Preset GPIO Builder/GPIO Command Assignment
GPIO stands for general-purpose input/output. The GPIO Builder is where you
establish the pin assignments for Control/Status Port A. These pins are used
to provide control via contact closure and status via open collector functions
in the unit. Note that the pins numbered in blue are command pins; the pins
numbered in green are status pins.
1. Click the GPIO Command Assignment button in the Preset Configuration
pane (or the button in the G-Ware toolbar). The Preset GPIO Builder window
appears.
2. Click on the Control/Status A pin(s) for which you wish to set commands.
Select Use in Preset to add the pin setting to the preset.
Note that the Active (Low) Command pane reflects the default command string
for the pin selected.
3. To make changes to the command string, select the desired parameters
from the drop-down menus along the bottom of the window.
When you select a different command in the Command menu, the other pull-
down menus change to reflect changeable parameters. For many commands,
the far-right menu allows you to set the command state to 0, 1, or 2. Zero does
not execute the command; it will simply clear the command’s flag, if it is set.
One executes the command and sets the flag to on. Two executes the
command and resets the flag.
The Command Description and Argument Description panes reflect
command and argument information. You can modify this information in the
panes as desired.
4. Click Apply to apply the changes you have made to the selected pin. Or,
click Clear to reset the window to default parameters.
Click Close to return to the Preset Selection pane.
