The following are some examples.
• If the Slave Unit with node address 02 has 16 inputs and 16 outputs, it is allocated the InDat02
and OutDat02 I/O ports.
• If the Slave Unit with node address 03 has 32 inputs, it is allocated the InDat03 and InDat04 I/O
ports.
In this case, node address 04 cannot be used for inputs.
