The allowable date range is from January 1, 1980 to January 18,2038. This limitation is due to Microsoft Visual C++, the development tool that was used to write theprogram code.Detailed information about how ADAMView handles date information is as follows:9(1) Item: Time Stamp BlockThe date format of Time Stamp Block is MON Sep 23 14:43:52 1992. Note that the year is in a fourdigit format.(2) Item: Timer Clock BlockFor Time of Date or Elapsed Time (both cyclic and non-cyclic), the block output is based on theseconds elapsed since midnight (i.e., 00:00:00) January 1, 1970 Universal Coordinated Time.(3) Item: Alarm Log BlockIf the Alarm Message Format: Date (MM/DD/YYYY) option is checked, the date message for the alarmwill be stored in the ADAMView.ELF file in MM/DD/YYYY format, where YYYY represents the year.It is a four-digit year format, and thus Y2K compliant.
This file is used in the Report Designer for a listingreport.(4) Item: Historical Trend BlockThis stores one file per day in binary format and the filename is YYMMDDXX.HST, where YY representsthe year. For example, if it is 1998, then YY = 98. For the year 2001, YY = 01. If your system isrunning from December 31, 1999 to January 1, 2000, ADAMView will store the historical data into twobinary files: one is 99123101.HST and the other is 00000101.HST.You can search back and forth to view the data on December 31, 1999 and January 1. 2000.
It displays the date as month/day/year, where the year is in a four-digit format.In addition, the HIST Conversion under the File menu can accept a four-digit year in the Start Date andEnd Date fields for the conversion range. ADAMView can retrieve the right historical binary file (*.HST)and convert it to an ASCII file (*.TXT).(5) Item: Log File BlockFor the Open method: "Open at n minutes from midnight" under Advanced Option, the file will beopened according to the day which is independent of the year.(6) Item: Runtime Error Message File: RUNERR.LOGThe date format is MM/DD/YY HH:MM:SS. Although the year is stored in two-digit format, this is onlyfor storage purposes.(7) Item: Basic Script CommandsThe date-related commands (i.e., Date and Year) both accept and output 4-digit years.(8) Item: Report DesignerFor the formatted report, i.e., Monthly/Yearly reports, the database filename is MNYYYYMM.DBFwhere YYYY represents the year.
It is in a four-digit format.For the listing report, i.e., Alarm/Control report, it will retrieve the correct data for the report date whichaccepts a four-digit year format.The date-related commands: $DATE outputs four-digit year format like MM-DD-YYYY.101.4.3 Improved Setup/Uninstallation UtilityADAMView 4.25 includes a comprehensive installation and uninstallation utility.
After installingADAMView 4.25, it will create an Advantech Automation /ADAMView folder by default. It contains thefollowing icons: ADAMView Builder, ADAMView Runtime, ADAM Device Manager, Uninstall ADAMView,ADAMView Help and Basic Script Help. If you wan to uninstall ADAMView, you simply click on theUninstall ADAMView icon. ADAMView, including program files, installation folders and Windows registry,will be automaticallyremoved from your computer.
You do not have to worry about deleting files manually.1.4.4 Improved Robustness and ReliabilityProgram robustness and reliability have been improved considerably in this release. ADAMView 4.25provides memory monitoring functions and protection against insufficient hard disk space duringcontinuous operation. In addition, there is also improved protection against improper use and hardwarefailure.(1) Memory Monitoring FunctionsA new tag named "FreeSpace" has been added under "VIRTASK". It is used to monitor the freememory space of the system when running.
To enable this function, the user has to set a value in the\Windows\ADAMView.INI file manually as follows:[System]MemoryCheck = 1After adding this entry to the ADAMView.INI file you should open ADAMView and create a tag block.Configure this tag block by selecting VIRTASK under the Display/Virtual Tag field, and then selectFreeSpace in the Tag Name field.(2) Protect Historical Data Against Insufficient Hard Disk SpaceIn the Historical Trend Display, ADAMView will record the historical data to files by date.
WhenADAMView is run continuously for long periods of time, there is a chance of running out of hard diskspace. To protect against this, ADAMView 4.25 removes the files generated by Historical Trend Displayautomatically. It automatically removes historical files that are older than 30 days by default. Userscan change this period by setting "HistDaysAgo" under the [System] section in the\Windows\ADAMView.INI files as follows:[System]HistDaysAgo = 15This modification will cause ADAMView will remove historical files that are older than 15 days.Note:If you want to keep all historical files, you should set "HistDaysAgo = 0".
ADAMView will notremove any historical files.11In addition, ADAMView 4.25 keeps the runtime from logging the same error messages. This will savespace within the log files and lessen the chance of running out of hard disk space.(3) Protect Software Against Improper Use and/or Hardware FailureTo protect ADAMView runtime from a strategy that is partially or improperly configured, ADAMView 4.25requests the user to configure all icons correctly. Partially configured or improperly configured strategies will not be allowed to run in ADAMView 4.25. In addition, this protects ADAMView from hardwaremalfunction by isolating the input.1.4.5 More EnhancementsADAMView 4.25 provides some new functions, including(1) A New Basic Script CommandCommandQuit(0)DescriptionStops the overall system(2) A New Decimal Formatting Command in Report DesignerThis command is used to specify the number of decimal digits in the Report Designer. The old versionis fixed to 2 decimal digits.
In ADAMView 4.25, it can be configured by the user. The commandsformat is as follows:COMMAND.Nwhere "COMMAND" can be $NOW, $HRnn, $MAX, $MAXT, $MIN, $MINT, or $AVE. "N" represents thenumber of decimal digits which can be from 0 to 9. For example, if a tag's value is 5.123456789, youcan use the follow commands to format the value:Command in format fileResult$NOW(@TASK1#AI1) ms5.12 ms (by default)$NOW(@TASK1#AI1).0 ms5 ms$NOW(@TASK1#AI1).1 ms5.1 ms$NOW(@TASK1#AI1).9 ms5.123456789 ms(3) Network Communication Status in Event Windows and Log FilesFor networking communication status, the connection/disconnection messages will show in the Eventwindow. The will also log into the alarm file (ADAMView.ELF) by enabling the Runtime Preferenceevent log in ADAMView.(4) Save and restore previous valuesThis function is used to save the values of control displays at system stop.
These values will then berestored at the next system start. This function is included in Binary Button Control , ConditionalButton Control, Numeric Control, Knob Control, Slider Control and Log File Block.121.5 Limitations and RestrictionsADAMView 4.25 includes the following information about usage and limitations of the software tohelp users use ADAMView correctly.(1) Basic Script ProgrammingCategoryTaskDescriptionStart/stopa task* To start/stop a task by Script, the task's startingmethod must be Inactive in Task Property*In Basic Script block or Pre/Post-task Script, it cannotstart or stop the task by itself.* The possible task names passed into GetScanTask("task name") command refer to "the tags created byADAMView".TagRetrieve/set valueto or fromDataCenter* To retrieve/set values of tags in the Data Center viaBasic Script.
