1. Is there a way in a digital display to easily check the time stamp of the last collected value against a time value so that a recent value is displayed and an older value causes a warning message?

   This can be done by comparing the last time stamp of the value with the current system time within anIIF()function.

2. Is there any way to set the defaults in the email setup pop-up window for alarm components in RTMC Pro? Or is it necessary to enter this information for each alarm?

   Currently, copying and pasting alarms is the best solution.

3. How can a full-screen view be achieved in RTMC Pro?

   InRTMC Pro, there is a workspace option to auto-size in runtime. This fills up the window and sizes the content as needed. This option is very useful when developing projects to be run on more than one display.

4. How can the data in RTMC Pro be displayed in descending order?

   The table component ofRTMC Prohas the option to display the newest data at the top of the table. It can then be set up to save images of that table component or the entire screen (for use in an HTML page), or theRTMC Proproject itself can be run in theRTMC Web Server.

   UsingRTMC Pro Dev, select theNew Data At Toptable option property.

5. Why does a graph in RTMC Pro seem to skip displaying the first data point?

   The report intervals are open-closed. If a three-hour chart with hourly data is shown, whether three or four points are shown depends on the interval. On an open-closed interval, only three points are shown—one for each hour. On a closed-closed interval, there are four points, but the first point actually represents data outside the three-hour interval.RTMC Prowas designed to use open-closed intervals.

6. Using the Report Range component in RTMC Pro, how can data be selected for a report range?

   The report range is selected by using the forward and back arrows.

7. How can the rising or falling of a value be indicated in RTMC Pro by comparing the last value to the one before it?

   TheLast()function can be used to compare the current value of a variable with the last value that was loaded. To have the graphic display in a graph, create two separate traces that use an expression similar to the following:

   alias("ln:cr1000.one_hour.temp_degf", temp); IIF(Last(temp) > temp, temp, NOPLOT)

   This expression produces a point if the value is increasing; otherwise, it produces a NAN value, which is ignored by the plot. Specify a trace with the down arrow symbol and a different comparison to plot decreasing values.

   This is easier if all that needs to be shown is the current state of the value compared to the previous. To do this, use an alarm that specifies up arrows and down arrows for the images associated with the on and off states.

8. Is there a way in RTMC Pro to designate when the graph should begin using data to calculate and display an average?

   Yes. Use theStartRelativeToNewestfunction as a prefix to the averaging expression to specify how far back to go in the data when the project is first started.

9. In RTMC Pro, what does “filemark” in the StartAtRecord(filemark, Rcdnum,OrderCollected) instruction mean?

   AsLoggerNetcollects data from a table, the table record number, which normally increases by one with each record stored, can get reset to zero through various mechanisms, such as the data logger recompiling its program. Because of this, the record number alone is not sufficient to identify a record within the cache table ofLoggerNet.LoggerNetuses the file mark number to keep these discontinuities straight. Each time that a missed event is detected or the record number regresses,LoggerNetincrements the file mark number that it uses to store new records.

   Starting withLoggerNet4.1, this parameter can be specified with a value of&HFFFFFFFF. TheLoggerNetserver interprets this by looking for the starting record number in the latest file mark.

10. Can RTMC Pro be used with an XY plot to display two values against each other on the X and Y axes?

    Yes.
