  1. Click Save .

Import the Configuration File for each Panel

  • Valid configuration files for each CC11/CI11, and CK11 unit are available locally or over the network.
  • The destination fire network is configured, and its associated BACnet driver is started.
  1. To speed configuration, set the transaction mode to simple. See Switching the Transaction Mode for CS11.
  1. In System Browser, select Project > Field Networks > [BACnet Network] > [CS11] > [CC11/CI11].
  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 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, select the configuration file and click the single selection button .
  • 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.
  1. Repeat the steps above for each CC11, CI11, and CK11 unit.
  1. When finished, to resume normal operational monitoring, set the transaction mode back to logging. See Switching the Transaction Mode for CS11.

 

NOTE:
If the imported file contains objects with a map number (a numerical reference configured at panel level to point to an external graphic), this number is placed as a suffix in the description text of the corresponding Desigo CC objects. For example, Automatic fire zone 1st floor - Map no. 700.

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.

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.

 

7 – Configure the CS11 Events Clock Synchronization

To avoid inconsistencies in the events time stamp, you want to synchronize the CK11 unit clock with Desigo CC.

  1. In System Browser, select Project > Field Networks > [BACnet Network] > [CS11] > [CK11] > [Device CK11].
  1. Select the BACnet tab.
  1. Open the Timing and Status Info expander.
  1. In the Time sync type drop-down list, select Local Time.
  1. In the UTC offset field, enter the UTC offset in minutes, with opposite sign (for example, if the UTC offset is +1 hour, enter -60).
  1. Click Save .

 

8 – Download the CS11 Configuration to the NK823x
  1. In System Browser, select Project > Field Networks > [BACnet network] > [NK823x].
  1. Select the NK8000 tab.
  1. (Optional) Open the Configuration expander, and configure the file transfer mode to apply to subsequent downloads (the current download applies the mode that is currently set).
    This option is set to Use secure download by default (encrypted data transmission on TCP port 20500). If you have a local and safe connection to NK823x, you may want to deselect the check box and apply a faster FTP passive mode. Proceed as follows:
    a. Deselect the check box. Note the warning message about potential vulnerabilities.
    b. Click Save .
  1. Click Download configuration.
  • A confirmation box displays.
  1. Click OK.
  • The download starts. After a few minutes, the new configuration is active.
    NOTE: Depending on the type of modification, the NK823x may need to restart to complete the procedure.
NOTICE
