I/O functionality
Device profile number
For CAN-8123/CAN-8223/CAN-8423, the specific function is always in 0. The I/O
function defines what kind of device the CAN-8123/CAN-8223/CAN-8423 is. Bit 16, 17,
18, 19 present the DI, DO, AI, AO respectively. For example, if bit 16 is 1, it means that
the CAN-8123/CAN-8223/CAN-8423 has DI channels. If both bit 16 and 17 are 1, the
CAN-8123/CAN-8223/CAN-8423 will have both DI and DO channels. Bit 23 ~ bit 19 is
always in 0. The general information is 0x191 (0x191=401), it means that the
CAN-8123/CAN-8223/ CAN-8423 complies with the CANopen spec DS401.
2. About the objects with index 0x1001 and 0x1003, please refer to the section 5.3.2.
3. The object with index 0x1005 stores the SYNC COB-ID. In the
CAN-8123/CAN-8223/CAN-8423, this object is used to receive the SYNC COB-ID. The
following table shows the data format of the SYNC.

The CAN-8123/CAN-8223/CAN-8423 doesn’t support the SYNC generation, therefore
29-bit ID, bit 30 and bit 31 are always in 0.
4. The object with index 0x1008, 0x1009 and 0x100A records the CAN-8423 product
