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.
