Refer to the CJ-series Position Control Units Operation Manual (Cat. No. W487) for details on I/O memory
assignment methods.
If you connect more than one ZW Sensor to an OMRON Position Control Unit, the following addresses in the
memory map are assigned in order for the I/O areas.
Set the node address setting switches on the Sensors to 0 to automatically set up the network. Node
addresses 17 and higher will be automatically set for the remote I/O.
For the Position Control Unit, the areas are set only for node 17 (which has the first area for each of the three
memory areas).
To access data from another node from a ladder program, add the correct offset from the first word of the first
area for node 17 and access the resulting address.
