The C441U and C441V have both screw mounting feet and a din rail
spring mounting feature.
To mount the adapter to a din rail place the bottom of the device on
the rail first then apply gentle upward force while pushing the device
flat against the din rail.

4.1 Connecting to an Ethernet Network
The Ethernet module provides two Ethernet ports labeled P1 and
P2. The two ports allow the module to be connected in either a star,
linear or ring network. These options are described below.
Star Network Connection
In a star network connection one port of the Ethernet module is
connected to a standard Ethernet switch. The figure below depicts
3Motor Insight modules connected to a PLC over Ethernet using an
external 4 port switch:
Figure 5. Star Network Connection Example
Either P1 or P2 can be used in a star network.

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.
Figure 7. Ring Network Connection Example
It does not matter which port (P1 or P2) is used for each connection
shown in the diagram.

(With

Support)
Two common ring algorithms are:
• Rapid Spanning Tree Protocol (RSTP)
• Device Level Ring (DLR)
While the Motor Insight does NOT directly execute these algorithms,
it has been designed to be included in these two types of rings. The
figure below depicts three Motor Insight units connected in a ring
with a PLC that supports a ring algorithm.

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.
Setting Default Range
Address 1 1 to 247
Baud Rate 19.2K 9600, 19.2K,
57.6K, 115.2K
Stop Bits 1 1 or 2
Parity Even Even or Odd
Mode RTU RTU or ASCH
Figure 8. Serial Modbus Connection
ote:N When the C441U or C441V are used with the C440 overload relay, this
serial port is used to connect to the C440 serial port and is NOT available as a
serial monitoring port.
