List of data types

The following shows the basic data types mainly used for BACnet modules and their data ranges.
For data types which are not described in the following table, refer to the BACnet standard with which the BACnet module
complies.
• IEIEJ-P-0003:2000 addendum-a (Institute of Electrical Installation Engineers of Japan)
• IEIEJ-G-0006:2006 addendum-a (Institute of Electrical Installation Engineers of Japan)

• How to calculate an ObjectIdentifier
ObjectIdentifier is a 32-bit unsigned integer.
Among 32 bits, the upper 10 bits are regarded as an object type number and the lower 22 bits are regarded as
an instance number.
(Example) AO-10
Object type number of AnalogOutput: 1
Instance number: 10

The ObjectIdentifier is 40000A in hexadecimal (4194314 in decimal).
