TL1 AID Group Tab
You can program up to thirty-two (32) Access Identifiers (AID) and assign a Sub-Access Identifier (Sub- Aid) to the access identifier.
Constraints:
• The AID Name that can also have a Sub AID Name Prefix has a 16 character maximum limit.
• The AID Name + Sub AID Name Prefix also has a 16 character maximum limit.

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 sub-entity within an NMA system, such as a specific rectifier. Only alpha-numeric characters can be entered for
this parameter. TL1 uses specific values for this parameter. Refer to TA-NWT-001360, Table 4.1.
Procedure
1. Select the Access Identifier (AID) to be programmed by selecting the circle next to its number in the list.
