Setting Example
The following example shows the allocation when the size (bytes) for OUT
block 1 and IN block 1 is set in the allocation size setup table using the speci-
fied values.
Node address 0: OUT size: 1 byte, IN size: 5 bytes
Node address 1: OUT size: 4 byte, IN size: 3 bytes
Node address 2: OUT size: 1 byte, IN size: 2 bytes

Note 1. The numbers in the OUT 1 and IN 1 blocks represent node addresses.
2. Bytes are allocated in order in the blocks in word units in the order of node
addresses. If the allocated size is 1 byte, the rightmost byte is used, but the
leftmost byte cannot be used.
The I/O areas specified here for the slave OUT 1 area, for slave IN 1 area are
used if the slave function is enabled using the Slave User-set Allocations
Switch (word n+1, bit 11).

I/O allocations for the slaves can be updated by setting this table and turning
ON the Slave User-set Allocations Switch (word n+1, bit 11). The Unit restarts
automatically and starts operating with the scan list enabled.
Note Make sure the CPU Unit is in PROGRAM mode and the Unit has stopped
slave communications before you set these values.
