2 Select the Settings button next to the Network Type selected, to display the Network set-
tings window, and select the Driver tab (USB is shown as the example below).
3 Make the necessary selections to facilitate communication between the PC and the CPU to
which the PROFIBUS Master Unit is attached, and press the OK button.
Testing CX-Server setup
After making the settings, press the OK button to close the CX-Server interface. In order to verify
that the communication has been setup correctly, press the Test button in the Device Setup tab of
the DTM Configuration User Interface. This will initiate a command to read the Unit’s profile, i.e. the
name of the Unit and the firmware version.
If the communication has been setup correctly, the response of the command will yield the required
information which will be displayed in the Device Information box in the Description and Firmware
Version fields. If the communication is not setup correctly, the two fields will contain three dashes,
i.e. “---”, and an Error message will be displayed in the Error Log view of CX-ConfiguratorFDT. The
communication settings must be changed to the correct value first. Refer to A-5 CX-Configura-
torFDT Warning and Error Messages for more information on communication and download errors.

the context menu.

through CX-Server will be opened automatically.

load will continue.
