1 IntroductionDataLink/AQM is a Data Acquisition Software package for environmental monitoring andmeteorological study that maintains tradition for the tenured environmental professional.The software allows direct or modem connection to H2NS, or a variety of othermanufacturers, data loggers.

Key Functions:• Automatic or manual polling of interim and/or final data from multiple data loggers

(stations) at multiple locations at customer determined frequency and times.• Automatic alarm flags to alert operators of out of spec performance.• Automatic or manual reporting of custom configured reports from multiple data

loggers.• Multi Station/Multi Channel Trend Charts in Line, Bar, Area and/or 3D formats.• Wind Rose Plots• Alarm and Calibration documentation• “Real Time” access of instantaneous data, as often as every ten seconds, in a

variety of formats: Meters, Bar Charts, Trend Charts and Tabular summarieswith max/min, interval averaging and totals in a separate “Real Time” database.

• Real Time and Terminal Mode access to configured data loggers.• Hot Button access to set/unset data logger digital status bits and relays.• Pass through access to serial port Instrumentation for monitoring, configuration,

calibration and troubleshooting.• Edit and/or export Final and Interim nonproprietary databases to popular spread

sheets and applications (e.g. Excel and Access)• Ease of set up by automatically passing data logger configuration in either

direction.

This manual describes how to customize and use DataLink/AQM to monitor and controldata loggers and attached instruments and obtain accurate, timely, and tailored data,reports and charts.

2 Software Installation

2.1 System RequirementsThe minimum system requirements for running DataLink/AQM are:

• Pentium 233 or better processor• Windows 95, 98, 2000, ME, NT4.0, XP• 64MB Ram• 33.6K Data/Fax Modem (56K V90 recommended)• 2.4GB Hard Drive or Larger• 600 x 800 pixel minimum SVGA Monitor• Color Printer, Optional (recommended)

2.2 InstallationOpen the computer’s CDROM tray. Insert the DataLink/AQM distribution CDROM andclose the tray.

Prior to installation, make a copy of your DataLink/AQM distribution CDROM. If aCDROM “burner” (CD/RW drive) is not available, copy each of the “disks” (directories)on the CD to individual 3.5" diskettes. Number the diskettes sequentially. Store them ina secure, climate-controlled area. While this step is not necessary, it is good practice.

Select "Start", "Run" then "Browse".

In the "Browse” window double click your CDROM drive (D:, E:, etc.).

Double click "Disk 1."

Select startup and click OK.

The serial number of the software is on the CD label and on the CD jewel box carrierlabel.

3.2 Update a DataLink/AQM Station ConfigurationIt is often necessary to update station configuration information after the station hasbeen given a short station ID (name) on the main data link page. In fact, it must be doneduring initial station configuration as will be discussed later (Section 3.3.3).

3.2.1 Modify an Existing DataLink/AQM Station ConfigurationIf DataLink/AQM is not running, double click the DataLink/AQM icon on your desktop toopen the program (Figure 3-1). The main DataLink/AQM screen (Figure 3-2) appears.

In the left panel, highlight the abbreviated Station Name of the data logger to beupdated.

On the menu bar at the top of the screen, select Station and then ModifyStation.

Enter a password, if necessary, in the Station Config pop-up box and click Ok (Figure3-4). The Station Configuration window appears.

3.2.2 Creating/Changing a Password for ConfigurationModification

The first time a station is opened after it is created; no password is required to modifythe station configuration. To add or change a password, begin to open the station asdescribed above. However, rather than clicking the Ok button; click the Change buttonin the lower right hand corner of the password window (Figure 3-4).

Figure 3-4 Station Config Pop-up Box

In the Change Password pop-up box, enter the old password (or skip to the first newpassword box if there is no password). Enter a new password in the second box. Enterthe new password again in the third box to assure it was entered correctly the first time.Then click Ok (Figure 3-5).

Once a password has been assigned, a user has three chances to enter the correctpassword before clicking Ok or the System Config screen will automatically close.

3.3 Configure a Data Logger Station in DataLink/AQMThe Station Configuration window appears when Ok is clicked in either the Add NewStation window (Section 3.1) or the Station Config window when Modify Station isselected (Section 3.2.1). The Station Configuration window has nine separate tabs forstation configuration information. The Info tab is the default tab when the StationConfiguration widow first appears.

3.3.1 Info Tab (Figure 3-6)When the Info tab is active, Basic Station Information appears in the tab identificationblock above the tab row.

The Station Name on this screen is the name that will be attached to all data recordsand reports. This name is an expansion of the abbreviated name used when the stationwas set up as a “new” station. It is a descriptive name such as “Austin Met Tower”, “6th

street Ozone”, etc. Simply type the Station Name (limited to 30 characters) in the box.

If you plan to automatically poll the station for data (usually the case), click the EnableQueue check box.

For further identification, enter the station’s physical address in the Station Address box(optional).

Next, click the Logger Type drop down box; highlight the appropriate logger (CPP-3794or DSM3260), and click.

Enter Old Password(if any)

Enter NewPassword Twice

Figure 3-6 Station Configuration Info Tab Screen

If a DSM is selected, a Unit ID drop down box appears. Click the drop down box,highlight the appropriate $ ID for the DSM (i.e. $1) and click.

