6.2.3 Configuring process data
ƒ The process data configuration is defined during the initialisation phase of the
master (PDO mapping).
ƒ The process data configuration predefined application−specifically in the device
description files and can be adapted by the user if required.
6.2.4 Defining the cycle time
The process data objects (PDO) are transmitted cyclically between the EtherCAT master
and the slaves (controllers). The cycle time is set using the EtherCAT configuration
software.
6.2.5 Address allocation
Usually, the EtherCAT nodes are addressed via a permanent 16−bit address defined by the
EtherCAT master. At the start, this address is assigned to each node by the master
depending on the physical sequence in the EtherCAT network. The address is not saved and
gets lost after the device is switched off.
Additionally there is the possibility of allocating a fixed station alias address
(chapter 6.2.6).
6.2.6 Specifying the station alias
By means of the station alias, a permanent address is assigned to the EtherCAT slave.
ƒ For this, carry out the setting via the 0x58C5 object or code C1850 > 0.
ƒ In addition, specify the use of the fixed addressing on the master.
)
Note!
ƒ The station alias must only be set if the node is a member of a "hot connect"
group.
ƒ The station alias must be non−ambiguous and may only be assigned once in
the EtherCAT network.
ƒ Use the same station alias in the EtherCAT master and the slave.
