14.0 CONFIGURATION
14.1
System Configuration
The display features an advanced view into the
hardware through the System Config I/O Mapping
tab. There are numerous predefined variables
associated with the display that are accessible via
the application program. This dramatically simplifies
programming. All of these variables are premapped
with a relevant name linked with their respective
channel. This name can be changed by the user
if desired. Each variable also has an associated
address, type and description all intended to help
the programmer. The System Config I/O Mapping
is organized into folders of related variables (e.g.
the system state folder contains information such
as supply voltage, ignition pin voltage, etc). The
other folders consist of system information such as
firmware rev, equipment type and backlight control
(see image below).
The above variables can be monitored in the
application program to alter display response.
For example, if the battery voltage falls below
a predefined limit, the programmer can choose
to initiate a warning. Some variables can also be
manipulated in the application control program to
impart additional information to the user.
Note: The variable radio button “Always update variables” should
be checked. If this is deselected, only variables used by the IEC
application will be updated.
The System Configuration has a second tab, the
System Config Configuration, that enables the user
to configure settings for battery voltage sample rate.
Note: That depending on the parameter, double clicking the value
in the appropriate value field will either open a drop down menu
to select, allow direct editing or toggle the variable.