If a CPP is selected, three areas appear. The Unit ID drop down box defaults to "h". Ifmore than two CPPs are at the same site, sharing the same Communication Line, thesecond CPP would have an ID of “i”, the third “j”, etc. The Hangup ID drop down boxdefaults to “u” and should not be changed. The CPP 3794 ID defaults to “010”. This isalways its identifier and should be left intact.

3.3.2 Connect Tab (Figure 3-7)While in the Station Configuration window (Section 3.3), click the Connect tab.Connection Information (RS232 & Tel) appears in the tab identification block abovethe tab bar.

In the Type section, click the 1. Dirct Connect or 2. Modem Dial Up radio button, asappropriate.

If a modem is used for connection, the standard modem “AT” command set will appearas the default in the Modem Init String (AT-command to modem) section. However,the option exists to enter another string if necessary. Older modems (1200-2800 baud)sometimes have difficulty connecting to the modern 56K baud modems. It may benecessary to enter a unique command set for older modems to “shake hands” with anewer modem. When difficulty has been encountered in these circumstances, an “AT”command set that has been successfully used is “&FE0Q0V1&C1&D2S0=0&N2”.

In the Dial section click the appropriate radio button for either Tone (the default) orPulse dialing. Enter the phone number of the modem at the station site in the LoggerTelephone Number box.

If necessary, complete the Com Port Init String ( sent after modem is connected )section of the window. Consult the switch manufacturer’s documentation for the correctstring and the correct delay times.

3.3.3 Download Data Logger ConfigurationIf data was not available on an INI file to configure the new station in Section 3.1, it isnecessary to retrieve the configuration of the data logger at the physical station beforecontinuing with the DataLink/AQM Station Configuration. Therefore, suspend the datalogger configuration by clicking the close (“X”) button in the upper right hand corner ofthe screen. Section 4.3 describes how to retrieve the data logger’s configuration.

After the data logger’s configuration has been downloaded return to data loggerconfiguration by following the steps in Section 3.2 above.

Alternately, you may import a station configuration from an existing data logger set upexactly as the “new” logger is to be set up. This configuration can then be uploaded tothe “new” data logger. To use this function see section 3.3.10. However, it is almostalways better to download the data logger’s configuration directly from the logger(Section 4.3).

3.3.4 RealTimeMode Spec. Tab (Figure 3-8)DataLink/AQM allows data to be displayed in a “Real Time” mode. The data displayedcomes from a unique set of “real time” records separate from the main polled data base.This section defines how a separate “real time” database is be created by downloadingcurrent actual, not averaged, readings from the data logger at specific intervals. Whenoperating in “real time” mode, the mode is suspended when it is time to automaticallypoll the regularly scheduled final or interim data for the main data base. Once the poll iscompleted, DataLink/AQM automatically returns to “real time” mode. See Section 11 fora complete discussion of the types of “real time” displays available.

While in the Station Configuration window (Section 3.3), click the RealTimeModeSpec. tab.

16

The Real Time Update Rate is the frequency at which data displays are refreshed(whether standard data has changed because of a new poll or not). It controls howquickly current data is displayed. DataLink/AQM defaults to an update rate of 30seconds. Enter the time you deem appropriate, recognizing that the fastest effectiverefresh rate is every 10 seconds.

Figure 3-8 Real Time Mode Specification Tab Screen

The Max Real Time Record # is the largest number of records which will be kept in the“real time” set of data used for display. The data set is a “snapshot” of actual data anddoes not include averaged data. As new records are added, the oldest records areremoved. The maximum number of records is selectable from 1 to 10,000 (sufficient tohold over 27 hours of 10 second data). Since Real Time data is used solely formonitoring immediate performance, and final and interim data is the data of record, it isnot necessary to maintain an extensive “real time” data base. Select a number ofreadings that allows sufficient data for the Real Time displays to be configured in Section11. For example, setting an update rate of every 10 seconds would create 6 records perminute. If a trend chart of real time data is created for an hour of data there would needto be a minimum of 360 records (60 minutes x 6 records/minute).

The real time data file is stored in the station folder and identified as StnRT.dbf. Thistype of file is easily imported into spreadsheets such as Excel, Access, etc. Theexample in Figure 3-8, displays data every 10 seconds and the “Real Time” data set islimited to 1000 records, or approximately 2 ¾ hours of data.

While displaying data in “Real Time” mode, data is polled for final and interim data, asdescribed above. The Data Retrieval In RealTime Mode area allows selection of theinterval and timing the data logger is polled.

In the Retrieve Data Every…Min box enter the desired polling interval. Figure 3-8shows each 10 minutes. In the Start at … minute in every hour box enter the first timeafter the hour to begin the polling cycle. For example, if the “start at” minute is set at 5,and the “retrieve data every” interval is set at 10, interim polling will take place at 5, 15,25, 35, 45, and 55 minutes past the hour. Be sure to select "start at" time that will notinterfere with "Daily" activity times.

