Codesy Example: Sleep Mode

The uControl controller can be placed into a low power sleep mode programmatically by enabling enterSleep by setting its value to True. The Sleep Mode Input (pin J1B-6. or pin E7 on MC2) which is the system variable SleepAllowed will then have the function of putting the unit into sleep mode. By default this is disabled.

When the digital input Sleep Mode (SleepAllowed variable) is in a low state or 0Vdc (open) the controller will enter a low power sleep state. When the input returns to a high state (batt+)  the controller will come out of sleep mode and resume normal operations. When the controller comes out of sleep mode  enterSleep will be returned to its default value of False.

To disable sleep mode simply set system variable enterSleep to False which is the default setting. When disabled, the sleep mode digital input will be ignored and have no effect although you will still be able to monitor its state.
