To reply to increasing needs of manufacturers for equipments that can be integrated in their
industrial field buses, Coval releases the LEMCOM, a « connected » evolution of the compact
vacuum pump LEMAX.
LEMCOM can easily be integrated to the existing field bus without requiring gateway or any other
specific interfaces.
The master LEMCOM uses EtherNet/IP to communicate with a programmable logic controller. An
embedded 2-port ethernet switch allows installer to connect additional EtherNet/IP capable products
in series (or an additional LEMCOM island).
STANDALONE MASTER ISLAND OF SECONDARY MODULES STANDALONE SECONDARY MODULE
Figure 1 –Master/Secondary concept
-1 Master can control up to 15 Secondary modules.
-Island assembly or standalone modules for flexible integration (close to the application).
-Communication between the master LEMCOM and the controller is based on the CIP
“producer/consumer” model.
-Master Secondary Module communication through « Coval Bus » (CAN support,
proprietary communication protocol)
-24V DC is supplied to all LEMCOM via the back M8 connector of the last module of the
island.
-Master module is also a vacuum pump and not only an « EtherNet/IP head »; it can be used
as a standalone module without any Secondary module connected to it.
NOTE
Secondary modules are identical whatever the fieldbus protocol (EtherNet/IP™,
CANopen®, etc.) used between the master module and the controller.

Figure 2 –Island overview
3.1 Power supply connector
To end the COVAL Local Bus, it is mandatory to use the M8 termination provided with
any LEMCOM island (to be ordered separately for customized configuration). This specific
interface must be inserted in between the last Secondary module back connector and the
power supply cable. It ensures a good reliability of the COVAL Bus communication
(integrated 120 ohms termination resistor) and separates the communication lines from the
power supply.
The termination is not required for a standalone master module used without any
secondary modules.

Figure 4 –Wiring instructions (M8 –Coval bus connector)
Connection between LEMCOM modules is done with a M8 / M8 cable (female-
female) or, if assembled as an island, with a specific M8 / M8 bridge.
The maximum overall length for COVAL Bus is 20 meters.
3.3 Ethernet ports
The master EtherNet/IP LEMCOM embeds a fast Ethernet 2-port switch. Field bus can be connected
to one of the two ports and the other is available to connect another EtherNet/IP capable device in
series (either another LEMCOM or a motor, encoder, etc.).
Figure 6 - Wiring instructions (M8 –Ethernet connector)
The same wiring standard as EtherCAT has been chosen to allow installers to get M8 / RJ45 cables
from connectors and cables suppliers such as Phoenix Contact, Beckhoff, Weidmüller, Igus, etc.
M8/RJ45 ETHERNET CABLE –Shielded –CAT 5
The following Coval references (M8 4-pin straight IP67 /
RJ45 4-pin straight IP20) can be used:
CDM8RJ45L2 2 meters
CDM8RJ45L5 5 meters
(0.2 to 40.0m length available upon request)
SHIELDED CABLES
It is highly recommended to use shielded CAT-5 cable (with STP, Shielded Twisted
Pair) to connect the master pump to the network.

CONFIGURATION TOOLS
LEMCOM modules can easily be configured, updated, controlled and diagnosed remotely using one
of the following tools:
Universal PC software dedicated to
configuration, update, control and
diagnostic of all LEMCOM vacuum
pumps of the factory.
Compatible with all LEMCOM protocols.
Embedded web server that allows
configuration, update, control and
diagnostic of one given LEMCOM
island.
No software installation required.
LEMCOM MANAGER & WEB SERVER
Please refer to the specific user manuals LEMCOM-Manager-xx-x-1155UM0069 and
LEMCOM-Web-Server-xx-x-1155UM0070 for detailed information on the PC software

NETWORK CONFIGURATION
Either you use a standalone master module or an island, the first step before using LEMCOM is to
set the network settings of the master module to make it “visible”on the factory network.
6.1 Computer network settings
To make first configuration easier, it is recommended to use a direct cable connection (M8 / RJ45)
between the computer that will be used for configuration and the master LEMCOM.

Considering it is the first time the LEMCOM is used, its default network settings are:

The computer network settings have to be set according to those of the LEMCOM:
1) Click the Start button.
2) Select Control Panel.
3) Click the Network and Internet link.
4) Click the Network and Sharing Center link.
5) View your network connections; click the Change adapter settings link.
6) Right-click your local area connection.
7) From the drop-down list, select Properties.
8) Under "This connection uses the following items," select Internet Protocol Version 4
9) Click the Properties button
10)Fill in the window as shown here 
11)Press OK button.
12)If not done yet, connect the LEMCOM to the
computer Ethernet port and to the power supply.
6.2 LEMCOM network settings
6.2.1 Using LEMCOM Manager
1. Launch LEMCOM Manager
2. Select the “Configuration mode”, enter the password “coval” and click OK
3. Select “EtherNet/IP”
4. Connect to the master module by selecting default IP 10.3.182.163 and click OK
5. Click on the ‘setting wheel’ to access network settings screen

COVAL - LMEIP-UK-D-1155UM0067 17/42
6. Set new IP address and other network parameters
7. Master module restarts when “OK” button is pressed then LEMCOM Manager automatically
tries to reconnect to the LEMCOM (however, reconnection would fail if computer and
LEMCOM are not on the same network anymore).
The LEMCOM can now be connected to the factory or machine network.
6.2.2 Using LEMCOM webserver
Not implemented yet.
6.3 Reset LEMCOM’s IP address
LEMCOM’s IP address can be set back to its default value (10.3.182.163):
1. Unplug LEMCOM from the 24V DC power supply.
2. Press and hold the ‘SET’ button on the front panel of master LEMCOM.
3. Plug back in the power supply.
4. Release the button when MS led starts to blink.
IP address is now 10.3.182.163.
6.4 LEMCOM MAC address
Any LEMCOM master module can be identified on the ethernet network by its unique hardware
address, the MAC address.
The Coval OUI (Organizationally Unique Identifier) is 20:5A:00 so all LEMCOM MAC addresses
follow the format 20:5A:00:xx:xx:xx (where xx:xx:xx is an incremental and unique value).
The MAC address is written on the left side of the LEMCOM master module and can also be read
using LEMCOM Manager.
