Unit Operating Mode
Change Function
If the node address is set to 00, the Unit operating mode change function will
start.
This function changes the format for the Unit Setup (in the CPU Bus Unit Sys-
tem Setup Area) when converting to a CS1W-ETN21 or CJ1W-ETN21 Ether-
net Unit from one of the previous models (CS1W-ETN01/11 or CJ1W-ET11).
For details, refer to 2-12 Converting from Previous Models.
2-3 Mounting to a PLC
2-3-1 Mounting to a CS-series PLC
Ethernet Units can be mounted to any slots in either a CS-series CPU Rack or
a CS-series Expansion CPU Rack, but the number of slots to which they can
be mounted depends on the Backplane. Up to four Ethernet Units can be
mounted to a single PLC. If it is mounted in combination with other CPU Bus
Units (e.g., Controller Link Units), the maximum total number of CPU Bus
Units that can be mounted is 16.
Note Tighten PLC Backplane mounting screws to a torque of 0.9 N
⋅m, and the
Unit’s screws to a torque of 0.4 N
⋅m.
Note The CS1W-ETN21 Ethernet Unit’s maximum current consumption is 380 mA.
Make sure that the total current consumption of all the Units connected to the
same CPU Backplane or Expansion Backplane does not exceed the output
capacity of the Power Supply Unit.
2-3-2 Mounting to a CJ-series PLC
Ethernet Units can be connected to either a CJ-series CPU Rack or a CJ-
series Expansion CPU Rack. Connect the Ethernet Unit in any of the posi-
tions shown below using the sliders on the top and bottom of the Unit. Up to
four Ethernet Units can be mounted to a single PLC. If it is mounted in combi-
nation with other CPU Bus Units (e.g., Controller Link Units), the maximum
total number of CPU Bus Units that can be mounted is 16.

Up to four Units can be mounted
to the slots shown in the diagrams
on the left.
3, 5, 8, or 10 slots
Can mount to any position,
with 3, 5, 8, or 10 slots.
2, 3, 5, 8, or 10 slots
(Expansion Backplane not possible with 2-slot CPU Backplane.)
