Objects to be transferred (first_mapped_object ... fourth_mapped_object)
For every object to be contained in the PDO, the drive controller m ust know the
corresponding index, subindex and length. The specified length must be identical to the
length specified in the object dictionary. It i s not possible to map parts of an object.
The mapping information has the following format:
Index Subindex Length
16 bits 8bits 8bits
ƒ Index: Main index of the object to be mapped (hex)
ƒ Subindex: Subindex of the object to be mapped (hex)
ƒ Length: Length of object - 8, 16 or 32 bits (hex)
In order to simplify the mapping, the following procedure is given:
1. The number of the mapped objects is set to 0.
2. The first_mapped_object ... fourth_mapped_object parameters can be written (the
total length of all objects is not relevant at this time).
3. The number of the mapped objects is set to a value between 1 ... 4. The length of all
these objects must not exceed 64 bits.
