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).

(3), (6) 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.

(9) 81 xx Initialisation The parameters saved last via I1010

are loaded for

all indexes. If no value has been saved yet, the Lenze

setting is loaded.

(12) 82 xx For all communication parameters (index I1FFF

), the

parameters saved last via I1010

are loaded. If no

value has been saved yet, the Lenze setting is loaded.

xx = 00

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.
