Ethernet POWERLINK state machine

In Ethernet POWERLINK, a Controlled Node starts up by a
common initialization process. All the states are valid when the
device is powered and they are sub-states of the
NMT_GS_POWERED superstate.

NMT_GS_INITIALISATION

After system start, the device automatically assumes this state
and network functionality begins. NMT_GS_INITIALISATION and
all its sub-states are only internal states of the device.
In the NMT_GS_RESET_CONFIGURATION sub-state, the node
address of the device is identified and it is determined whether it is
configured as a MN or CN. The REPL-01 is a CN and thus, it
enters the NMT CN state machine in the
NMT_GS_COMMUNICATING super-state.
