7. 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.
8. Check the Alternate Substation tables for up-to-date information on
Alternate Substations that can feed the primary sub.
For more information on Alternate Substation tables, see the Adding
Alternate Substation Information section in the SCE Maintenance chapter
of the TNS End User Guide. Also see the Alternate Substation Mapping and
Creating and Using Alternate Path Tables sections in the Building and
Searching Alternate Paths chapter of the TNS Operational Process Guide.
Performing Remote Analysis (TWACS NG)
Complete the following steps to determine if a field visit is required for an
unresponsive meter. You can end the procedure at any step and correct the problem
when a cause of failure is determined.
1. If communication fails to the transponder, check the path and search state of
the transponder. You may do this by going to System Monitoring > Edit
Path > Search States.
2. Type in the serial number of the transponder, and click Lookup.
If the transponder is currently in the New, Lost or Tentative path state, the
the TWACS NG will need to search the transponder. The TWACS NG
Operator will need to be sure that it is in a search state of Ready. The search
batch job should automatically pick up the transponder for search when the
next job runs.
3. If the transponder is in a Good/Done state, the TWACS NG Operator may
issue a ping to the transponder. You may do this by going to System
Monitoring > Test Transponder screen.
4. Type in the serial number or Meter/End Device ID, and click Ping.
If the ping is successful, communication to the transponder is successful and
has been verified. If the transponder is still not functioning as expected, a
field visit will most likely be necessary.
5. The TWACS NG Operator may also want to check the notifications to
verify if any have been received for the transponder in question. For more
information regarding notifications, refer to the Notifications section of the
TWACS® Network Gateway Operational Process Guide.
