VirtualDisplay.V20 Contains the value for V20.
6.7 Virtual Display Data Logging Feature
Data displayed in the first two columns of the Virtual
Display may be logged to a common delimiter text
file (.CSV) and may be opened as a spreadsheet in
an editor that recognizes the .CSV format. When
formatting a Virtual Display Screen for use as a data
logger, please observe the following formatting rules.
This will ensure that the data collected is placed in a
useable format within the .CSV file.
• There may not be any spaces within a text
string either on the screen as fixed text or
written to the screen as a string. I.E. “Analog
Input Raw Volts” should be written as
“Analog_Input_Raw_Volts”
• There must be a space between a label and
tween the column one variable and the column 2 label.

its variable. I.E. “Analog_Input_Raw_Volts
65535” where 65535 is the 5 digit unsigned
integer assigned to the label.
• There must also be a space be

• The operator will be able to select the logging rate through the PLM. The speed that ea
can log reliably is different for each application. It is recommended that 1 second be used as the
maximum data storage rate however the user may set the logging speed as fast as 1mS.
Application Simulator
A useful facility for debugging your DVC710 application

application simulator. Using this facility much of your
application code can be debugged prior to actually
installing the controller and the application on the
target machine.

controlled using the different blue icons. These icons
represent switches and analog potentiometers. The
names you specified for I/Os in your application are
displayed for easy reference. When you depress
(click) the push button icon your application running in
the DVC710 will receive a true or false value for the
switch just like it would if a physical switch had been
closed and a voltage input received on the appropriate
pin of the DVC710 connector. The potentiometer icons
the blue circle and moving it right or left or simply typing in the percent of the range you wish the analog input to
read. This simulates physically moving a potentiometer and conveys the appropriate voltage to your application
as a percent of the voltage range you specified when you configured the analog or universal input.
Furthermore, the simulator will cause analog inputs to jitter slightly by +1 or -1 of the analog inputs 0 to 1023
value. This simulates actual analog input jitter you will experience on your machine.
