DAQ

• Message Reporting System (MRS) provides a facility, which allows all software components of the DAQ system to report, asynchronously, events such as error messages.

DCS-DAQ-Communication (DDC)

• DIM: DIM is a communication system for distributed / mixed environments, it provides a network transparent inter-process communication layer.
• PVSS - DIM Integration: The PVSS-DIM toolkit allows to interface PVSS to devices which do not provide any of PVSS's supported protocols (such as OPC).
• The Inlink and In/outlink has to use DDC to execute command to turn on/off optoboard and read Pin current on optoboard back. The failure of DDC will cause abort or readout values -999.

Configuration Tag Utilities

Dump the contents of configuration tag

• Dump the objects of each domain in a given partition

  ${PIX_LIB}/Examples/DbServer_monitor --dbPart PixelInfr_wittgen --dump
  - DbServer has 2 domains
  
    -> domain   Configuration-SR1 has 2 tags
  
       -> tag   NEWDSP-SCHSU-BOC (content: BOC )  has 517 objects
  
       -> tag   TOOTHPIX-ORIG (content: MOD )  has 5940 objects
  
    -> domain   Connectivity-SR1 has 1 tags
  
       -> tag   TOOTHPIX-V4 (content: NULL )  has 172 objects
  

• Dump the objects in the ROD/BOC configuration tag

   ${PIX_LIB}/Examples/DbServer_monitor --dbPart PixelInfr_wittgen --domain Configuration-SR1 --tag NEWDSP-SCHSU-BOC --dump 
  --objMode
  - DbServer has 2 domains
  
    -> domain   Configuration-SR1 has 2 tags
  
       -> tag   NEWDSP-SCHSU-BOC (content: BOC )  has 517 objects
         -> object   ROD_C0_S11
         -> object   ROD_C0_S11_BOC
         -> object   ROD_C0_S11_BOC|PixRx0
         -> object   ROD_C0_S11_BOC|PixRx1
         -> object   ROD_C0_S11_BOC|PixRx2
         -> object   ROD_C0_S11_BOC|PixRx3
         -> object   ROD_C0_S11_BOC|PixTx0
         -> object   ROD_C0_S11_BOC|PixTx1
         -> object   ROD_C0_S11_BOC|PixTx2
         -> object   ROD_C0_S11_BOC|PixTx3
         -> object   ROD_C0_S11_ROD
     

* dump objects of ROD configuration. Let's focus on the slave binary used by this ROD. There are three binaries for OldDsp. For NewDsp, only the general_S_EXTFile is important. We should replace this file with our own NewDsp slave image.

${PIX_LIB}/Examples/DbServer_monitor --dbPart PixelInfr_wittgen --domain Configuration-SR1 --tag NEWDSP-SCHSU-BOC --dumpObj --objName ROD_C0_S11_ROD 
   -> string_map has 3 entries!!
      -- Name:   general_S_EXTFile        value: /home/schsu/DSP/sdsp6713_xcode.bin
      -- Name:   general_S_IDRAMFile        value: /home/schsu/DSP/sdsp6713_idram.bin
      -- Name:   general_S_IPRAMFile        value: /home/schsu/DSP/sdsp6713_ipram.bin
   

Change the content of configuration tag

• We can change the configuration on the fly.
  • startup infrastructure
  • run the ChangeCfg
  • kill the ActionServer to restart it
• Change the prefix directory of the slave binary. After running this command, check the DB content, one can see that the slave binary has been pointed to new path.

  ${PIX_LIB}/Examples/ChangeCfg --dbPart PixelInfr_wittgen --idTag SR1 --save --setBinPref /home/wittgen/DSP --connTag TOOTHPIX-V4 --cfgTag NEWDSP-SCHSU --pendTag OnDb
     

• if you don't like the name sdsp6713_xcode.bin, you can change the source code. ${PIX_LIB}/Examples/ChangeCfg.cxx

      std::cout << (rod->config())["general"]["EXTFile"].valueString() << std::endl;
      (rod->config())["general"]["IDRAMFile"].valueString() = string(prefix + "/sdsp6713_idram.bin");
      (rod->config())["general"]["IPRAMFile"].valueString() = prefix + "/sdsp6713_ipram.bin";
      (rod->config())["general"]["EXTFile"].valueString() = prefix + "/sdsp6713_xcode.bin";
