reports and editor.
    • AverageDataQueryPanel_MaxQueryCount: This is the total number of estimated records to allow in the query for average reports and editor. It is the number of parameters times the number of intervals in the selected date range.  For example, to allow up to 4 parameters of hourly data for 1 day you’d set this to 96.
  5. Change applied so the announcement icon will show even if no title is entered.
  6. Announcement display area adjusted for less dead space around text.
  7. Clicking a site marker on the map will now bring up a condensed version of the site page. A link at the bottom of this pop-up will take the user to the full site page.
  8. Previously, hosting AgileWeb in a frame on another site would use the “/public” folder in the iframe source URL (to avoid the header, menu, login, etc.) or completely disable items via Web Settings Editor. There is an option now to add “?iframe=true” to the request URL and AgileWeb will substitute the master page from the public folder implicitly for that request.  This gives the option to keep the normal full site for intranet/logins/etc., while using the iframe mode for hosting the public page in another site.  EX:  http://localhost/AirVision.Web.Site/Modules/Maps/OpenStreetMap.aspx?iframe=true

AirVision Version 4.3 (build 4) Release Notes – February 27, 2020

  4. The TCP port field for Modbus instruments now supports value entries up to 65535.
  5. A setting retention issue when selecting the FC=6 option on a digital driver has been resolved.
  6. A channel type display issue was addressed on the Channel Configuration Report.

New Features

  1. AV-Doc is now fully enabled and available in AirVision for document management. Contact Agilaire support for an application note document on this feature if more information is desired.
  2. The User Editor has been revised to better reflect user account status and allow the re-enabling of users that previously required database editing.
  3. A ‘Created By’ field has been added to the Work Items editor.
  4. The AQS parameter code list has been updated.
  5. An option is now available to add a note when assigning an asset and these notes are saved with each assignment, displayed in the Assignment History pane.
  6. Several encryption options have been added to AirVision, supporting both client to server communications and data polling between 8872 loggers and server. **contact Agilaire support for more information if desired**
  7. The ‘Logger Download’ menu item has been renamed to ‘Send 8816/32/64 Program’ to more accurately reflect its function.
  8. To address issues where a single system has sites (especially 8872s) in multiple time zones, the application approach to determining site time was changed from using the System time zone value to use the Site level time zone value.
  9. An RMS option for Sigma Theta rollup is now available.
  10. New web API added to support JSON for average data

 

Site Node Logger

**8872s running Windows 10 operating system need to have a user managed Windows Update process in place.  Unlike Windows 7, Microsoft does not offer its customers full control of the update environment in Windows 10. Despite safe guards implemented in our Windows 10 image for the 8872s, Windows can still force updates after a period of time and the resulting forced reboots can affect the logger’s restart. Updates should be checked for and applied with personnel physically at the logger to account for any needed PC restarts, etc.  A two week schedule is recommended, no interval exceeding 4 weeks is advised.**

 

**Updated 8872 Instructional folder is available on the FTP site and should replace existing copies of the folder & documents**

  1. Changes have been made to help release system memory when the Interactive Calibration Tool is closed.

AirVision Version 4.2 (build 93) Release Notes – November 13, 2019

Issues Found and Resolved

  2. An issue with invalid data points not being hidden in the data graph when the ‘Show Invalid as Empty’ option was selected has been resolved.
  3. An exception issue when launching the Logbook Editor, Work Item Editor, Asset Tracking, or monitor assessment editors (introduced in earlier 4.2 build) has been resolved.
  4. An error received when attempting to import archived data back into AirVision has been resolved.     
  5. An update was made to file import logic for sample data types so that in an ‘update’ action existing flags were retained and any new flags added to the record.

New Features

  1. The AQS 2.2 Text Report can now include 15m interval data records. The POC shown for the 15m data will be the POC configured for the parameter under Site/Parameter plus 2 (ex. 1H POC is 1, 15m POC will be 3).
  2. A column displaying ‘Assigned To’ has been added to the grid display of the Work Item Editor.

AgileWeb

  1. A new ‘My User Info’ menu item is available upon user login so that basic account self-service can take place (password reset).
  2. Alternate naming for certain configuration criteria is now available. Use the Website Display Name field for site, parameter, parameter template, and unit name to have alternate content displayed on AgileWeb’s map and site pages.

 

AirVision Version 4.2 (build 57) Release Notes – October 17, 2019

Issues Found and Resolved

  1. The Start and End columns on the Sample Annotation report have been replaced with Sample Time.
  2. The logic used in the Average field of the Daily Parameter Report has been updated to match that used on the Daily Summary and Monthly reports for parameters with vector parameter templates assigned.
  3. Several configuration related tables have been added to the automated audit change tracking.
  4. The date and time format of the California specific AQ View report has been corrected to yyyy-mm-dd hh:mm:ss.

    • PasswordRequiresNumber
    • PasswordRequiresSpecialCharacters
    • PasswordUniqueLookbackCount
  4. The Line Status Report now notes if the line number is an Input or an Output.
  5. The ‘Data Grade’ column is now editable via the Average Data Editor. It was also added to the ‘Batch Edit’ option of the Avg Data Editor right click menu and the Batch Reading Updater data editor.

 

Site Node Logger

  1. The analog ranges of the ADAM 6017 modules can now be set and controlled via Input Range field on the Misc tab of the channel configuration. NOTE:
    • The Modbus ‘Instrument Model’ (as set in the Modbus Instrument configuration) must be 8872_AM
    • The individual driver entries (‘channels’) MUST HAVE the Input Index field filled in (should be equal to the channel ‘number’ plus one – Channel_0 should have index value of 1)
    • Once in place, manual changes to the Input Range in Apax Utility will get overwritten by settings in AVTrend once a service restart takes place
  2. The digital counter / frequency option of the ADAM 6066 modules will now automatically be set based on selection of a Wind Speed, Vector Wind Speed, or Rainfall channel type.
  3. The ‘Clear at Rolling Interval’ option for Rolling channels types has been corrected to function as on the 8832.
