LEMCOM overview
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.

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.

Description
Comments
Used to send vacuum and blow-off commands to all the modules of a LEMCOM island, i.e. to the master module
and to the 1 to 15 Secondary modules that may be connected to the master. Vacuum and blow-off are independent
which means that vacuum can be activated at the same time as blow-off (might be useful for high speed
application).

another.
Settings are applied to the LEMCOM modules only when the first bit of the “Settings modification allowed” byte is
set to ‘1’.
WARNING: never maintain “Settings modification allowed” bit to ‘1’ all the time, this would constantly
update all LEMCOM units parameters and overwhelm master module (communication loss or
vacuum/blow-off commands hazards).
LEMCOM settings modification must be done carefully while machine is not running.

Comments
Used to get “Object gripped” information of all the modules of a LEMCOM island. Each bit of
the 2 bytes word corresponds to a module. Bit = ‘1’ means that the product handled by the
corresponding LEMCOM module is gripped (vacuum level is above L1 threshold).
This input instance also includes a Heartbeat byte. This helps users to monitor Ethernet
communication status between PLC and LEMCOM.
Contains same data as instance 101 and the Vacuum level values of all the modules of the
island (Master module and secondary modules at address 1 to 15). Vacuum level is given in
percent vacuum (0 to 99%).
Input assembly 140 gives some more diagnostic data of the LEMCOM island such as:
A list of the connected modules (island composition)
Alarm signals for regulation, lost part, power supply, etc.
All diagnostic data are coded in a 2 bytes word where each bit corresponds to the 1 to 16
LEMCOM modules that may be on the island (1 master and up to 15 secondaries).
Contains same data as instance 140 + the complete diagnostic data related to the module
selected in the last byte of instance 111.

Comments
The assembly 160 is used to transfer the vacuum settings to all LEMCOM of an island (1 to 16 modules). The
parameters are sent to the master LEMCOM at PLC startup, when the communication with the unit is established.
Please note that, unlike LEMCOM Manager that warns user in case of incorrect parameters, the configuration
assembly lets the user sends any settings. That may lead to the apparition of warnings on the modules front panels
(for example: threshold or hysteresis set to 0).

VACUUM CHARACTERISTICS
9.1 Global overview
LEMCOM is a compact, energy efficient and connected vacuum pump thought to be easily
integrated closed to the customer application.
It is made of different subassemblies that are specifically chosen to fulfill each application
requirements.
LEMCOM has an integrated regulation function (ASC = Air Saving Control) that automatically stops
air consumption once vacuum is established. Regulation threshold (L2) is
configurable via the PC software and the embedded web server.

LEMCOM EtherNet/IP™ - User manual
Vacuum characteristics
9.2 Typical handling cycle
The following vacuum parameters can be remotely configured using LEMCOM Manager or the
LEMCOM Web Server:
-
L1 threshold / h1 hysteresis
o
o
o
-
Define the vacuum threshold that triggers the “object gripped” signal.
Master LEMCOM periodically collects gripping status of every module it controls and produces a gripping
status message on the EtherNet/IP™ field bus.
Vacuum level value can also be added to the message sent on the bus.
L2 threshold / h2 hysteresis
o
o
Define the vacuum threshold that turns OFF internal vacuum command for air saving purpose.
Only used if ASC is enabled
-
Air Saving Control - ASC (ON/OFF)
o Enable/disable the regulation system
-
DIAG/ECO - DIAG/E (ON/OFF)
o
o
o
-
Enable/disable the system that prevents vacuum valve to turn ON and OFF frequently due to rough or
porous product.
Diag Eco can be enabled only if ASC is ON.
Diag Eco ON: if regulation system turns ON and OFF the vacuum pilot more than 2 times in a second, it
maintains the vacuum command ON until the end of the cycle to avoid useless wear of the pilot.
Auto-blow (ON/OFF) + auto-blow duration (millisecond)
o
o
If turned ON, blow-off is automatically enabled as soon as vacuum command is disabled.
The blow-off duration can be set between 1 and 9999 ms.
The figure below details a typical vacuum cycle with ASC function enabled:

Recommendations
Default vacuum parameters may have to be adjusted to perfectly suit application requirements. If so,
it is recommended to respect the following conditions:
-
L2-h2 > L1
i.e. regulation zone should be above the “object gripped” threshold
h1<L1
i.e. hysteresis should be lower than “object gripped” threshold
h2<L2
i.e. hysteresis should be lower than “regulation” threshold
In case of rough or porous product handling, disable ASC to avoid vacuum pilot to turn ON
and OFF frequently.
INCORRECT SETTINGS INDICATION
If the recommendations given above are not respected when configuring a LEMCOM, the
MS led of the corresponding module will blink red.
