Network state after

Impact on process / parameter data after the state
change
(1) – Initialisation If the mains is switched on, initialisation is
automatically started.
During the initialisation phase, the I/O system is not
involved in the data transfer.
After the initialisation is complete, a boot-up
message with its own identifier is sent to the master
and the node changes automatically to the Pre-
Operational state.
(2) – Pre-Operational In this phase, the master decides in which way the I/
O system partakes in the communication.
From here, the change-over of the states is carried out by the master for the entire network. A target address
contained in the command gives details about the recipient(s).

01 xx Operational Network management telegrams, sync, emergency,
process data (PDO), and parameter data (SDO) are
active.
Optional:
Event-controlled and time-controlled process
data (PDO) are sent once when a state change is
carried out.
(4), (7) 80 xx Pre-Operational Network management telegrams, sync, emergency,
and parameter data (SDO) are active (corresponds to
"Enter Pre-Operational State").
(5), (8) 02 xx Stopped Network management telegrams can only be
received.

are loaded for
all indexes. If no value has been saved yet, the Lenze
setting is loaded.

If this assignment is selected, all connected devices are addressed by the telegram. The states of all devices can be changed
simultaneously.
xx = node ID If a node address is indicated, the state change is only carried out for the device with the respective address.
