LGʼs BACnet Gateway Agreement
JMT (Joint Matching Test) – This is necessary for every independent BMS.
The case where a JMT is not necessary is where previously a successful JMT has been carried
out and the BMS system has not been updated by software or hardware changes. In the case
that the BMS has updated their system by either changes, a following JMT will be required.
BNU-BAC Diagnosis – Use of LG's BNU-BAC setup-tool is for confirming the operation/state of
connected A/C units & address ID's, prior to connection with the BMS system.
BMS Engineering – Creating of the Points. This is NOT to be done by LG since it is directly related to
the BMS side. The BMS engineer is to carry out the engineering of the Point, however LG is
responsible for providing the method of how the Points are calculated.
Commission – First step, only using LG's BACnet Gateway, without connecting BMS. This is to be
carried out by LG engineering staff with the use of the BNU-BAC set up tool.
Discrepancy of operation of Gateway by BMS - In the case that the BMS maker feels that the
BACnet Gateway is not functioning correctly via the BACnet Protocol, a test with the use of LG's
BACnet Client software can confirm this. (This test is generally not required)
