Import the STT Configuration Files

  • Valid configuration files for each STT11 or STT20 unit are available locally or over the network.
  • The destination fire network is configured, and its associated BACnet driver is started.
  • To speed configuration, make sure the Desigo CC Transaction Mode is set to Simple or the Automatic Switch of Transaction Mode is set to True.
    The automatic switch setting is recommended. Without it, to re-enable the logs, you need to set the Transaction Mode to Logging at the end of the configuration procedure.
  1. In System Browser, select the first STT unit in one of the following locations:
    - Project > Field Networks > [BACnet Network] > [Cerloop] > [STT20]
    - Project > Field Networks > [BACnet Network] > [Cerloop] > [STT11 system] > [STT11 panel]
  1. In the Import tab, click Browse and select the configuration file for this panel.
  • The configuration file is checked for errors and the Analysis Log button becomes available to show the check log.
  • If the configuration file is valid, the configuration file to import displays in the Source Items list.
  1. (Optional) In the Hierarchies Mapping expander, drag-and-drop an additional hierarchical structure (physical and/or logical according to the database contents) from the System Browser position where you want to import.
    ATTENTION: Carefully select and link the node to the correct position, as you cannot change it later. The only way to modify the additional import setting is to delete the destination node and create it again.
  1. In the Source Items list, click to select all files for import, or click to select an individual file.
  • The configuration file is moved to the Items to Import list.
  1. Click Import.
  • The configuration data is available in System Browser.
  • The Import Log button becomes available to show the import log.
  • A backup copy of the imported file is saved in the project folder, in the shared\Imported_Config_Files\[subsystem name]\ subfolder.
    The file is compressed into a ZIP file named after the current date and time. For example, 2021-10-22_13-52-07.zip.
    NOTE: See also the configuration procedure of the backup folder (search for Handling Backup Size of Imported Files).
    You can control the disk space occupancy, and also disable the backup copy altogether.
  1. Repeat the steps above for each STT11 or STT20 unit.
NOTICE
Objects limit in a project

Based on the hardware category of the installation, there is a limit to the number of objects a project can have.
- The system prevents you from performing imports that would exceed this limit.
- The system warns you if an import would approach this limit (90% or more of allowed objects). You can then choose whether to proceed.
- In a single XNET Network, the maximum number of XINC modules supported is 4. If the number is higher, the system warns you that you may experience performance and instability problems.
- In a single XNET Network monitored by the WAN driver, the maximum recommended number of panels is 5; exceeding this number may result in degraded performance. The maximum number of panels supported is 12; beyond that, the configuration is not supported and we recommend that you contact support.

NOTICE
Incorrect Interpretation of Messages

After first import, if the panel configuration is modified, you will need to import the configuration file again to align Desigo CC. Failing to import the latest configuration file may result in an incorrect interpretation of field messages. An Unidentified event is generated in all cases when a message is received with no corresponding data point.
