Access Identifier
In an NMA system, a unique access identifier (AID) is used to identify each entity contained within the system. The system must be
configured to allow a single access identifier to be used to access and report on an NMA system entity which may consist of a multiple of
sub-entities, each monitored individually by the NCU. This is accomplished by configuring NCU access identifiers and NCU sub-access
identifiers as described next. A list of access identifiers and sub-access identifiers appears in TA-NWT-001360, Table 4-1.
NCU Access Identifier
Thirty-two (32) NCU access identifiers can be programmed into the NCU. The access identifier is used to uniquely identify a system entity
(such as rectifiers contained in the power plant).
NCU Sub-Access Identifier
The system sub-access identifiers are used to uniquely identify each sub-entity of an entity (such as each rectifier, each battery string, etc.
contained in the power plant). This parameter applies only to TL1 commands/messages. The sub-access identifier identifies a specific
