Cfw701 Bacnet Objects; Analog Input (Ani) Object; Analog Output (Ano) Object; Analog Value (Anv) Object - WEG bacnet CFW701 User Manual

The Object Type values are defined by the BACnet specification, and object instance is defined by the
manufacturer for each object available for communication.
Each object can present one of the following access types:
R Read-only
C Commandable object. Presents a priority arrangement
W Write-only
W/R Writing and reading
The commandable (C) access type presents a 16-level priority arrangement, where priority 1 is the highest and
16 the lowest. If all the priorities are disabled (NULL), the value of the Relinquish Default property is given to the
Present Value property.
