I/O Buffer Addresses And Object Dictionary Indices Relation - HMS Anybus X-gateway CANopen Series User Manual

7.3.3 I/O Buffer Addresses and Object Dictionary Indices Relation

The application data bytes 2 - 512 are mapped to three different areas in the Local Object Dictionary.
The same data is mapped to each area, but in different data types. For example: byte to index 2000h, to
2010h, sub-index 1 - 128 and double-word (long) to index 2020h, sub-index 1 - 128. Data from CAN-
open to the application are handled similarly, but with indices starting at 2100h.

Note 1: The picture shows the Transmit data area. The Receive data area has the same structure, but
with indices for byte objects starting at 2100h
