Chapter 1 The Soft Power Management
Soft Power Management (SPM) is a technique that allows users to put the CPU module into a low power
mode (therefore decreasing power consumption) while keeping the capacity to restart work as soon as
something happens.
When the CPU-1450 module is powered off with SPM, just a little part of the board remains supplied. This
part monitors the system inputs, looking for wake-up events.
The low power mode can be activated via software or via a power button, whereas can be deactivated by
either the power button or from one of a number of wake-up events (i.e. receiving packets from network line,
or an alarm at a predetermined time).
