Rotary switches
Function
The 3 rotary switches are used to set the EtherCAT "Explicit Device
ID" of the interface in hexadecimal code.
Possible settings:
–
0 = stored EtherCAT address, no "Explicit Device ID" assigned
–
1 … 4094 (1
h
… fff
h
) = permissible address range
–
4095 (0xFFF) = reset to factory setting
If set to 0, the address of the interface is automatically assigned
by the EtherCAT master (autoincrement).
Factory setting: 0
