EtherCAT configuration

Addressing the EtherCAT devices
The EtherCAT devices are normally addressed via a permanent 16-bit address defined by the
master. At the start, this address is assigned automatically to each node by the master,
depending on the physical order in the network. The address is not saved and gets lost when
the device is switched off.
"Explicit Device Identification" via rotary encoder switch or parameter
The "Explicit Device Identification" is required if the device is part of a "Hot Connect" group or
the device is operated within a modular Lenze machine application. Each slave receives an
unambiguous identifier for being identified by the master.
Setting Assignment of the identifier
0x00 Identifier via the parameter
0x01 ... 0xFF Identifier via the rotary encoder switches.
Example: Setting for the value 52
(3 × 16) + (4 × 1) = 52
The value set via the rotary encoder switches is used once when the mains is switched on or
after a network restart with
become valid after the network has been restarted.
As an alternative, a master can also use station alias addresses of the slaves that are config-
ured and unambiguous in the network. For this purpose, a station alias address must be saved
in the EEPROM of the device by setting the corresponding register.
The parameters for addressing the device are described below.

Setting of the identifier unambiguous in the network (Explicit Device
Identification).
This setting is only valid for rotary encoder switch setting 0 (0x00).