The Synchronize Clock section determines how time drifts between devices will berectified. Each time polling takes place, the clocks on the PC and the data logger arecompared. While the data logger is a very accurate timekeeper, most installations willselect the PC clock as the Master. This means that if the PC Master radio button isselected the data logger’s clock is reset to whatever time the PC says it is if there is adifference greater than specified in the Sync if Difference greater than box (the default is30 seconds). If Logger Master radio button is clicked, the data logger will reset the PCclock if there is a difference greater than specified. If the No ReSync (Check Only)button is selected, neither clock is reset. However, if a time drift greater than thetolerance value selected occurs, DataLink/AQM generates a “Time Drift” alarm andrecords this alarm to the Alarm Database.In the Synchronize at … o’clock section select all the hour’s buttons for the hourswithin which you want polling to take place. Avoid hours where periodic calibration orother functions that should not be interrupted are accomplished

3.3.5 Memo Tab (Figure 3-9)The memo tab is used as a log for useful messages and/or reminders.

3.3.7.1.1 DataBase FolderThe DataBase Folder section of the tab is where the final averaging interval is set.While the data logger collects data every second, the “Final Average Interval” is the timeover which the interim readings will be averaged to create the average data of record(final average data). In the Period (min) box put the number of minutes to be averaged(usually 60; hence “hourly”). This value must match the Final Average Interval set up inthe data logger’s configuration (15, 30 or 60 Minutes).

In the Retrieve Data drop down box highlight and click “yes” or “no”. If “no” is selected,no final average data will be collected when the data logger is polled.

3.3.7.1.2 DataBase Files ModeThe DataBase Files Mode section of the tab is where the database folder structure isselected for both the Hourly (Final) data and the Auxiliary (Interim) data. The files aresaved in standard “.dbf” data base file format. Any standard database manipulationprogram such as Excel or Access will open these files.

Hourly and Auxiliary report data are stored in the station folder and may be stored in onecontinuous file or may be divided into separate monthly files.

If the [C] Continuous (All in 1 Dbs) radio button is selected, the Hourly and Auxiliaryreport data files will be stored as C:\DataLink\Shortstationname\Hrept.dbf andC:\DataLink\Shortstationname\Auxrept.dbf respectfully.

If the [M] Monthly Based (separated Dbs) radio button is selected, a separate folder iscreated for each calendar year within which a folder is created for each month. Forexample, hourly data for May 2003 would be stored in a file namedC:\DataLink\$MonthlyDataBase\2003\05\Hrept.dbf).

The mode of storing files may be changed at any time. The new mode may begin “as ofnow” or may include all existing data in the new mode. For example, to change fromstoring files in monthly folders to continuous files without including previous records inthe new continuous files, click the [C] Continuous (All in 1 Dbs) radio button. Tochange to continuous files and include existing records in the file, click the CombineFiles [M] >> [C] button.

It is important to note that when the database file mode is changed the files, as theyexisted, will remain in the station’s folder, but will no longer be maintained. They willforever remain as they were, unless the file mode is changed back again.

3.3.7.1.3 Data ExportThe Text File Output section of this tab (and the same section of the Aux (Interim) tab)sets parameters for extracting and exporting selected data, in custom configured textfiles, from the polling computer’s data files to any desired location available on thepolling computer’s network such as a central repository or an operator or supervisor’spersonal computer. The extracted file is a delimited ASCII text file created from the datafiles created during regular polling of the data logger.

While on the Hourly (Final) tab, use of the Text File Output section will define Finaldata. If on the Aux (Interim) tab, the Text File Output defines Interim data. Thefollowing data selection steps are the same for both tabs.

To automatically export data after each poll, click Export Text File OutPut check box. Ifthis box is left blank, data can be extracted in “manual” mode.

Next, click the View/Edit Rule button. A new Text Output Rule / Channel windowopens with four additional tabs to allow you to configure “automatic” or “manual”exported data.

3.3.7.1.3.1 Output Rule / Channel; Type / Naming Rule Tab (Figure 3-12)The Record saved as: section allows selection of LAST record Only or Append to theexisting file by clicking the appropriate radio button. Selection of Last record Only willoverwrite previously extracted data with new data from the latest poll. Selection ofAppend to the existing file will add data to previously extracted data.

The Data Source section of the tab allows selection of either Actual (as collected) dataor Modified data if the extraction is being conducted manually. Only Actual data isavailable when automatically creating files during polling.

The OutPut File Naming Rule section allows for the selection of various sub- directorypaths and file naming conventions to separate data files into meaningful organization bytime and name. Up to three subdirectories can be selected below the Main directorywith the last box defining the final filename in the last sub-directory. All four levels neednot be used. Clicking the drop down list box in the far right of each selection box gives achoice of various time and filename + time options for each directory level. Once aselection is made that includes the filename created above, no lower levels areavailable. In Figure 3-12 a sub-directory named using the year and month will becreated under the DataLinkAQ directory and in it will be files named by including thedate in front of the filename selected.

The Select Date to Test OutPut FileName defaults to show the path to the file that willbe created as of today’s date. Clicking the calendar drop down button in the box wherethe date is displayed allows selection of another date and the example display will showwhat a file would be named on that date.

5 Automatic PollingOne of the major benefits of DataLink/AQM is automatically downloading data from adata logger at specified times and intervals.

5.1 Activate Automatic PollingDataLink/AQM may be set up to automatically poll stations in either or both of twosequences, daily and on a chosen time interval. To achieve this there are two groups ofstations to be polled in the left window of the main DataLink/AQM screen. The first, theRetrieveQueueGroup, includes the stations to be automatically polled once a day. Theother, the Rept.RetrieveQueueGroup, includes stations to be polled on any repetitivetime interval.

