Deactivated Patch of UA5000 Causes N2000 BMS Power Monitoring Result Is Different from UA5000

Publication Date:  2012-07-24 Views:  2 Downloads:  0
Issue Description
UA5000 devices should be montoring environment and power alarms and send results to BMS. 
But AC power status in BMS was incorrect for one site, even UA5000 result normal. From attachment you can compare results at BMS and UA5000.
We implemented this monitoring process using following network scheme:
BMS<--->IP bear network<--->UA5000_PVM<--->PSD
BMS version is iManager N2000 BMS V200R008B02D061SP10
UA5000 PVM version is V100R013B02D072SP06
Alarm Information
BMS not generated alarm. But when query status of power, AC power status is abnormal. From attachment you can see screenshot of AC power status.
Handling Process
We tried following ways but they are no result.
1. Synchronization
2. Delete config for power monitoring and again reconfigured
PVMV100R013B02D072 'SP06' is dedicated for monitoring environment and power. We activated and runned correct patch. After that, the problem disappeared.
UA5000#patch activate all
UA5000#patch run all
UA5000#display patch all active
  Host version:               PVMV100R013
  Patch version:              PVMV100R013B02D072SP06
  Patch number:               6
  Number of formal patch:     6
  Number of temporary patch:  0
  Number of running patch:    6
  Number of actived patch:    0
  Number of deactived patch:  0
Root Cause
 This problem can be raised by following reasons:
1. AC power status is actually faulted
2. the recovery alarm not created by UA5000 cause BMS can't clear the alarm automatically.
But AC power status of PSD is normal.
Also from log we not find any AC power down and recovered alarms.
While check UA5000 configuration data, we detected UA5000 latest patch was not activated and runned.

Suggestions

During operation should be work carefully.
Also from log we not find any AC power down and recovered alarms.
