Attributes

Attributes can be specified for Nodes (BU_), Messages (BO_), and Signals (SG_). While the symbols are somewhat ambiguous, most attributes have 3 key parts:

Syntax

BA_ "<AttributeName>" [BU_|BO_|SG_] [Node|CAN-ID] [SignalName] <AttributeValue>;

BA_: The Attribute. Specifies type, NodeName/CAN-ID/SignalName, and value(s).

• AttributeName must have a corresponding definition to be considered valid (see below)

Definitions

BA_DEF_ [BU_|BO_|SG_] "<AttributeName>" <DataType> [Config];

BA_DEF_: Attribute Definition. Specifies the type (BU_|BO_|SG_), name, data type, and value configuration.

DataType	Description	Config format
INT	integer	<min> <max>
FLOAT	floating point	<min> <max>
STRING	string
ENUM	enumeration	"<Value0>","<Value1>"...

Defaults

BA_DEF_DEF_ "<AttributeName>" ["]<DefaultValue>["];

BA_DEF_DEF_: Attribute Default Definition. Specifies the default value for the attribute if none is given.