When polling occurs, all data in the data logger that has not been previously downloadedwill be downloaded at that time. The data will also be sent to text files established duringconfiguration (Section 3.3.7.1.3.1, Page 21) if the Enable Text File Output box waschecked.

5.2 Daily PollingAdding stations to the daily polling queue is a simple drag and drop procedure. In theleft panel of the main DataLink/AQM screen, highlight System Group. This displays allof the stations in this group in the right panel. Click the station to be automatically polleddaily, and with the left mouse button depressed, drag and drop the station ontoRetrieveQueueGroup in the left window (Figure 5-1).

7 View Data and/or Manually Print ReportsData is accessed and reports may be selected by clicking the station of interest in theSystems Group in the left panel of the main DataLink/AQM window and then clicking theData Browser icon (Item 1, Figure 2-1, Page 8). The Data Browser Screen will appearwhich details the station’s data base (Figure 6-3, Page 44).

DataLink/AQM provides a variety of printable reports, flexible in both set up andexecution. The following reports are available:• Annual Report – A report of monthly averages and totals for a selected year.• Monthly Report – A report of daily averages and totals for each day of a month.• Daily Summary – An hourly average report for a selected date(s).• Aux Report – A report of data averaged over a selected time period.• Monthly Detail – Reports hourly averages, for a single channel, for each hour in a

month.• Channels Output Report – A monthly report of hourly averaged data for several

channels.• Alarm Report – A report of incidents or channel values exceeding those

programmed into the data logger.• Filtered Alarm Status Report – A report of selected incidents or channel values

exceeding those programmed into the data logger.• Calibration Report – A report of calibration times with actual and expected values.• Edited Report – A report that compares modified data values with actual values.

7.1 Channel Definition TableThe Channel Definition Table displays all of the channels available at the data logger.

Click the Channels button in the Data Browser screen (Figure 6-3, Page 44). Apassword box appears similar to Figure 3-4, Page 11. If a password has been set, enterit and then click Ok. Otherwise, simply click Ok. A password can be added or changedby clicking the Change button before clicking Ok (Section 3.2.2, Page 11).

When OK is clicked, the Channel Definition Table appears (Error! Reference sourcenot found.). This table defines the channels based on the data downloaded from thedata logger during configuration of DataLink/AQM.

The screen includes two different tabs at the top. The first, Data Channels, reflects rawdata definitions. The columns at the top list the Channel number, data Name, an Alias(or alternate name), the last valid date, the unit of measure, the number of decimalpoints in the data, the number of decimal points in the calibration data, the type of unit(Scalar, Vector, or Deviation), flags (yes or no), visible (yes or no), the input location,offset value, a multiplier, the maximum and minimum values for graphics, a High Highlimit, a High limit, an hourly average value limit, a daily average value limit, a monthlyaverage value limit, the expected zero calibration limit, and the expected span drift ofcalibration values.

Figure 7-1 Channel Definition Screen

Click the Calculated Channels tab to see the channels of calculated data and anyrelated channel definitions available at this station.

The channel editor at the bottom of the screen (when on either tab) allows the updatingand editing of values on any given channel. It consists of left and right arrows forselection of channels, plus and minus buttons for adding or deleting channels, an uparrow for allowing editing of a channel, a check for accepting an edit, an “x” for cancelingan edit and a circular arrow for restoring the previous data definition. It is stronglyrecommended that these functions not be used, since it increases the risk that the datalogger and DataLink/AQM are not synchronized. It is always better to update data linkby downloading the channel data from the data logger (Section 4.3, Page 35)

Close the Channel Definition Table by clicking the “X” in the upper right hand corner ofthe window. The Main Data Browser Screen returns.

7.2 Report DateIn the date box to the right of the Channels button on the Data Browser screen (Figure6-3, Page 44) select the date of the data to be viewed, edited, or on which a report willbe based. Click in the date box and change the month, day and/or year by either typingthe date or using the up and down arrows. Alternately, click the drop down arrow at theright side of the box and a calendar appears. Use the forward/reverse arrows to select amonth and then click a date.

7.3 View Channel DataThe available channels are listed as tabs at the bottom of the screen. Select the data tobe viewed or modified by clicking the appropriate tab. Note the upper right hand cornerof the screen displays the unit of measure and its type for easy reference.

The data is divided into two panels. The left panel shows the daily average data, whilethe right panel defaults to display interim (auxiliary) data values for the date selected.Clicking the drop down arrow in the right panel’s title box, offers other data viewsincluding daily and hourly reporting, an Alarm report, an Alarm look up table (or Alarmcode definition) report, a Calibration Report and an Operator Memo report.

7.4 Modify DataOn occasion it may be necessary to modify data to reflect events that may have causedthe data logger to log inaccurate or suspect data. Either Auxiliary (preliminary or interimdepending on the chosen configuration in Section 3.3.7.2, Page 27) or Hourly data maybe modified. Also, all fields in the Calibration, Memo and Alarm Look Up Tablereports may be modified. No fields in the Alarm report may be modified.

