The IO address defines either a physical address or a virtual address. When a proprietary logical point has a virtual address, it will be mapped to a BACnet value object type. For information about object data extensions, see I/O Extensions.

In WCIS this feature has been enhanced to support building automation devices (DXR2.x, DXP2.x).

The following key attributes of the Desigo PXC.A logical point will determine its corresponding WCIS Object type.

  • IO Address - defines either a physical address or a virtual address
  • Logical Point Type –logical points with a virtual address are mapped to BACnet value object types.
Relationships between Desigo PXC.A proprietary types and BACnet objects.

NOTICE

LPACI counts accumulation only gets written to the change log every 5 minutes. If you update firmware and the restart completes before the next increment is written, the change log will reflect the last written count value, not the last actual increment.
