Performing Remote Analysis (TNS)

Check for TNS errors that may have occurred because of commands 

time-out, or any software related issues in TNS that may have prevented 

AMR commands processing.
For more information on time-out issues, see the Encode Command 

Parameters section in the TNS System Maintenance chapter of the TNS End 

User Guide.

Perform an On-Request AMR command to determine if the unit 

communicates. (This command communicates to the unit by serial number 

to eliminate a two-way addressing issue.)
For more information about On-Request meter reads, refer to the 

appropriate sections in the TNS End User Guide and the TNS Operational 

Process Guide.
A site visit is not required, and you may stop this procedure if the meter 

communicates.  If the meter communicates, check two-way addressing.  

(For more information on two-way addressing, see the Function-Group 

Addressing chapter of the TNS Operational Process Guide and the 

Two-Way Addressing section in the TNS Generic Applications chapter of 

the TNS End User Guide.) 

Check for other TWACS meters that are reading on the same distribution 

transformer, or a nearby meter to narrow the communication problem area.

Check the Customer Information System for a disconnected status that may 

not have updated in the TNS database. If the meter was disconnected, no 

action in TNS is required, but you may want to change the cycle number.
The TNS Operator must have some process for dealing with a meter that no 

longer provides a read. The TNS Operator might consider setting up a 

special cycle (e.g. cycle 99) for disconnects and continue reading the 

meters. Having the disconnected meters in a special cycle allows the TNS 

Operator to isolate meters to scan for usage. If a Customer Service 

Representative re-activates the service and the notification fails to reach the 

TNS Operator, or if a customer tampers with the meter and reconnects the 

service, the TNS Operator can quickly identify a successful read in a group 

of meters where reads should normally fail. Using this configuration, the 

TNS Operator can quickly investigate the reason for the successful read of a 

supposedly disconnected meter.

Check for switching events which may have occurred in the system that 

possibly changed the communication path of the meter. (A communication 

path may have changed due to a physical move or a temporary switch to a 

different substation, phase, or other path component.) If the communication 

path has changed, you can use Pathmaps to update the TNS database.
For more information on communication paths, see the Adding Meters 

Interactively section in the Searching Meters chapter of the TNS 

Operational Process Guide. For more information on Pathmaps, see the 

Alternate Pathmaps Search chapter in the TNS End User Guide and the 

Building and Searching Alternate Paths chapter in the TNS Operational 

Process Guide.
