LEMCOM
modules
This guide provides first-time users with information on wiring the different modules of a
LEMCOM island and on setting up the LEMCOM.
I - ELECTRICAL CONNECTIONS
A- Wiring instructions
The LEMCOM vacuum pump must be used with power supply units that provide
a Protective Extra Low Voltage (PELV) and with an isolation of the supply voltage
according to EN60204.
Standalone secondary module or "Secondary only" island?
Refer to chapter VI for wiring and initial setup.
Factory fieldbus (EtherNet/IP™) is connected to one of the 2 ports of the embedded Ethernet
switch (shielded M8/RJ45 cable).
Connect the "COVAL bus" using the provided bridge connectors or M8/M8 female cable for re-
mote modules.
24V DC power supply is connected to the rear connector of the last secondary module of the
island (or to the rear connector of master module if used as standalone LEMCOM) through the
COVAL bus termination cable.
B- Consumption
The LEMCOM structure implies that all vacuum generators connected together on the COVAL
bus are electrically supplied by the same power source. The consumption table(left) must be fol-
lowed when calculating the required power supply voltage and amperage.

    It takes the form of an M8 male/M8 female cable that includes a 120 Ω line termination resistor. It must be integrated on the last secondary of the COVAL bus, between the module’s rear con- nector and the 24 V DC power supply.
  • Page 3 The IP address of the LEMCOM master module is factory set to 10.3.182.163. In order to use the LEMCOM, its IP address must be set up according to your net- work configuration. 1- Plug the power supply to the last secondary module or to the rear connector of the master module (if standalone LEMCOM).
  • Page 4 L1/h1 35 % / 10% 65 % / 10% The LEMCOM provided to you has been configured with default settings that suit most appli- cations. Depending on the chosen model (LEMC60X or LEMC90X), the LEMCOM module is L2/h2 45 % / 10% 75 % / 10% configured as shown opposite.

  • Page 6 #16 to avoid any address conflict. User must assign a valid and unique address (#1 to #15) to each secondary module to make them “visible” on the COVAL bus. LEMCOM Manager software or web server can be used to complete this operation.
  • Page 7 Lost part alarm (2 bytes) Regulation error alarm (2 bytes) In this assembly, the first bit of byte 5 allows or rejects the modification of the LEMCOM module’s 30MCycles alarm (2 bytes) settings. When it is enabled, the parameters data set defined in bytes 6 to 73 are automatically...
  • Page 8 A - Setup using LEMCOM Electronic Data Sheet (EDS) Installing a LEMCOM EDS file for the EtherNet/IP Module to be identified by Rockwell’s RSLinx software makes programming easier, since the EDS file describes the objects, attributes and ser- vices available in the device.
  • Page 9 1-1 Add a new Generic Ethernet Module to your project. 1-2 Give a name & description to the module, select the Comm Format SINT, enter LEMCOM’s IP address and based on the tables of I/O assembly instances provided above, fill in the con- nection parameters.
  • Page 10 LEMCOM modules can easily be configured, updated, controlled and diagnosed remotely using one of the following tools. This flexibility enables LEMCOM users to adapt their modules to any type of application without needing to perform any operations directly on the vacuum generators.
