Modbus interface
 Central controller ID setting mode
The central controller ID setting mode changes the central controller ID of the Modbus interface. (central controller
ID at the time of factory shipping is central controller ID 20.)
The central controller ID number indicates the Uh Line address and communication priority for the Uh Line
compatible central control device.
Change the central controller ID in the following cases.
• If using Modbus interface with a central control device not compatible with Uh Line, set the central controller ID
as "old controller."
(1) Transition to central controller ID setting mode
• If setting the Modbus slave address with SW1, make a note of the SW1 value before performing central
controller ID setting operations.
• Turn on bit1 of SW3.
(2) Verification of central controller ID
• If SW1 is set to 0, central controller ID is displayed by LED2 to LED5.
