DALI MAP:
Internally to the converter, there are two different arrays of bytes. The data inside them are different:
DALI memory array in IN: data read from DALI network;
DALI memory array in OUT: data written to DALI network.
Structure of the DALI memory array in OUT (DALI
CANopen)
For each DALI node configured, the converter will reserve 8 bytes: using the SW67835, it is possible to map the required bytes into the
CANopen objects.
Below, it is possible to see the generic structure of 8 bytes reserved for each DALI node:
