PDO Mapping Objects
The following table shows the PDO Mapping
Objects. The principle of PDO mapping is the same
for all PDOs. The PDO Mapping table is the cross
reference between the Object dictionary entries (for
example the data of an digital output byte) and the
data field inside an PDO data field (position in the
data field of a CAN message for PDO transfer).
Subindex 0 determines the valid number of objects
that have been mapped. The CO4011 allows a
maximum of 8 mapped objects for each PDO. For
changing the PDO mapping first subindex 0 must be
set to 0 (mapping is deactivated). Then the objects
can be remapped. When a new object is mapped by
writing a subindex between 1 and 8, the device may
check whether the object specified by index
/subindex exists. If the object does not exist or the
object cannot be mapped, the SDO transfer will be
aborted.
If the special CAN features are enabled (CFG3=0),
the CO4011 allows adding of additional mapping
entries without resetting subindex 0. In this case the
device calculates the number of mapped objects by
itself and modifies subindex 0 respectively.
Subindexes 1 to 8 keep the pointers of the mapped
objects as unsigned 32 values. The value is 0 if there
is no mapped object. The structure for these pointers
is as follows.
MSB
Byte3
Byte2
Mapped index
Mapped Index and Subindex together are the
Pointer to the Object dictionary data to be
mapped at this location.
Length gives the length of the mapped object in
bits.
The following mapping object uses index 1600 as an
example for all mapping objects.
