Linear Network Connection
In a Linear network the number of external switch ports can be
reduce, or the external switch can be eliminated all together. The
figure below depicts three Motor Insight modules connected to a
PLC without any external switch.
Figure 6. Linear Network Connection Example
It does not matter which port (P1 or P2) is used for each connection
shown in the diagram.
Ring Network Connection
Some PLC systems and external switches provide support for ring
network topologies. In these systems a closed ring is formed and
a special algorithm is used to allow communications to continue
even if a cable becomes disconnected or one of the ring devices is
removed.

4.2 Setting the IP Address Mode
Though the Ethernet Module has two Ethernet Ports, it only has one
IP address that is used to target communications to the device. The
dip switch accessible on the top of the module is used to establish
the IP address Mode. The switch settings and the resulting behav-
iors are depicted in the table below.
Table 9. IP Address Switch Settings
Value Mode
Behavior at reset (power cycle or configura-
tion reset button)
0 Restore The operating IP configuration will be set to the
follow values:
IP Address = 192.168.1.254
Net Mask = 255.255.255.0
Gateway = 192.168.1.1
Note: This mode is intended for fast recovery
from an unknown static IP configuration. The switch
Value must be changed to apply a new IP setting
1-253 Static
(HW)
The Value determines the last byte of the IP
address. The rest of the IP configuration will be
equal to the Static NV values set via web pages or
other protocol.
Note: This mode is intended for applications where
fast deployment of devices without web configura-
tion is important.
254 Static
(NV)
The IP configuration will be set to the values stored
in NV memory. The default NV values from the fac-
tory are:
IP Address = 192.168.1.254
Net Mask = 255.255.255.0
Gateway = 192.168.1.1
These can be changed from the web page or by
writes to modbus registers.
255 DHCP The IP configuration is set by an external DHCP
server on the network.
4.3 Connecting to the Modbus Serial Port
The serial port on the Ethernet module supports a Modbus RTU or
ASCII protocol as a slave device (default = RTU). The physical layer
settings for the device have the following default values, and can
be modified through the web page or writing to Modbus registers.
A 4-pin connector is provided to connect the device to the Modbus
network as shown in the figure below. Two of the pins provide an
additional connection point for the 24 Vdc power supply.

When operating with EtherNet/IP, the network status indicator states
are described by the following table.
Table 11. Network Status Indicator: Ether Net/IP
Indicator
State Summary Requirement
Steady Off Not Powered
No IP Address
The device is powered off, or is powered on
but with no IP address configured (Interface
Configuration attribute of the TCP/IP Interface
Object).
Flashing Green No
Connections
An IP address is configured, but no CIP connections
are established, and an Exclusive Owner connection
has not timed out.
Steady Green Connected At least one CIP connection (any transport class)
is established, and an Exclusive Owner connection
(defined in Volume 1, Chapter 3) has not timed out.
Flashing Red Connection
Time-out
An Exclusive Owner connection (defined in Volume
1, Chapter 3) for which this device is the target has
timed out. The network status indicator shall return
to steady green only when all timed out Exclusive
Owner connections are reestablished.
Devices that support a single Exclusive Owner
connection shall transition to steady green when
any subsequent Exclusive Owner connection is
established.
Devices that support multiple Exclusive Owner con-
nections shall retain the O->T connection path infor-
mation when an Exclusive Owner connection times
out. The Network LED shall transition from flashing
red to steady green only when all connections to
the previously timed-out O->T connection points are
reestablished.
Time-out of connections other than Exclusive Owner
connections shall not cause the indicator to flash
red.
The Flashing Red state applies to target connections
only. Originators and CIP Routers shall not enter
this state when an originated or routed CIP connec-
tion times out.
Steady Red Duplicate IP If the device has detected a non-recoverable major
fault, the module status indicator shall be steady
red.
Flashing Green
and Red
Self-test While the device is performing its power up testing,
the module status indicator shall be flashing green
and red.
Note: When a single indicator is used to represent multiple IP address interfaces the
state of any one interface shall be sufficient to modify the indicator state (per the
above behavior in the table):
• Transition to flashing green when any one interface receives an IP address.
• Transition to steady green when a CIP connection is established on any interface
(and Exclusive Owner is not timed out).
• Transition to flashing red when an Exclusive Owner CIP connection times out on any
interface.
• Transition to steady red when any of the interfaces detects an IP address conflict.
When operating with Modbus TCP, the Network Status indicator
states are described below.
