6.0 EXTERNAL COMMUNICATION—BUILDING MANAGEMENT SYSTEMS, LIEBERT
SITESCAN
®
Liebert iCOM is capable of communicating with external monitoring systems, such as Building
Management Systems (BMS), Network Monitoring Systems (NMS), Liebert's SiteScan
®
Web and
others.
Each Liebert iCOM-controlled cooling unit is equipped with Liebert IntelliSlot
®
plug-in slots for use
with optional communication cards. The hot-swappable plug-in cards provide interfaces supporting
open protocols, including:
• Emerson Protocol for Trellis
™
, Liebert SiteScan
™
and Liebert Nform
®
• Embedded LIFE
™
Technology for Remote Service Delivery
• SNMP (v1/v2c/v3) for Network Management Systems
• HTTP/HTTPS for Web page viewing
• SMTP for e-mail
• SMS for mobile messaging
• Modbus RTU-Modbus Remote Terminal Unit (RTU) communication protocol for Building
Management Systems over a RS-485 serial network (also called Modbus RTU RS-485)
• Modbus TCP-Modbus Transmission Control Protocol for Building Management Systems over an
Internet or LAN
• BACnet IP—BACnet over Internet Protocol for Building Management Systems over the Internet
or a LAN
• BACnet MSTP—BACnet Master-Slave/Token-Passing (MSTP) communication protocol for
Building Management Systems over an RS-485 serial network (also called BACnet MSTP RS-485)
Velocity V4 monitoring protocol is required to ensure monitoring connectivity with all the protocols
mentioned above. Velocity V4 protocol is standard in Liebert iCOM software version PA1.04.033 and
later.
Liebert iCOM software versions PA1.04.022.STD and older, which shipped before November 2010,
will support Velocity V3. Older Velocity V3 cards will become obsolete with the advent of the Velocity
V4 protocol and the newer Liebert IntelliSlot cards that communicate with this protocol. See
Table 19 for information about software versions, card compatibility and supported protocols from
each card.
Another communication option is the Liebert IntelliSlot SiteLink-E
®
CARD (IS-485EXI), which
provides ground fault isolated connection to a Liebert SiteLink-E for monitoring and management.
See the Liebert Web site for the latest supported protocols, monitoring reference information and
SNMP MIBs: www.liebert.com
