CX8110 30 Version: 1.4
6.2 DIP switch
The DIP switches (S101) can be used to define the Explicit Device Identification for the EtherCAT slave
interfaces (X101, X102). This enables an CX8110 to be swapped with another CX8110 during operation.
Explicit Device Identification is a value that enables the individual CX8110s to be distinguished.
The value can be set with the DIP switches or in TwinCAT. If the value is to be set with the DIP switches, the
setting requires one-time activation in TwinCAT (see:
Using Explicit Device Identification [
}
43] ). The
CX8110 reads the DIP switch at startup.
The DIP switches have no meaning for the Ethernet interface X001.

DIP switch S101 Meaning
1 to 8 The value for Explicit Device Identification can be set with DIP switches
1 to 8.

10 Reserved
Example
To set the value 67 as Explicit Device Identification with the DIP switches, configure the DIP switches as
follows:
DIP 1 DIP 2 DIP 3 DIP 4 DIP 5 DIP 6 DIP 7 DIP 8
On On Off Off Off Off On Off
The following value then results from the activated DIP switches.
