Wakeup Events
When enabling the Power Management feature, the MOSCAD-M user should configure those
Wakeup events that will wake up the unit from Idle Sleep mode.
The possible Wakeup events are:
• DI Wakeup
When a Change of State occurs in DI1 and/or DI2 and/or DI3, a Wakeup event is
generated.
• Push-Button Wakeup
Pressing the push-button when the unit is in Idle Sleep Mode will cause a Wakeup event.
(The push-button is enabled at all times.) The unit will enter Run mode for at least 30
seconds.
• Communication Port Wakeup
A signal received at one of the unit’s three ports, if designated by the user as a Wakeup
event, will cause the unit to wake up.
Port 1 Wakeup: when data stream is received.
Port 2 Wakeup: when data stream is received.
Port 3 Wakeup: when an indication for an active channel (channel monitor) is received.
• Periodic (Internal) Wakeup
The Real Time Clock (RTC) will cause the unit to wake up every 5 minutes to reset the
watchdog timer.
The user application can request a wakeup after a certain period of time or upon receipt of a
specific Wakeup event. This will then cause the system tasks (and the unit) to wake up and the
unit to return to Run mode.
See the ‘C’ Toolkit for MOSCAD Family RTUs manual (68P02956C75) for details on the
system functions which provide these services to the application.

Configurator User’s Guide (68P02961C55).
