DALI / DeviceNet Slave
Document code: MN67837_ENG Revision 1.000 Pagina 29 di 40
DEVICENET MAP:
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 DeviceNet map in OUT (data that the DeviceNet 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 SW67837, it is possible to see which are the bytes reserved inside the DeviceNet array for each DALI node.
Below, it is possible to see the generic structure of 8 bytes reserved for each DALI node:
