9 Identification
In the case of EtherCAT
®
devices, a distinction is made be-
tween address assignment and identification.
Addresses are used for direct communication between the
EtherCAT
®
master and the relevant slave. In doing so, the
master assigns each slave a unique 16-bit address.
Identifications are used to uniquely identify a slave in an
EtherCAT
®
network.
Identifications for AXL E EC devices are:
– Device Identification Value
– Configured Second Station Alias
9.1 Configuration via rotary encoding switch
(Device Identification Value)
You can configure the address assignment using the rotary
coding switch.
After modifying the switch position, restart the device, as the
modification to the switch position does not take effect dur-
ing operation.
Figure 8 Rotary encoding switch
The code results from the sum of S1x10 plus S2x1. The
image shows code 77 (7x10+7).
Switch position 01 ... 159
Set the EtherCAT
®
explicit device identification manually
with this switch position.
Reserved/invalid switch position
The device starts with the previous settings, e.g., with the
settings that were valid before the device was restarted.
9.2 Configured Second Station Alias
For information on how to use the “Configured Second Sta-
tion Alias” identification, please consult your configuration
software.
9.3 Hot Connect
The Hot Connect functionality allows preconfigured sections
to be removed from or added to the data traffic before the
start or during operation of the system. This can be carried
out by disconnecting/connecting the communication line or
by switching a device on/off, for example. This is called “flex-
ible topology” or “Hot Connect”.

The device is ready for operation after power-
ing up, as soon as the RDY LED lights up
green.
A connection to the device cannot be estab-
lished in the firmware startup phase.
As soon as the RDY LED lights up green, a
