14.4.2. Digital Inputs
To configure digital inputs, press the T1 key from the I/O Config
menu shown above. The DI Configuration page is now displayed.
Pressing the T1/T7 keys will scroll through the screens left/right.
Press T7 to scroll to the right to access the polarity settings.
The polarity of all 20 digital inputs is configurable to OPEN or
CLOSE. The polarity is the active state of the input. Example:
DI01P=Open, so an open signal input on digital input results in a
logical value of ON/TRUE for DI1 in the logic of the controller.
DI01P=Close, a closed signal input on digital input 1 results in a
logical value of ON/TRUE in the logic of the controller.
