MITSUBISHI CONFIGURATION STUDIO
5.5 Discovery over Ethernet
Depending on the currently-enabled driver, the Configuration Studio will automatically discover the
device on the current Ethernet network, regardless of whether or not the card’s network settings are
compatible with the subnet upon which they reside. All connected devices are automatically added to
the Discovered Devices panel. This panel is shown by selecting the Online Devices list heading in the
Project panel. In the Discovered Devices panel, discovered Ethernet devices will be listed under
Ethernet and will display the firmware version in brackets and the current IP address in parentheses to
the right of the device name, similar to Figure 2.
Figure 2: Studio Discovery over Ethernet
In order for the studio to discover devices, certain UDP Ethernet traffic (port 4334) must be allowed in
and out of the computer, and firewall applications (such as Windows Firewall) are often configured to
block such traffic by default. If the studio is unable to discover any devices on the current subnet, be
sure to check the computer’s firewall settings during troubleshooting, and add the studio as a program
exception to the firewall configuration if necessary. It may be necessary to restart your PC before the
new firewall configuration can take effect.
