Switch Settings

Unit No. Switch
Use the Unit No. Switch to set the unit number for units as a CPU Special Unit. Set a unique unit num-
ber for each CPU set Special Unit installed in the CPU Rack and Expansion Rack with the unit numbers
in the unit configuration. Turn OFF the Controller before changing the unit number setting.
Setting method: One-digit hexadecimal
Setting range: 0 to F
Note 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 CPU Unit.
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 before changing the unit number setting.
Additional Information
• If the unit number is the same as one set on another CPU Bus Unit connected to the same
CPU Unit, a major fault level controller error "Duplicate Unit Number" will occur and it will not
be possible to start up the CAN network. After correcting the unit number setting, cycle the
power to the Controller.
