The Edit Connection window allows you to define an alternative communication channel between the DTM and the device. This is used in the following cases:
oYou want to connect the device with an intermediate IP address, different from the address configured in the project (for example, the default address)
oYour PC is connected to the controller via USB, this communication channel is not suitable for communications between the DTM and the device. You can switch to another protocol to make the configuration (for example with a TSXCUSB485 USB to Modbus SL dongle).
Right-click the device node in the Devices tree and click Edit Connection... to display the Edit Connection window:
