Example) For explanation, the example shown in Screen 2-2(a) is
used.
On Screen 2-2(a), SLAVE NUMBER is 3. So, addresses
are assigned to the DP-Slave at station number 3.
DI ADDRESS is R0000, and DI SIZE is 32. So, a 32-byte
DI data area is assigned, starting at R0000, to the DP-
Slave at station number 3, as indicated below.
DO ADDRESS is R0100, and DO SIZE is 16. So, a 16-
byte DO data area is assigned, starting at R0100, to the
DP-Slave of station number 3, as indicated below.
DI data area assignment
R0000
DI data from DP-Slave #3
R0032
DO data area assignment
R0100
DO data to DP-Slave #3
R0116
For diagnose data, similarly, DGN ADDRESS is R0200,
and DGN DATA SIZE is 6. So, a 6-byte diagnose data
area is assigned, starting at R0200, to the DP-Slave of
station number 3, as indicated below.
