Abstract unlimited type

There are three different options for mapping the abstract BACnet data type to OPC UA.

• The BACnet data type is mapped to one of the concrete OPC UA DataTypes Byte, UInt16, UInt32, UInt64 if a byte length is defined in BACnet.
• The BACnet data type is mapped to the abstract OPC UA data type 0:UInteger if the DataType is used in a Variable definition
• The BACnet data type is mapped to UInt64, UInt32 or a subtype of ByteString if used in Structure DataTypes.

Signed Integer

There are three different options for mapping the abstract BACnet data type to OPC UA.

• The BACnet data type is mapped to one of the concrete OPC UA DataTypes SByte, Int16, Int32, Int64 if a byte length is defined in BACnet.
• The BACnet data type is mapped to the abstract OPC UA data type Integer if the DataType is used in a Variable definition

The BACnet datat type is mapped to Int64, Int32 or a subtype of ByteString if used in Structure DataTypes.
