After Power On and the initialization, the slaves are in the Pre-Operational state.
The 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 telegrams is "0" and may only be used by the system
bus master for NMT telegrams. The telegram contains two data bytes.
With the statement of the node ID ≠ 0, the NMT command acts on the subscriber
selected via the node ID. If node ID = 0, all the subscribers are addressed. If Node-
ID = 0, all nodes are addressed.

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 initializa-
tion phase and the time delay
