15.0 CONFIGURATION
15.1 System Conguration
The controller features an advanced view into the
hardware through the System Cong I/O Mapping
tab. There are numerous predened variables
associated with the controller that are accessible via
the application program. This dramatically simplies
programming. All of these variables are pre-mapped
with a relevant name linked with their respective
channel. This name can be changed by the user
if desirable. Each variable also has an associated
address, type, and description all intended to help
the programmer. The System Cong I/O Mapping
is organized into folders of related variables e.g.
the System State folder contains information such
as Supply Voltage, Regulator Voltage, Ignition Pin
Voltage, Sleep Pin Voltage, User LED State, USB
Connected, etc. The other folders consist of System
Information e.g. Firmware Rev, Serial Number, Hour
Meter, etc.; Internal Relay status; Global Fault Status
for both active and historic faults; and a Fault Monitor
for managing faults (see below image).
The above variables can be monitored in the application program to alter controller response. For example, if the
battery voltage falls below a predened limit, or the temperature exceeds a limit, the programmer can choose to
initiate a shutdown. Some variables can also be manipulated in the application control program. For instance, the user
LED can be used to impart additional information to the user and the internal relay current can be monitored, and if it
exceeds a predetermined limit, forced off.
Note: The variable radio button “Always update variables” (located in the lower right corner of the above picture) should be checked. If this is
deselected, only variables used by the IEC application will be updated.
