Sigma parallel port dongle or USB dongle upgrade to software license


Sigma version 4.08


It is becoming increasingly harder to purchase computers with parallel ports.

With the increase use of virtual computer operating systems USB ports may not be available either.

∴ A different type of Sigma licensing will be required.


PSS can arrange for an upgrade from your existing parallel port or USB type Sigma dongle to an SBO/EBO software license entitlement for Sigma 4.0.8.

Sites running Sigma 4.07 or older does not support software licensing and would need to be upgraded to Sigma version 4.08.57 or later to include the software option.

Sigma Software license type availabiliy is documented on page 8 in the Sigma 4.08 release note, you can download a copy here.

For engineers using Sigma 4.08:
The StruxureWare Building Operation Evaluation License, available from the Schneider Electric Download Center, will unlock the Sigma 4.08 for testing etc for the period of the Evaluation License (maximum 3 months or until the expiry of the downloaded license).

For customer’s sites using Sigma 4.08:
To reduce the Sigma system downtime, currently PSS operate on a trust basis and provide the software license in advance.
PSS require you to send the old Sigma dongle back to the PSS representative that is assisting you with your license upgrade. This should be completed within 30 days of receiving your software license.
Once you receive the software license entitlement for Sigma. Install the SBO License Server version 1.6 or later. (it is recommended that the latest available version of the SBO License Server compatible with the computer's operating system is used).

Supply the completed spreadsheet and a copy of the category manager's autherising email etc.
PSS will escalate your request for the software license.

Note: If your current Sigma dongle contains Remote Alarm Manager licensing, Remote Alarm Manager does not support the SBO license server option and would require a separate license and must be installed on a seperate computer. The USB dongle can still be used or a TAC license server type can be used instead of the dongle.

To install the software licensing option for Sigma 4.08: -

  • Stop the Sigma server service.
  • Install SBO License Administrator.
  • Add your entitlement to the SBO License Server.
  • Start the Sigma server service.
  • Sigma should now be licensed.