From the main DataLink/AQM window click the station for which the report is desired.Then click the Data Browser icon (Item 1, Figure 2-1, Page 8). To modify data, use thedrop down arrow in the right data panel’s title box and select the type of data to bemodified. The appropriate data will be displayed in the data panel. Next, click the date ofdata to be modified in the left panel. The left arrow with a line on its left just above thewindow will move you to the first record of data. The right arrow with the line on its rightwill move you to the last available record. The up and down arrows on the keyboardmoves the selection among available dates in the left panel or data elements in the rightpanel. Alternately simply click in the box of the data to be modified in the right panel. Inthe “Modified” column type the value to be used. In the “Flag” column, type the desiredflag if any. Only these two fields in the right panel may be updated. To delete a recordcompletely, use the “-“ button above the panel in question. An entire date can bedeleted if it is selected in the left panel. Use caution!

While Daily data appears to allow direct modification, it may only be modified to theextent that daily values are recalculated to a new modified value based on modifiedHourly data. When Hourly data is modified, it is necessary to update the Daily reportdata. To do so, after completing modifications, click the Recalculate Daily Averageicon to the left of the title box in the left panel. This will recalculate the Daily report andplace the result in the “modified” column.

Modified data does not change original data values; it simply updates a second set of“modified” data. Therefore, reports offer a choice of “Actual” or “Modified” data. Reportsusing modified data use actual data for any time point for which data was not modified.A “Modified” report would be identical to an “Actual” report if no data was modified.

To report modified data, click the Modified radio button in the Data Source block to theright of the Print Width box below the Selected Channels data window. This selectionMUST be made before printing any modified data report since the data source is NOTsaved with any report template.

7.5 Reports Available

7.5.1 Annual Report (Figure 7-2)From the main DataLink/AQM window click the station for which the report is desired.Then click the Data Browser icon (Item 1, Figure 2-1, Page 8). The Data Browser

51

screen appears (Figure 6-3, Page 44). On a menu bar directly below the Channelsbutton at the top left and above the data panels, the available reports are listedhorizontally. Beginning from the left, the first report is an Annual report.

The Annual report produces an annual summary of selected channels, reporting theyear to date average of data based on monthly averages. If data does not exist for theentire year, select your reporting dates carefully as the annual report will use a zero (0)average for months prior to initial data collection, and will use the year to date averagefor the last month there is data available in subsequent months without data. Also, thereport will average only the months included in Separated Reports date boxes.Therefore, in the year a station is first established, use the first day of the first full monthof data available as the report date. The report will consider this the first month of theyear and will average over the months that are included up to the To date. Maximumand minimum values will indicate the month of the year the data was in, using 1 torepresent the first month of data in the From date. In other words if the From date is inMay, the report will consider May the first month of the year. If a maximum value occursin May it will be reported as month 1.

Click the Annual button and configure the report using the guidelines in Sections 6.4.1through 6.4.7, Page 45. Remember to give the report a name, the template a name (nospaces; all CAPs), and to SAVE the report. The template name need not be an“AUTOREPT” template name. Any descriptive name is proper. The report will then beavailable by clicking the drop down arrow in the Select Existing Template Name: boxat the top of the report screen.

To change to a bar chart or area chart, click the Line button on the function bar just tothe left of the PointerOn/OFF function. The chart becomes a bar chart. Click the Barbutton and the chart rotates to an area chart. Click the Area button and the chart returnsto the line chart.

8.1.2 Alter Chart AppearanceTo make Trend Charts easier to read, many additional chart formatting features areavailable. Each channel can be independently represented by various types of lines,bars, or areas.

Access alternate formatting by clicking the ChartEditor button located at the top right ofthe screen (Figure 8-2). A Chart Parameters Inspector window appears on the rightside of the screen (Figure 8-3).

The station and channel selected is shown in the Channel Properties section of thewindow. The window will default to the last channel selected in the Stations/Channelssection.

Note that each of the parameters on the chart is drawn at a different depth on thescreen. Therefore, it is possible for “Area” channels to “hide” data from anotherparameter drawn deeper on the screen. To allow moving parameters to different depths,a Chart Position function is provided directly below the channel identification box.Clicking the arrows brings the selected channel forward or backward on the chart. Bymoving an area or bar channel further back, “hidden” data can appear in front of otherareas or bars.

The next section is the Chart Properties section of the window. By clicking the dropdown arrows to the right of each box, alternate choices are provided for colors (16),chart type (3), line style used to draw lines and bars (5), line size or thickness (virtuallyunlimited), and area types (7).

The next section is the Mark Value section. Clicking the check box will provide a boxwith the data point value for each data point available for the selected channel.

8.1.3 Print and Save Charts and Chart ConfigurationsA chart may be printed by simply clicking the Print button on the function bar betweenthe Stations/Channels section and the chart display. However, a Printer Property tabis provided for selecting printers and adjusting margins, orientation, and resolution of thebit map image.

Any chart may be saved in a location of choice simply by clicking the To File button onthe same function bar.

Finally, when closing out of the Trend Chart function (by clicking the “X” in the upperright hand corner of the window) an option is given to “Save Trend Chart Config?” If yesis selected, the configuration will be automatically recalled the next time the Trend Charticon is selected while on SystemGroup in the main DataLink/AQM screen.

