Fixed Allocations Section 4-3
Fixed Allocations Area 3
OUT blocks are allocated to slaves from CIO 3600 to CIO 3663 and IN blocks
are allocated to slaves from CIO 3700 to CIO 3763.
The Slave allocation order is fixed in the output (OUT) and IN blocks starting
from address 0. Each address is allocated at least one byte (rightmost).
• More than one word is allocated for each slave (according to it’s node
address) with more than16 I/O points.
• The rightmost byte of the word is allocated to each slave that has less
than 16 I/O points.
Note The table below shows how fixed allocations areas differ between the
C200HW-DM21-V1 DeviceNet Master Unit of the C200H-series, and the
CS1W-DRM21 DeviceNet Unit of the CS/CJ-series and CJ1W-DRM21
DeviceNet Unit of the CJ-series.
