Overview
ENET-710 MODULE
(Supports Hot Swap)
The ENET-710 is a data communications module that bridges Ether net and Serial communication
networks. With the increasing importance of networking for industrial c ontrol/automation, the ENET710 module provides Ethernet-networked computers the ability to perform remote monitoring and
control of serial Modbus compatible industrial devic es in the field as well as access to LC700 PLC
CPU modules and the CD600 Multi-Loop Controller. Up to seven clients c an access the ENET -710
via Ethernet and communicate over one full-duplex RS-232C and four half-duplex RS-485
compatible serial ports to serial field devices. The module can be installed in the LC700
Programmable Logic Controller (PLC) to receive power, or it can be operated in a stand-alone
fashion with an external +24VDC power source. There is also a redundant power supply mode
when using both power sources.
Fully compliant with Modbus/TCP, the ENET-710 implements bridging to the LC700 PLC CPU
module serial ports and other Modbus/RTU compatible devices enabling bi-directional
communication between clients on Ethernet and devices on a serial M odbus network. The module
also functions to offer data communications bet ween Ethernet and the CD600 Multi-Loop Control ler
with the CD600 configuration software.
The ENET-710 supports 10/100 Mbps Ethernet and seri al s peeds of up to 115,2 00 bps. T he modul e
is easily configured over the Ethernet c onnection via a web page using a web bro wser. Access to
the configuration web page is username/pass word protected. T he configuration web page gives the
user the ability to set up the serial ports, serial protocols, d evice addr esses and timeouts, module IP
address, and a configuration username and pass word. All configuration data is stored in non-volatile
memory.

Redundant Power Supply Operation
The ENET-710 supports a redundant power suppl y mode to provide continuous operation should
the +24VDC power source fail. To make use of the redundant power supply mode, install the
module into the LC700 PLC rack and connect a +24VDC source to the module’s +24VD C input as
described in the installation section of this manual. In this c onfig uration, th e modul e will be powered
from the +24VDC source with power from the LC700 PLC rack as the backup. Note that when both
LC700 PLC power and a +24VDC source are present, the +24VDC source will always be the
primary power source.
Available Ports
Ethernet Port
The ENET-710 provides one 8-conductor RJ45 jack for connecting to an Ethernet network via
category 5 or better unshielded twisted pair (UTP) cabling. Built into the jack are two status LEDs.
When an Ethernet link is active, the green LED will light a nd stay illuminated. The orange LED will
flash on and off to indicate transmit and receive data activity.
The ENET-710 supports up to 7 TCP/IP sockets, enabling up to a total of 7 clients or applications to
communicate with the ENET-710 for accessing slave serial devices. Note that accessing the ENET710 configuration web page does not count against the 7-socket limit.
Serial Ports
The ENET-710 has a total of five asynchronous serial ports, P0 – P4. Allowable communication
speeds are 9600bps, 19200bps, 38400bps, 57600bps, and 115,20 0bps. Data size is fixed at 8-bits
with a choice of even, odd, or no parity and 1 or 2 stop bits. When 2 stop bits are selected durin g
port configuration, the parity setting used for the port by the ENET-710 will be no parity, regar dless
of setting. Each serial port also has green LED for Tx and a yellow LED for Rx that indicate data
activity on that port. The top LED in each pair will li ght to indicate rece ption of data while the bottom
LED lights to indicate transmission of data.

Supported Serial Protocols
The ENET-710 supports two serial communication protocols including Modbus/RTU and CD600.
Modbus/RTU and CD600 protocols are avail able on all five serial ports. The protocol is selectable
under the configuration menu for each serial port (see the configuration section later in this manual).
Modbus/TCP Protocol
In Modbus mode, the ENET-710 acts as a bridge between Modbus/TCP and Modbus/RTU. The
ENET-710 takes Modbus/TCP frames received on port 502 from the Ethernet connection and
creates a Modbus serial line protocol data unit b y computing and appending a CRC and inserting
the device address extracted from the Modbus/TCP frame. It then sends the ser ial packet out the
serial port that has been configured with the specified device address. Upon receipt of data from a
Modbus compatible device over a serial port, the ENET-710 verifies th e CRC on the data and, if
correct, creates a Modbus/TCP application data unit and encaps ulates it into an Eth ernet frame an d
sends it out the Ethernet port over the appropriate sock et. The ENET-710 also handles command
time-outs on the serial port network. In the case that a seri al device fa ils to respond, th e ENET-710
replies to the client with a Modbus/TCP timeout exception code. In the case of an inval id response
from a Modbus/RTU slave (including bad CRC), the ENET -710 will ignore this response and the
client must perform the error handling. The ENET-710 will also respond back to the client with a
Modbus/TCP exception code if the client tries to access a devic e address that does not exist in the
current ENET-710 configuration.
CD600 Protocol
In CD600 mode, clients running the CD600 Confi guration software can communicate ov er Ethernet
to one or more CD600 Multi-Loop Controllers using the RS-485 port on the CD6 00. Configure the
selected ENET-710 serial port to match the serial port settings of the C D600, the CD600 device
address, and choose the CD600 serial protocol.
Configuration Web Page
The user configures the module with the configuration menu. The menu i s accessed v ia a web pag e
using a web browser over the Ethernet connection. With this menu, the user can configure all five
serial ports for desired baud rate, character format, and serial protocol. Also the user sets up the
address range of devices connected to a particular serial port and device response timeouts.

