Desigo supports the following BACnet protocol revisions:

  • Desigo CC: 1.15
  • Desigo room automation stations: 1.15
  • Desigo PX: 1.15
  • Desigo Control Point PXG3.Wxxx-1 and PXMx0: 1.13
  • PXG3 router: 1.13

There are third-party BACnet devices on the market that support higher BACnet protocol revisions.

Key

①

Desigo CC

②

Desigo devices with a lower revision or the same revision as Desigo CC

③

Third-party BACnet devices with a higher revision than Desigo CC

Properties from earlier BACnet protocol revisions can be read by a BACnet device even if the device supports a higher BACnet protocol revision than Desigo CC.

New properties from a BACnet protocol revision higher than Desigo CC cannot be read or changed, because they are not recognized by Desigo CC.

The BACnet client ensures the backwards compatibility. Desigo CC should thus have a BACnet revision that is at least the same as all of its connected BACnet servers.

Usually, BACnet devices of a specific BACnet protocol revision fully support earlier revision functions. However, since this is not true in all cases, we recommend that you verify the compatibility in each case.

For an overview of the BACnet functions supported in Desigo, see BACnet Protocol Implementation Conformance Statement (PICS) (CM110665).

Create and delete BACnet objects

The function can be used on Desigo PXC automation stations. Desigo room automation stations PXC3 are not supported.

Third-party devices can be processed using the same functionality as long as they support creating and deleting BACnet objects. PXM20 operating units do not display dynamic objects.

Backup and restore BACnet devices

With the BACnet backup and restore function you can upload saved program data (application program) from a BACnet device to Desigo CC and restore it to the same or a new BACnet device.

The backup and restore function can only be run if the third-party BACnet devices support it.
