After Power On and the initialization, the slaves are in the Pre-Operational state.
T
he transition (2) is automatic. The system bus master (frequency inverter or PLC/PC)
triggers the transition (3) to Operational state.
The transitions are controlled via NMT telegrams.
The identifier used for the NMT tele
g
rams is "0" and may only be used by the system
bus master for NMT telegrams. The telegram contains two data bytes.
Byte 0 Byte 1
CS (Command Specifier) Node-ID
Identifier = 0
With the statement of the node ID ≠ 0, the NMT command acts on the subscribe
r
selected via the node ID. If node ID = 0, all the subscribers are addressed. If Node-
ID = 0, all nodes are addressed.

Note: A frequency inverter defined as a system bus master only transmits the
command "Start Remote Node” with node ID = 0 (for all subscribers).
Transmission of the command is done after completion of the initialization
phase and the time delay
Boot-Up Delay 904 following it.