ENET-710 – User’s Manual
Serial Port Configuration
To set up any of the five serial ports, click on one of the Configure Port X (where X is 0,1,2,3, or 4)
buttons on the main menu. The port configuration menu for port X is seen belo w (all 5 ports similar).
Choose the desired serial protocol, either Modbus/RTU or CD600. Select the serial baud rate and
character format (parity, stop bits). Parity can be even, odd, or none. You may choose 1 or 2 stop
bits. Set up the serial device address ranges by entering the range low address into the First
Address box and the range high address into the Second Address box. Enter desired device
response timeout into the timeout box. Finally, click on the Submit button to save the new
information.
Notes:
• For a particular serial port, any and all sl ave devices connected to it must all b e set to the
same parameters that were selected for the serial port.
• When selecting 2 stop bits for a port, the ENET-710 will ignore the parity setting in the
menu and use no parity.
• W hen selecting the CD6 00 protocol, the par it y and number of stop bits settings ar e ignore d
by the ENET-710.
• The same address range must not be repeated wh en setting the ENET-710 ports. F or
example, there are 20 devices in the configuration. So, the address range for the
Port 0 is from 1 to 20, and for the Port 1 is from 11 to 20.
IMPORTANT
Ports using the same protocol cannot have any repeated addresses.
RS-485 Port Operating Modes
To set up the RS-485 port operating modes, select the Set Channel Operating Modes button o n the
main configuration menu. Here a redundant mode configuration for the RS-485 ports can be
enabled. The serial port pairs 1-2 and 3-4 can provide redundant operation in case the connection of
one member of the pair fails. The modes include Independent (no redund ancy), Parallel, and Ring.
The menu is shown.
10
Figure 5 – Configuring the ENET-710 Ports
ENET-710 – User’s Manual
Figure 6 – Configuring the RS-485 Ports
The parallel mode involves using a separate serial cable connected to each module serial port in the
given pair. The slave devices need to have two serial port s with one port connected to one of the
serial cables in the pair and the other port connected to the remaining cable in the parallel pair.
When using the parallel mode, if a problem deve lops on a give n modul e s erial port, the n the oth er in
the pair can seamlessly take over the required serial communications.
When using the parallel mode, the two ENET-710 serial ports in the pair may be configured with
different serial port settings. However, slave device ports connected to a given port in the pair must
be configured the same as the ENET-710 port to which they are connected.
When using the ring mode, a single serial cable loops from one modu le serial port in the pair to the
other port. Slave devices are then distributed alo ng the cable in between. If a problem develops
along the cable or with the module serial port isolating one or more devices from the primary port,
then the other port in the pair can take over the needed communications to those devices. Both
serial ports in the pair and the slave devices must be configured with the same protocol, baud rate,
and serial character format. In this mode, the slave devices need only have one serial port.
For both parallel and ring mode, the operation is as follows: if communication is directed to an
address that is configured to be on one port of the pair but there is no response, the ENET-710 will
then try to communicate to the device using the other port in the pair.
Choose the desired mode of operation and click the Submit button to enable the setting.
Changing the IP Address and Username/Password
To change the login username/password pair or module IP address, select the Lo gin Information
button on the main menu. This brings up the page to setup the desired IP ad dress and subnet
mask, plus the username and password. Note that the username and pas sword are cas e sensitive.
To change any of these, enter the new information and click th e Submit button to save. See the
figure below.

ENET-710 – User’s Manual
Default Switch
Figure 7 – Changing Username and Password
If after configuring a new IP address or username/pass word, if the module fails to respond to the
new information, make certain that the defaults switch is off (see Defaults Switch section, below, for
more information). Otherwise, verify that the client PC is on the same subnet as the new settings for
the ENET-710.
The ENET-710 default configuration consists of the IP ad dress of 192.168.1.1, a subnet mask of
255.255.255.0, and a username of admin with no password set. In case of a lost or forgotten
username/password or IP address, turn on the switch accessed through t he air vent opening o n top
of the module by sliding the switch toward the back of the module with the module po wered. This is
the “Set Defaults” position and will cause the module to temporarily us e the default configuration.
The module will continue to use this configuration for as long as the switch is on. Note that the
default switch does not clear the previously set configuration. You may then access the
configuration web page using the default configur ation and read the lost username/password or IP
address information and/or store new information. Slide the defaults switch off to allow the module
to once again use the stored information.
