Modbus Address List
Use this function to change the Modbus address of a device. The Conext ComBox
automatically assigns addresses when it is installed, but individual values can be
changed as necessary. The default addresses are assigned per device type.
To change a device Modbus address:
1. In Setup, click Modbus Address List.
The expanded window displays a table of addresses that are already reserved
along with the associated device, its ID and On Line status.
2. To change a device Modbus address:
• Select the Device from the drop-down list.
Its address is displayed in the address box.
If you want to make sure you have selected the correct device:
Click and a physical indicator on the device will flash, light up, or beep
depending on the device.
• Click to make sure you view the latest information.
• Enter the new address for the device in the address box. Do not use an
address that is already reserved.
• Click Submit to save the address change.
Note: To change the initial starting address settings, see “Modbus Address
Enumeration”.
Note: Valid Modbus addresses are listed from 1 to 247. The rest are assigned
special meanings.
