Address allocation
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.
Via the Station alias address input field you can assign a fixed address to the EtherCAT
slave.
Valid address range: 0 … 32767
– Address 0 means that no station alias address is assigned.
– Impermissible addresses are marked in red in the input field.
– The address is written to code
.
In addition, specify the use of the fixed addressing on the master.
The address assigned by the master is displayed under code
.
Via standard device code C00002, execute the "11: Save all parameter sets" device
command to activate the changed station alias address and to save it to the memory
module.
Note!
• The station alias address must only be set if the node is part of a "hot connect"
group.
• The station alias address must be unambiguous and may only be assigned
once within the EtherCAT network.
• Use the same station alias address in the EtherCAT master and in the slave.
