Page 3JSOC for SDO MOR October 2007 HK Processing on High Speed bus- More Details

Page 4JSOC for SDO MOR October 2007 HK Processing on High Speed Bus Module Description HK Processing module receives hk VCDUs from the main Level Zero process and decodes and translates hk packets in VCDUs into keywords and values using hk configuration data. A link list structure of keywords and values is returned and saved in a DRMS hk keyword data series. Data series names are based on source (hmi or aia), APID and the JSOC Version Number (i.e., hmi.lev0_0445_0009). Data series are indexed by packet time to make data retrieval easy. HK data is saved in data series in DRMS and archived to tape. HK Processing module saves received hk packet data in VCDUs to dayfiles base on packet APID. Each dayfile is saved on file system and will contain hk packets per APID per day.Status HK Processing is operational in EGSE and needs to be ported to JSOC environment. Need to update code that loops thru VCDU, write function to save hk packets to dayfiles, update write to drms function, integrate with other Level Zero modules, change decode of digital keywords, and add decode of thermistor temperature keywords. 60% complete

Page 6JSOC for SDO MOR October 2007 Real Time HK Extraction Module Description Real Time Extraction module receives real time HK dayfile data from LMSAL. If needed processes hk packets into keyword names and values and writes data to DRMS hk data series. If needed, saves hk packet data to dayfiles on file system.Status Need to program interface to real time stream of HK dayfile data. Need to reuse routines already created to decode hk data and read hk dayfile data. 0% complete

Page 9JSOC for SDO MOR October 2007 Retrieve, Save & Decode Dayfile HK Processing Module Description Retrieve & Save HK Dayfile Processing module gets dayfiles from LMSAL, SDO MOC Product Server, and JSOC(via Level Zero Save Dayfile process) and saves dayfiles to DRMS dayfile data series(i.e., aia.hk_dayfile). These dayfiles are archived to tape. The dayfile data can be easily retrieved from DRMS or tape. Decode Dayfile HK Processing gets dayfiles from DRMS and decodes and translated dayfile data into hk keyword names and values. Keyword names and values are saved in DRMS hk keyword data series. Data series names are based on APID and the JSOC Version Number (i.e., hmi.lev0_0445_0009). The data series are indexed by packet time to make data retrieval easy. The data series’s are save to DRMS and archived to tape.Status Retrieve and Save HK Dayfile Processing is operational for LMSAL day files. Need to setup and update scripts to load dayfiles from SDO dayfiles and Level Zero created dayfiles, change hk dayfile date format from string to integer(yyyymmdd). 70% complete Decode Dayfile HK Processing is operational for loading LMSAL dayfiles from file system. Need to update script for getting dayfiles from DRMS, decode SDO dayfiles using SDO configuration data, and setup processing Level Zero created dayfiles. 60% complete
