Mounting to a PLC Section 3-3
3-3 Mounting to a PLC
3-3-1 Mounting to a CS-series PLC
EtherNet/IP Units can be mounted to any slot in 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/IP 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 8.
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-EIP21 EtherNet/IP Unit’s maximum current consumption is
410 mA. Be 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.
3-3-2 Mounting to a CJ-series PLC
EtherNet/IP Units can be mounted in a CJ-series CPU Rack or a CJ-series
Expansion CPU Rack. Connect the EtherNet/IP Unit in any of the positions
shown below using the sliders on the top and bottom of the Unit. Up to seven
EtherNet/IP Units can be mounted for a CJ2H-CPU@@-EIP CPU Unit
(enabling up to eight EtherNet/IP ports if you include the built-in EtherNet/IP
port). Up to two EtherNet/IP Units can be mounted for a CJ2M-CPU3@ CPU
Unit.
If EtherNet/IP Units are 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.