8.1.4 Automatic Chart UpdateThere is a button next to the ChartEditor button that provides for automatically updatingthe trend chart whenever new data is available (Figure 8-1). To engage this feature,simply click the button. The button will recess indicating auto update is on. To turn thefeature off, click the button again.

8.2 Single Station/Multi Channel Trend ChartsOn the main DataLink/AQM screen, select the station to be charted. Click the TrendChart Icon (Item 2, Figure 2-1, Page 8). The single station Trend Chart screen appearswith the name and address of the station in the title box. The screen looks very muchlike the Trend Chart (Multi Station). The only difference is that there are no boxes forselecting a station.

Proceed to format the chart as in section 8.1 through 8.1.4.

9 Wind RoseDuring station configuration, in Section 3.3.6, the Wind Speed and Wind Directionchannels to be presented in a Wind Rose were identified. To review or change thisinformation, highlight the abbreviated Station Name of the data logger in the left windowof the main DataLink/AQM screen (Figure 3-2, Page 9). On the menu bar at the top ofthe screen, select Station and then ModifyStation. Enter a password, if necessary,and then click Ok. Click the Wind Rose tab on the Station Configuration screen (Fig.x.x).

The channel identifiers must be exactly the name reported in station configuration. Enterwind speed class boundaries and exit by clicking the top right “X”.

To view the Wind Rose Plot, highlight the abbreviated Station Name of the data logger inthe left window of the main DataLink/AQM screen. Click the Wind Rose icon (item 3,Figure 2-1, Page8). The Wind Rose Plot is displayed (Fig. x.x).

The colors on the plot describe the wind speed as coded at the bottom of the plot. Thewind direction is divided into 16 segments. The length of the wind direction pies or barsindicates the percentage of time the wind blew in a particular direction.

9.1 Wind Rose Plot SetupThe default Wind Rose Plot is for one day’s data on the last date data is available fromthe station. The left window of the plot window allows modification of the data shown inthe plot. The plot defaults to the Date tab for easy updating. However, the first time aWind Rose Plot is selected no data is displayed. This is because setup is not complete.

Click the SetUp tab at the bottom of the date information. The set up tab appears (seeFig. x.x). In the Wind Direction box, click the drop down arrow at the right end of thebox. A list of all available channels is shown. Highlight the proper wind directionchannel and click. In the Wind Speed box, click the drop down arrow at the right end ofthe box. Highlight the proper wind speed channel and click.

The Data Type section of the tab defaults to Aux(Interim). If Hourly or Dailyaverages are desired, click the radio button to the left of the data type desired.

The Data Source defaults to Actual. If Modified data is desired, click the radio buttonto its left.

Finally, the Graphics Type can be changed. The default is a pie slice for each of thesixteen directions which fans out as the percentage of wind from a given direction getslarger. A single width bar may be selected instead by clicking the radio button to the leftof Bar

9.2 Wind Rose Plot UpdateClick the Date tab. In the Start Date box, select the date to begin the plot by eithertyping in the month, day, and year to begin the report in the date box or clicking the dropdown arrow on the right side of the box and then clicking the appropriate date in the drop

67

down calendar. The left and right arrows on the top of the drop down calendar will moveforward and backward among months.

If more than one day’s data is to be viewed, change the number of days in the Count ofDays box by either typing in the number or using the up and down arrows at the rightend of the box.

If specific times are to be viewed, click the check mark in the Use Days Counter checkbox.

Once the date(s) have been selected, click the Go button below the Date section of theleft window to redraw the plot. The Go button becomes activated as soon as anything ischanged. To assure viewing the proper plot, check the parameters entered and click theGo button whenever it is activated.

The Percentage box allows for the outer boundary of the plot to be changed. Thedefault is 60%. However, if data is widely dispersed around the plot, this may be toolarge a percentage making estimating difficult. Conversely, if many of the winds camefrom a single direction, the pie extends beyond the boundary and a reading of thepercentage would be difficult. To change the boundary to view a more easily read chart,type a percentage in this box or use the up or down arrows at the right of the box tochange the percentage. Select a percentage slightly larger than the largest value onthe initial plot. Then click the Go button below the Date section of the left window toredraw the plot.

Buttons are provided to Print the plot, select the printer and set it up (Printer SetUp),and to save the plot To a File.

The colors used for the plot can be changed by right clicking the color to be changedand selecting Color. Clicking the color of choice on the color pallet that appears andclicking Ok will change the color.

Custom colors can be created by clicking Define Custom Colors >>. A rainbowappears to the right of the color pallet. To create a custom color, point to the color ofchoice by holding the left mouse button down to move the pointer around on the rainbowuntil the desired color appears in the Color|Solid block below the rainbow. Then clickthe Add to Custom Colors button. The color selected will be added to the CustomColors: pallet below the main color pallet. Then click the color and click Ok to changeto the custom color. Finally, click the Go button to redraw the plot with the new colors.

When the Wind Rose Plot window is closed by clicking the red X in the upper right handcorner, a Confirm box appears and asks if you wish to save this wind rose configuration.Clicking Yes will replace the last saved template with the wind rose configurationcurrently on screen. Clicking No will retain the previous wind rose template (the defaulttemplate if no other template has been previously saved).

