LEMCOM EtherNet/IP™ - User manual
LEMCOM overview
COVAL - LMEIP-UK-D-1155UM0067
9/42
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).

– 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.
