Upon execution of this command the CPU will enter a low power sleep mode but it can be woken up by a serial interrupt or an active I/O interrupt. However, this only save power consumed by the CPU but does not save the static power required by other components on the PLC circuit board. 

Note:

1) Command available only to PLC with firmware r67 and above.
2) Do not execute this command with active Ethernet connection as it can trigger the CPU to lock up into undefined interrupt error state. Only application that are not connected to the Ethernet should use this command.
3) This command is ignored by i-TRiLOGI simulator.
