6.4 Address allocation
The EtherCAT slaves are normally addressed via a fixed 16-bit address defined by the EtherCAT
master. During start-up, the master assigns this address to each slave, depending on the physical
order in the EtherCAT network. The address is not saved and is lost when the device is switched off.
In the »Engineer«, the address assigned is shown under the Settings tab in the Active station
address display field (C13864
/ C14864).
Defining Explicit Device Identification
There are two ways to assign the slave to an identifier (station alias):
A. Via the EtherCAT master with the assignment of the "Configured Station Alias" (from SW
version 04.00 of the communication module).
B. Via the Station alias address input field.
Valid address range: 0 … 32767
• Address '0' means that no station alias is assigned.
• If the value is > ’0’, the address cannot be assigned by the EtherCAT master.
• Impermissible addresses are marked in red in the input field.
• The address is written to code C13899
/ C14899.
Note!
• The station alias must only be set if the EtherCAT slave is part of a "hot connect" group
or
integrated in the modular machine configuration of Lenze.
• The station alias must be unambiguous and must only be assigned once within the
EtherCAT network.
• Use the same station alias in the EtherCAT master and in the slave.
