Existing Xworks Plus (XWP) projects with PXC64/128 and PXC00..200 devices can be combined and extended with PXC4-2, PXC5, and PXC7 automation stations. Below, four different scenarios are described for such an extension. These scenarios are examples and have to be adjusted to the project and the customer needs.

  • Scenario A:
    Adding a single new PXC4-2/5/7 automation station and/or primary control unit.
  • Scenario B:
    Adding a new floor or building part with new room automation and a primary control unit.
  • Scenario C:
    Securing existing room automation from unsecure communication, adding a new hub.
  • Scenario D:
    Extending and securing an existing installation (combination of scenario B and C).

Each scenario starts with a high-level topology followed by a summary of the required adaptations in the runtime system as well as in engineering and commisioning.

Scenario A: Adding a single new PXC4-2/5/7 automation station and/or primary device

 

 

Runtime system

Engineering and commissioning

Automation

  • BACnet referencing (mixed BACnet revisions): Additional referencing from/to PXC4-2/5/7 devices.

Primary server in PXC64/128 and PXC00..200:

  • Time manager: Keep PXC64/128 and PXC00..200 configuration. Options are:
    • Keep Desigo CC as time manager (recommended).
    • Configure PXC5/7 as new time master (NTP), provide time to PXC64/128 and PXC00..200 primary server(s) (“manager of primary server manager”) (recommended).
    • Add PXC4-2/5/7 as new recipient (third-party BACnet-browser required).
  • Alarm routing: Keep PXC64/128 and PXC00..200 as is.
  • Global calendar: Keep PXC64/128 and PXC00..200 structure and add PXC4-2/5/7 calendar (use one of the option described on the right side).
  • Device supervision: PXC64/128 and PXC00..200: Primary server or other PXC device does "life check" of backup servers, separate life check on new PXC4-2/5/7 devices.
  • System test necessary.
  • XWP:
  • Network: Update BBMD, BDT, etc.
  • XWP-BOS: Stays as is.
  • ABT Site: Define new PXC4-2/5/7 device, BACnet referencing with PXC64/128 and PXC00..200.

Primary server in PXC64/128 and PXC00..200:

  • Time manager:
    • XWP: No upload/RTE online recipient list lost (not recommended).
    • Engineer time manager (NTP) in ABT Site and add primary server as recipient, no actions required in XWP.
    • Add PXC5/7 as time recipient in Desigo CC.
  • Alarm routing: Setup independent new alarming for PXC4-2/5/7 devices (same [NC] in ABT).
  • Global calendar: Create 1 calendar manager object on a dedicated new PXC4-2/5/7 device and set up primary - subordinate calendar relation: Two options are available:
    • PXC4-2/5/7 calendar manager reads data from primary server calendar(s) and distributes settings to subordinate calendars of PXC4-2/5/7 devices.
    • PXC4-2/5/7 in role of new "manager of primary server calendars" writes to primary server calendars (defined in XWP).
  • Note: New calendar solution in planning.
  • Device supervision: Define PXC5/7 as supervisor (not PXC4-2!) for PXC4-2/5/7 devices.

Room

Installed Desigo room automation is not impacted, still communicates with central functions (grouping) and PXC64/128 and PXC00..200 primary control units (BACnet referencing).

 

Operation and monitoring

  • Offline import for newly added PXC4-2/5/7 devices.
  • Life check: add {PXC4-2/5/7 “supervisory” device} to Desigo CC.
  • Use Desigo CC as calendar manager by adding new calendars from PXC4-2/5/7.
