NOTICE

notice

Data overload at the building hub

When the building hub is overloaded, it can no longer process any requests.

  1. Never connect the building hub with Desigo CC. If the building hub is connected, all nodes can be reached by Desigo CC, which leads to a traffic overload.
  2. Only connect floor hubs with Desigo CC.

 

  1. The BACnet driver is selected.
  1. Open the BT BACnet Stack Config expander.
  2. In the BT BACnet Stack Gateway Port Table section, click Add and then select BACnet/SC.
    NOTE: You can create a maximum of 30 physical connections. If you need more, contact Technical Support.
  3. In the Port Properties expander, set the Network Number where your management station is connected (typically =1).
  4. Leave the Attached check box selected if you want the router port attached and accessible to other devices on the BACnet network.
  5. Configure the SC Hub Connector:
    Add a Primary URI using the format wss://<IP address or machine name>:<port number>. If you directly copy the URI from ABT Site, the appendix sc-hub must be deleted.
    Note: Third-party vendors must configure the Primary and Failover URIs using third-party tools. Siemens devices use ABT for the URIs, as shown in the following image:
    • (Optional) Add a Failover URI in case the Primary URI cannot communicate.
      NOTE: The Primary and Failover URIs must be different.
    • (Optional) Select the Allow Self Signed Certificates checkbox if you created your own certificate.
    • Click Browse next to the CA Certificate field and select a [ABT_project_name_current_date] certificate from the list.
    • Click Browse next to the Operational Certificate field and select a client certificate server.pfx from the list.
    • In the Password field, enter the password created for the private key.
  6. Click Save .
  7. Repeat all steps for each floor hub.
  1. BACnet Driver and BACnet/SC port are configured in Desigo CC.
