Step 6: Define the User-defined Variable
Define a user-defined variable for the area to which each slave is allocated. By using the user-
defined variable, the user program can access the allocation area of the slave.
Below is an example of a user-defined variable in which fixed allocations area 1 is selected.
Fixed Allocations Area 1
OUT blocks are allocated to slaves from CIO 3200 to CIO 3263 and IN blocks are allocated to slaves
from CIO 3300 to CIO 3363 in the memory used for CJ-series Unit. To access the output (OUT)
block and the input (IN) block from the user program, allocate a user-defined variable to the applica-
ble area.
