DALI / PROFINET
Document code: MN67848_ENG Revision 1.001 Pagina 28 di 42
PROFINET MAPPING:
Internally to the converter, there are two different arrays of bytes. The data inside them are different:
Array in IN: data read from DALI network;
Array in OUT: data written to DALI network.
Structure of the PROFINET map in OUT (data that the PROFINET Master can read)
For each DALI node configured, the converter will reserve 8 bytes. The map is generated dynamically in relation to the number of nodes
defined: using the SW67848, it is possible to see which are the bytes reserved inside the PROFINET array for each DALI node.
Below, it is possible to see the generic structure of 8 bytes reserved for each DALI node:
