The type of connection CUEwire is shown in a Composer's "MyProject Resources: Connection". 

If the device is hardware connected directly to the controller's RS485 CUEwire serial port, RS485ToCUEwire must be inserted between the controller and the device in Composer's Configuration window. 

> ⚠️ Every CUEwire device connected to the RS485ToCUEwire device must have a unique address.

#### How to check address conflict in the configuration: 

For this functionality, you have to use drivers for CUEwire devices with version 4.12 or newer. 

Run the project in the debug mode (simulation or hardware) with checked Display Debug Messages in the CUEunit where RS485toCUEwire is connected 

If there is any conflict it will appear in the CVC Debug Window. For example: “ERROR: two or more CUEwire devices have the same Address 4”.
