5.2 Configuration
The EtherCAT nodes are normally addressed via a fixed 16-bit address defined by the EtherCAT master. During
start-up, the master assigns this address to each node, depending on the physical order in the EtherCAT network.
The address is not saved and is lost when the device is switched off.
Fixed-address addressing
With the fixed-address addressing, the slaves are addressed via the station address distributed by the master in
the start-up phase. In the EtherCAT bus topology in the »PLC Designer«, the first slave gets the address 1001,
the second slave the address 1002, etc. The EtherCAT addresses cannot be changed. The EtherCAT address of the
master is 0. Master objects with this address can also be accessed via CoE.
Auto-increment addressing
The auto-increment addressing is based on the bus topology. Each slave can be addressed by means of its physi-
cal position within the fieldbus.
Slave 1 = address 0
Slave 2 = address -1
Slave 3 = address -2 etc.
The master transmits a telegram to the slave address. Each slave increments the address during the telegram cy-
cle. A slave to whom a telegram is addressed recognizes the telegram by means of the address 0.