10 Back-Up and RecoveryWhen the database file mode is set to Monthly Based (Separated Dbs) duringconfiguration (Section 3.3.7.1.2), data is kept in separate monthly files with only thecurrent file being updated regularly. Therefore the risk to database corruption andprocessing delays because of voluminous files is limited.

However, if Continuous (all in 1 Dbs) is the configured database, a single file containsall historical data and is continuously being updated. Therefore, as a precaution it iswise to periodically back-up the files. A back-up and recovery routine is provided inDataLink/AQM when in continuous database mode.

Figure 10-1 Password of BackUp Pop Up Box

Select the station that is to be backed up from or recovered to in the left panel of themain DataLink/AQM screen. Click the Back Up Data icon (Item 4, Figure 2-1, Page 8).A Password for BackUp pop up window appears (Figure 10-1Figure 2-1). Enter apassword, if necessary, and then click Ok. To add or change a password, use the sameprocedure as described in Section 3.2.2. The Data BackUp screen appears.

The left side of the screen indicates the data elements that may be backed up. Optionsinclude non date related data which need only be backed up when configurations to theoverall System or a particular Station occur. The date related data include the Daily,Hourly and Aux (Interim) Average Data and the Calibration and Alarm records. Simplyclick the check boxes of the data elements to be backed up.

The right side of the screen allows for either back-up (top half) or recovery (bottom half)..

In the Back Up Data section, select the beginning date of the back-up by either typingthe month, date, and year in the From: box or using the drop down calendar by clickingthe drop down arrow at the right of the box. Next select the last day to back-up using thesame method in the TO: box. Since backup is only allowed while in “Continuous File”mode, the dates may span over month ends. If the Remove after BackUp check box is

selected, the data will be removed from the active database and the active database willbe reduced in size improving program performance time. If an existing backup file isbeing used as the destination, selecting the OverWrite Existing Records check box willoverwrite similar data in the destination file meaning all previous data in the file will belost.

Figure 10-2 Data BackUp Screen

The Destination section of the screen allows the selection of where the backup file willbe created. If System files are being backed up, enter a directory path and the name ofthe file to be created in the System Area box. Alternately, click the browser button onthe right side of the box to select an existing location anywhere on the computer’snetwork. Use the same technique to select a destination for station data elements in theStation Area box. It is a good idea to use a date in the destination filename (e.g.CalibratonRecordBackup20031031), thereby creating separate files for each backup.

When selection of data elements, dates, check box options and destination locationshave been completed, simply click on the BackUp icon. The backup files designatedwill be created where desired.

The lower right quarter of the Data BackUp screen provides for recovering data bymerging data from an exiting back-up file into the active data file. In the Merge Data Insection select the beginning date of data to be returned to active status by either typingthe month, date, and year in the From: box or using the drop down calendar by clicking

Title Box includes both Shortand Long Station NamesNon Date related data:

11 Real Time Data AcquisitionThe Real time version of DataLink/AQM (DataLink AQM-RT) has a separate module tocontinuously update and display data . Highlight the station of choice in the MainDataLink/AQM screen. Click the Real Time Mode icon (Item 7, Figure 2-1, Page 8) toconnect to the station in “real time” mode. A green Logger Terminal screen appearsand after modem negotiation the words "CPP3794 Connected!” followed by a dataupdate (see Fig. x.x). A new set of data will appear based on the frequency rate setduring initial station configuration (Section 3.3.4 page 15). This rate can be adjusted,until the real time session is closed, by changing the rate of update in the Update Ratebox in the lower left of the screen. To permanently change the update rate, change thestation configuration (Section 3.3.4 page 15)

While in Real Time Mode DataLink/AQM will suspend Real Time Mode to retrieve finaland interim data to the main data base, as scheduled, and then return to Real TimeMode.

When in Real Time Mode a separate data base is created, using instantaneousinstrument readings collected by the data logger. If the update rate is every 10 seconds,the data base will contain instantaneous data with six updates per minute. The data canbe displayed in meter form, showing the latest “snapshot” readings, on a Real TimeTrend Chart over a selected number of data points, or in tabular form.

11.1 Meter SetupOn the main DataLink/AQM screen, select the station to be charted. Click the DisplayRealTime Meters icon (Item 8, Figure 2-1, Page 8). The RealTime Meters Display willappear (Fig. x.x ). There are two types of meters to display data; gauges and “LED”bars.

11.1.1 Gauge ConfigurationThe top left gauge is reserved for Wind Direction. Double click the gauge space andyou will get a depiction of a Wind Direction gauge (Fig. x.x).

Double click the Wind Direction gage. A WindDir window appears for set up (Fig. x.x).In the Channel Properties section, click the drop down arrow at the left of theChannelName box and then click the proper wind direction channel. The DisplayProperties section allows changing the meter’s default values. The MeterOuterColorbox allows selection of the gauge’s face color. The MeterScaleColor box allowsselecting the color of the color of the letters and dots on the meter’s face. TheMeterPinColor box allows selecting the color of the needle hand that indicates the winddirection. In addition to the gauge, the latest value is shown in a box in the center of thegauge.

Click and hold the button down on the slide to the right side of the window and pull itdown to show the remaining setup parameters. The MeterValueDec box is used toselect the number of decimal places to show in the “value” display box at the center ofthe gauge. The MeterValueDigit box determines the number of digits wide the “value”

72

display box is, including decimals. To change the font, click the Font button in theMeterFont section and then select the font type and other display characteristics of thefont.

