Switch Settings

This section describes the functions of the rotary hardware switches on the front panel of the EtherCAT
Slave Unit.
Unit Number Switch
The unit number switch sets the unit number of the EtherCAT Slave Unit as a CPU Bus Unit.
Setting method: One-digit hexadecimal
Setting range: 0 to F hex
The unit number is set to 0 at the factory.
You can set any unit number from 0 to F as long as it has not been set on another CPU Bus Unit con-
nected to the same Controller.
Precautions for Safe Use
• Use a small flat-blade screwdriver to turn the rotary switches; be careful not to damage the
switch.
• Always turn OFF the Controller's power supply before setting the unit number.
Additional Information
If the unit number is the same as one set on another CPU Bus Unit connected to the same
Controller, a major fault level controller error "Duplicate Unit Number" will occur. After correcting
the unit number setting, cycle the power to the Controller.
