MOMA Alerts
A MOMA Alert is defined as a notification of certain parameters of interest in a single MOMA Test. This page details the logic we use to extract the data for each alert. Note that this is the master reference, which means the engineers and scientists should ensure that the logic detailed here is correct. All alert data is in an Alert Panel within a typical TID record __TOC__
General Error Check
Severity : Notice
- Message Log is parsed for the phrase 'Error' while excluding messages that contained 'Holding at stop for operator' or 'error =' <- Means a value was being set.
MAIF APV Comm Check
Severity : Warning
- Message Log is parsed for the phrase 'ldi: error'.
Spacewire Comm Error
Severity : Warning
- Spacewire Disconnect (HK 522) > 0 or Spacewire Parity (HK 523) > 0 after 30 sec.
Severity : Notice
- Spacewire Disconnect (HK 522) > 0 or Spacewire Parity (HK 523) > 0 only before 30 sec.
MOMA Safe Event
Severity : Notice
- MOMA_STATUS_SAFE (HK 507) is 1 at any time during the TID.
WRP Too Fast
Severity : Notice
- PWM Speed (HK 832) > 103000RPM at any time during the TID.