Configuration of the other gauges is similar, but with more options. Double click theMeter 1 gauge space and a generic gauge appears. Double click the generic gauge andthe Meter 1 setup window appears. In the Channel Properties section, click the dropdown arrow at the left of the ChannelName box and then click the desired channel. Inthe Display Properties box, select the main color for the meter’s face by clicking theMeterOuterColor box’s drop down arrow and then clicking the color desired (default isblack). The center of the meter can be of a different color. Select the color of the centercircle by clicking the drop down arrow in the MeterInnerColor box and selecting thedesired color (default is green). An area of the display can be programmed to show asection of the face in an “alarm” color for readings greater than an alarm value. Choosethe alarm color from the MeterAlarmColor box (default is red). Next select the color ofthe numbers and dots used to delineate the scale on the meter (default is yellow). Thefinal color to be selected is the color of the needle used to show the last reading. Usethe MeterPinColor box to select its color (default is white).

The values to be shown are next to be configured. In the MeterMinValue box type theminimum expected value to be displayed. It may be a positive or negative value. In theMeterAlarmValue box type the value at which the alarm color will start on the gauge. Inthe MeterMaxValue box type the expected maximum value to be observed.

Click and hold the left mouse button down on the slide to the right side of the windowand pull it down to show the remaining setup parameters. The MeterDisplayAngle boxdetermines how many degrees of the circle will be used for the scale of the data. Typethe desired value or use the arrows on the right side of the box to increase or decreasethe value (default is 260 degrees). In the MeterValueGap box type the increments ofvalues to be displayed (default is 10). The MeterValueDec box is used to select thenumber of decimal places to show on both the scale and the “value” display box at thebottom center of the gauge. The MeterValueDigit box determines the number of digitswide the “value” display box is, including decimals.

The MeterDotType allows connecting the dots between meter readings with a circle byclicking the Dot and Circle check box. To change the font, click the Font button in theMeterFont section and then select the font type and other display characteristics of thefont for this meter.

The remaining gauges, desired for “real time” readings, are configured as Meter1.

11.1.2 LED Display SetupChannels may also be displayed using 6 “LED” bar indicators located below the roundGauges. Double click the empty bar below Meter1 and Meter 3. An empty bar isdisplayed. Double click on the bar, and the GaugeA setup window appears (Fig. x.x).The LED bars show three different spaces: a safe or green zone, a caution or yellowzone, and a danger or red zone. Select the channel (parameter) to be monitored andset the color and values for these zones in a manner similar to those used in section10.1.1 (Fig x.x). Setup other LED meters in the same manner as desired.

73

Fig. x.x is an example of a fully configured display panel.

11.2 Real Time Trend ChartsParameters (channels) of data can be displayed on a “real time” trend chart, updated atthe rate specified during “real time” setup (see Section 3.3.4). Each parameter trendedis individually set up allowing contrasting color assignment.

11.2.1 Initialize Trend ChartsOn the main DataLink/AQM screen, select the station to be charted. Click the TrendChart icon (Item 9, Figure 2-1, Page 8). The Real Time Trend screen appears (Fig.x.x). It is similar to the Single Station/Multi Channel Trend Chart discussed in Section8.2.

Format the chart as discussed in Sections 8.2 and 8.1– 8.1.3 with exceptions asdescribed below.

Since the chart is displaying instantaneous actual data, there is no Automatic Updatebutton. Also, there are no Start Date/Day Count, Data Type or Data Source selectionoptions. Instead there is Total Data Display section with a Count box to allow theselection of the number of data points to show on the “real time” display. In this box,type the number of data points desired or use the up and down arrows to the right of thebox to change the selection from the default.

Real time trend charts may only be line charts, and the pointer option does not exist.Therefore the Line and PointerOn buttons do not exist on the function bar between theTrend Chart itself and the Channels section of the screen. Also, the Chart Editorbutton does provide access to the Chart Parameters Inspector window but, only allowschanges relative to the salient functions of a line chart. It is recommended that the 3Dfunction be employed so that lines of equal value may be seen discretely from oneanother.

Finally, there is the addition of a DataBase tab at the top of the Real Time Trendwindow. Clicking this tab and then the Browse DataBase check box that appears,shows the data that exists in the limited “real time” data base described in Section 11and defined in Section 3.3.4 during DataLink/AQM configuration. This provides theability to view instantaneous data in “real time” mode in tabular form above the RealTime Trend Chart. Use the slide bars at the right and bottom of the table or use theFirst Record, Prior Record, Next Record, Last Record, and Refresh arrows belowthe bottom slide bar to browse through the database.

Finally, to change the amount of data shown, move the mouse arrow to the top border ofthe Trend Chart section until the arrow changes to two horizontal parallel lines with upand down arrows. Depress the left mouse button and slide the border up or down untilthe size of the windows is as desired.

When closing the Real Time Trend window by clicking the “X” in the upper right handcorner of the window, a Confirm pop up box asks “Save RealTime Chart Config?”Clicking the Yes button will save the parameters chosen. However, changes made tothrough the Chart Editor, other than color, will not be saved.
