Initial Setup Section 3-2
Mounting FL-net
Units
• Up to four FL-net Units can be mounted to a single PLC.
• The current consumption of the FL-net Unit is 380 mA maximum for
CS1W-FLN22 and 370 mA maximum for CJ1W-FLN22. (The power sup-
ply to the transceiver is not included; it is supplied by the 24-VDC power
supply connected to the power supply terminals on the Unit.)
Make sure that the total current consumption of all Units mounted to the
CPU Backplane or Expansion Backplane to which the FL-net Unit is
mounted does not exceed the capacity of the Power Supply Unit.

Maximum size: 32 bytes (per Unit)
When the allocation data for remote nodes is stored in the FL-net Unit, the
CPU Unit System Setup size is 32 bytes per Unit regardless of the number of
remote nodes set.
3-2 Initial Setup
Item Procedure References
Set the hardware switch. Set a unique number for the Unit so it can operate as a
CPU Bus Unit. 3-4 Hardware Setup
Mount the Unit to the Back-
plane. Mount the Unit to the Backplane. 3-5 Mounting to the PLC
Connect to the network. Connect the Unit to the network using the transceiver
cable. 3-7 Connecting to the Net-
work
Turn ON the CPU Unit. Turn ON the power supply to the CPU Unit. ---
Create I/O tables. Register the FL-net (Ver. 2.00) Unit in the CPU Unit using
the CX-Programmer. 3-8 Creating an I/O Table
Create routing tables. Always create routing tables for using message communi-
cations when multiple CPU Bus Units are mounted to the
same PLC. 3-9 Creating Routing Tables
System Setup Set the operating parameters for the FL-net (Ver. 2.00) Unit
using the CX-FLnet or FL-net Unit Support Software. SECTION 11 CX-FLnet
Support Software Opera-
tions
Restart the Unit. Restart the Unit (turn ON the power again) so that the data
in the System Setup can be read. ---
