Section 5. Real-Time Tools

If clock updates and display updates are paused while connected

to a datalogger, the connection may time out and terminate the

connection.

There are three Numeric Display screens and three Graphical Display screens.

Each screen is launched as a separate window that can be moved or resized as

needed. The display screens are not minimized if the Connect Screen is

minimized, but they can be minimized independently.

5.1.7.1 Data Display Limitations

There are limits to the number of Input Locations that can be retrieved for

display from some of the dataloggers. Older mixed-array dataloggers can

transfer 62 input location values at a time. The newer mixed-array dataloggers

can transfer up to 500 input locations. The CR10X-TD family of dataloggers is

limited to a maximum of 500 input locations by packet size and record format.

CR5000, CR1000, CR3000, CR800, and CR9000 dataloggers don’t have

practical limits for the number of Public Variables that can be requested or

displayed.

Both mixed-array and CRBasic dataloggers will transfer only the requested

input locations or public variables. However, CR10X-TD type dataloggers

must transfer the entire input locations record in one packet. Because of packet

size, if more than 500 input locations are used in the datalogger program the

record cannot be collected.

5.1.7.2 Numeric Display Screens

Data values collected from the datalogger can be displayed in numerical format

on the Numeric Displays. Pressing the Num Display button and selecting one

of the numbered displays from the drop-down list will bring up a Numeric

Display screen. Each of the three Numeric Displays is configured separately,

and all three can be active at the same time if desired. The settings and

selected data values for a display are saved when the display, Connect Screen,

or LoggerNet is closed. The display settings for each datalogger are also saved

independently, so a different datalogger will have different settings.

An example of a Numeric Display is shown below. If a Numeric Display is

already active but hidden behind other windows, selecting it from the drop-

down list will bring it to the front.

A mixed-array datalogger’s final storage data must be collected

by LoggerNet before it can be displayed.


When a value declared as a Long is being displayed,

–2147483648 (the most negative long value) is used to indicate

NAN (Not A Number).
