Generator Sequencing
Machines can be added or removed from the power system based on load demand. The following criteria
should be considered before adding or removing a machine:
 Machine
Priority
 Engine Run Time
 Machine
Size
 kW% of the load/demand
 Out of Service machines
Communications
The LSM-2020 communication ports include CAN terminals and an Ethernet port.
CANbus
A Control Area Network (CAN) is a standard interface that enables communication between the LSM-
2020 and the DGC-2020.
Ethernet Port
An Ethernet port provides communications via BESTCOMSPlus to the LSM-2020 and to the DGC-2020
that the module is connected to. Ethernet communication between LSM-2020s allows for generator
sequencing on an islanded system. Firmware updates to the LSM-2020 are made through the Ethernet
port. Firmware updates to the DGC-2020 are only available through the USB port of the DGC-2020. Refer
to Section 4, BESTCOMSPlus, for information on configuring Ethernet communication and updating
firmware in the DGC-2020.
Industrial Ethernet devices designed to comply with IEC 61000-4 series of specifications are
recommended.
BESTCOMSPlus SOFTWARE
BESTCOMSPlus provides the user with a point-and-click means to set and monitor the LSM-2020.
Installation and operation of BESTCOMSPlus is described in Section 4, BESTCOMSPlus Software.
LSM-2020 Plugin for BESTCOMSPlus
The setup utility that installs BESTCOMSPlus on your PC also installs the LSM-2020 plug-in. Refer to
Section 4, BESTCOMSPlus Software, for information on activating the plugin.
The LSM-2020 plugin is used to set device security and view device information such as firmware version
and serial number.
LSM-2020 operational settings are found in the DGC-2020 plugin for BESTCOMSPlus. Refer to Section
4, BESTCOMSPlus Software, for a detailed description of each setting.
The LSM-2020 plugin has two screens: Device Info and Device Security Setup.
Device Info
Information about a LSM-2020 communicating with BESTCOMSPlus can be obtained on the Device Info
tab of BESTCOMSPlus.
Select application version A when configuring LSM-2020 settings off-line. When on-line, read-only
information includes application version B , boot code version C , application build D , serial number E ,
application part number
F
, and model number
G
.
BESTCOMSPlus device information values and settings are illustrated in Figure 8-1.
