2.3 Description of System Environment
There are different possible system environment configurations for the communications between
the management station and ELMS devices. Figures 2-2, 2-3, and 2-4 show example views of
how some of the basic system elements can be configured.
Figure 2-2 depicts a situation where management stations (center or field based) interact with a
Data Logger located in the field that is hosting an SNMP agent. The Data Logger in turn
communicates with other field devices using non-NTCIP based protocols.
Figure 2-2. Data Logger with SNMP Agent Example Configuration
Figure 2-3 shows a different example configuration, in which the SNMP agent is hosted with the
Luminaire devices. The management stations (center or field based) interact directly with the
SNMP agent hosted with the Luminaires.
