Section 4. The PC400 Main Screen
Program variables that are declared as Boolean can also be placed on this
display, for dataloggers that support data types. For these dataloggers, an Add
button is available that, when pressed, lists all of the tables in the datalogger.
When a table is highlighted on the left side of the window, any variables that
are declared as Boolean in the program will be displayed on the right side of
the window.
To return the Ports and Flags display to its original state, press the Defaults
button. This will reset all labels to their original names, update the number of
flags based on the currently running program (for CRX000 dataloggers), and
remove any Boolean values placed on the screen (for CRX000 dataloggers that
support data types).
Different datalogger models have a different number of ports and flags. The
Ports and Flags dialog box will display only those ports and flags available for
the datalogger type. Behaviors for each datalogger type are shown below.
• Mixed array dataloggers have a fixed number of ports and user flags that
are available. The ports and flags dialog box will display only those ports
and flags supported by the datalogger; no additional values can be added.
The Defaults button will reset any user-defined labels that have been typed
in.
• CR1000, CR3000, CR800, CR5000, and CR9000X dataloggers do not
have predefined flags. The first time a program is sent to the datalogger,
PC400 will look for a Public array with the name of Flag in the program.
If a Flag array is found, the declared flags will be added to the Ports and
Flags dialog box. The number of flags that will be added is limited by the
number of cells available on the Ports and Flags display. CR800, CR1000,
and CR3000 dataloggers have ports that can be toggled from this display;
they will be displayed in the first column and the remaining cells will be
available to display flags and other Boolean values in the program. The
CR5000’s and CR9000X’s ports cannot be controlled from this display, so
all cells will be available for Flags and Boolean values. For these five
dataloggers, pressing Defaults will reset all labels to their original names,
update the number of flags based on the currently running program, and
remove any Boolean values placed on the screen.
• CR9000 and CR200 dataloggers do not have ports that can be toggled
from this display. They also do not support the declaration of variables as
Boolean. They also do not have any predefined flags. The Ports and Flags
dialog will display one to three columns, depending upon the number of
flags defined in a Public array with the name of Flag in the program.
Pressing Defaults will reset all labels to their original names and update
the number of flags based on the currently running program.
