editable audit trail.

In the standard RTU configuration, the audit trail is disabled. You can enable audit trail

logging by editing address 010313 to 300 at the keypad, or by using Talon software.

The maximum memory allowed for audit trail is (300 records * 24 = 7,200).

Once enabled, the RTU maintains the audit trail file with a maximum of 300 records.

You can upload the information from the unit to a portable or host computer, using

Talon software. Once the audit trail is full, Audit Trail Full will appear if editing is

attempted and the RTU will not allow any changes; the audit trail must first be

uploaded and reset using Talon software.

Memory (History Logging)

The XARTU/5 has a total of 512Kx16 Z-RAM for database, audit trail, and history

logging. With the large memory capacity, over 1,010,902 bytes of non-volatile memory

is reserved for storing database, audit trail, and historical meter data. The non-editable

history file provides the user with time related data logged in any variation of selectable

intervals; minute, daily, weekly, and monthly. An event-driven history mode allows the

logging of data when an event occurs (e.g. alarms). An experienced user of Talon

software can define the type of data and collection period. Since the history data

elements are stored in a block of memory, the size has to be assigned at the time the

history process is created in the RTU - typically when the database is downloaded at the

factory.

The memory required to store an entire history process data block is [Max pointers *

(Max Record +1) *4].

Data may be collected over the telephone lines via the optional modem, or on-site

through the enclosure MS connector (Talon software is required for collection). The

collected data can then be used for:

 Billing information

 Measurement reports for utility and customer management

NOTE

Once the audit trail is enabled (a value greater than “0”), the user cannot disable the audit trail

without a full unit initialization. Reloading the database will not disable the audit trail.

NOTE

The size of the history block cannot be changed once the history process has been created in the

unit. A complete download would be required to reset the database and change the RTU’s

memory assignment.
