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:
