Rockwell Automation
Products with Embedded
Switch Technology
The current Rockwell Automation products that you can use to construct a
DLR or linear network include:
• 1756-EN2TR ControlLogix EtherNet/IP 2-port
module - Allows
ControlLogix controllers, I/O modules and communication modules to
connect to the DLR or linear network.
• 1783 EtherNet/IP taps - Allow devices that do
not support embedded
switch technology to connect to a linear or a DLR network. Each tap
uses a device port on the front of the tap to connect to devices that do
not support the embedded switch technology to connect to linear or
DLR networks. The taps have two network ports to connect to linear or
DLR networks.
The network ports used to connect to linear or DLR networks are
different
for each type of tap. The following table describes the types of
taps used with each tap:
The primary advantages of using fiber-
optic networks is the availability
of increased distances between network nodes and greater noise
immunity on the network.
• 1734-AENTR, POINT I/O 2-port Ethern
et adapter - Allows POINT
I/O modules to connect to the DLR or linear network.
• 1738-AENTR, ArmorPOINT 2-port Ethern
et adapter - Allows
ArmorPOINT I/O modules to connect to the DLR or linear network.
Cat. No. Network Ports Description
1783-ETAP 2 copper Two copper network ports connect the tap
to copper l
inear or DLR networks.
1783-ETAP1F 1 copper
1 fiber
One copper network port connects the tap
to a copper linear or DLR network, and one
fiber
-optic network port connects the tap
to a fiber-optic linear or DLR network.
This tap is commonly used to connect a
copper section with a fiber
-op
tic section of
the same network.
1783-ETAP2F 2 fiber Two fiber-optic network ports connect the
tap to a fiber
-optic
linear or DLR network.
