Available object types and properties

Object types used in Aranet PRO BACnet server implementation are (1) Device object type, (2) Analog Input object type or (3) Analog Value object type (depends on the object type selection in “Compatibility options”).

1. The BACnet client system needs manual updates for daylight saving status. It doesn’t automatically update and can’t be adjusted through the Aranet PRO base web GUI, which operates on UTC time for its backend processes.
2. UTC offset must be updated from the BACnet client system as it is not being auto-updated and cannot be set using Aranet PRO base web GUI. BACnet UTC offset is inverse of common practice. If your UTC offset is -5 h of GMT, then BACnet UTC offset is +5 h. BACnet UTC offset is expressed in minutes, therefore convert the common UTC offset from hours to minutes.

Analog input / Analog value (measurement) object properties

Property	Access rights
CoV Increment	Read-Write
Description3	Read-only
Event state	Read-only
Object identifier	Read-only
Object name	Read-Write
Object type	Read-only
Out of service	Read-Write
Present value4	Read-only
Reliability	Read-only
Status flags	Read-only
Units	Read-only
9997 (proprietary) –– Time of last present value update	Read-only
9998 (proprietary) –– Date of last present value update	Read-only

1. Description is a combination of sensor hexadecimal UID, group name, sensor name, measurement type and unit, e.g., [500ACE] roomEnv Contact pulse meter pulses (pulses) where

   • [500ACE] –– hexadecimal UID
   • roomEnv –– group name
   • Contact pulse meter –– sensor name
   • pulses –– measurement type
   • (pulses) –– unit
2. Present value can be changed in case if Out of service value is set to “True”. It applies for both supported object types (AI and AV)
