This section explains how to set the various switches on the FL-net Unit.
The unit number is used to identify individual CPU Bus Units when more than
one CPU Bus Unit is mounted to the same PLC. Use a small screwdriver to
make the setting, taking care not to damage the rotary switch. The unit num-
ber is factory-set to 0.

1. Turn OFF the power supply before setting the unit number.
2. If the unit number is being set for the first time or changed, then an I/O table
must be created for the PLC.
■ Unit Number and CPU Bus Unit Allocations
With CS/CJ-series PLCs, words are automatically allocated in the CIO Area
and the DM Area according to the unit numbers that are set. The FL-net Unit
uses these words for receiving control data from the CPU Unit and for notify-
ing the CPU Unit of FL-net Unit and communications status. The word
addresses in the allocated areas for the CPU Bus Unit are important in creat-
ing the user program for using the FL-net Unit, so be careful to take them into
account when setting the unit number.
The following table shows the areas allocated for the CPU Bus Unit by unit
number. This table only shows the correspondences between unit numbers
and the words allocated for the CPU Bus Unit. For details, refer to SECTION 4
System Setup and Memory Allocations.
