i4BACnet Licensing


Read this article and follow the described steps in order to enable your i4BACnet License.

Given the fact that i4BACnet is a standalone product, an individual license must be issued for it. However, similar to the installation of the product, an i4BACnet License cannot be obtained without an i4scada License. 


The i4BACnet License is granted for a limited number of objects, that can be used by the i4BACnet Connector, web controls, etc.

Since i4BACnet 1.3.X version, the i4BACnet licensing has been upgraded, to a more relaxed use of the licensed objects.

Therefore, the discovery process will no longer apply licenses to the discovered objects. The objects will only be licensed if that object is used.

For the system to recognize an object as used, the following actions/operations need to be performed:

  • The user subscribes to at least one property of an object.

  • The user performs a CRUD operation:

    • create operation

    • read operation

    • update operation

    • delete operation.


      As the deletion is a special operation, please consider the following aspects:

      • deletion can be performed on both licensed and unlicensed objects;

      • if an object was deleted, the number of licensed objects will remain the same;

      • deletion can not be performed, if the device where the object is used, is no longer online;

      • deletion can not be performed, without a valid i4BACnet license.

The current licensing process is more dynamic and relaxed since it only applies the license for the objects that are in use, per BACnet Service Runtime.


Please note that since version 1.3.X of i4BACnet, when your SLA expires, installation of the i4BACnet products will be possible only for the last purchased license version, or higher.
