Indexes 1600 hex to 17FF hex are used for Receive PDO mapping, and indexes 1A00 hex to 1BFF hex
are used for Transmit PDO mapping. Sub-indexes after sub-index 1 provide information about the
application object being mapped.
The following indexes describes the specific objects by Slave Unit types.
•
This object gives the mapping for an application that uses digital output functions.

Indexes
Bit length
MSB LSB
Bits 0 to 7 : Bit length of the mapped object.
(For example, for 32 bits, 20 hex is given.)
Bits 8 to 15 : Sub-index of the mapped object.
Bits 16 to 31 : Index of the mapped object.
