Appendix A - The Object Dictionary
The most important part of a device profile is the Object Dictionary description. The Object
Dictionary is essentially a grouping of objects accessible via the network in an ordered pre-
defined fashion. Each object within the dictionary is addressed using a 16-bit index.
The overall layout of the standard Object Dictionary is shown below. This layout closely
conforms with other industrial serial bus system concepts:
Index (hex) Object

0001-001F Static Data Types
0020-003F Complex Data Types
0040-005F Manufacturer Specific Complex Data Types
