Appendix A - Working with Object Type 258 - User Guide

Supporting an Object 258 Data Point

MSIB now supports vendor-specific BACnet object type 258. Object type 258 is a BACnet object type used by Siemens to report on the height and angle of blinds. One data point returns two values: one for the height of the blind and one for the angle of the slats.

MSIB discovery will discover the single type 258 point and create two points with _HEIGHT and _ANGLE suffixes.

For example, if the BACnet point name is BLINDS, then two points will be created under the corresponding MSIB node. The two points will have names BLINDS_HEIGHT and BLINDS_ANGLE. Each point is associated with its corresponding value.

The height and angle values will be pushed to destination services such as Navigator as the two separate _HEIGHT and _ANGLE points.
