Goals

  • improve the stability of the DAFNE orbit acquisition system.

Overall strategy

  • develop and debug the new DEVIL204 along with the regular run of the legacy system;
  • get rid of the phisical DEVIL204 by moving its code to a virtual machine;
  • get rid of the 4 LEXTEL couples by employing the SIS3153 VME Ethernet controllers.

Description

Due to safety reasons, the development of the new DEVIL204 takes place on the virtual machine vldantedev038 that temporarily mounts a copy of the dcs_lv12/source_linux actual directory.
Any VIs and data files created/modified/removed concern the directories:

/u2/dcs/source_linux/0_classes/GOD/
/u2/dcs/source_linux/devils/DISARMED/DEVIL204-NEW/
/u2/dcs/source_linux/lib/lv-vme-chaos-driver/

Any derogation from this assumption will be highlighted.

Repo git della librearia di accesso alla SIS3153, clonato in: /u2/dcs/source_linux/lib/lv-vme-chaos-driver
(dovrebbe stare nella /usr/local/natinst/LabVIEW-2012/user.lib/ ma questo andrebbe poi fatto su tutte le macchine. Messo invece nella .../source_linux/lib/ , di modo che valga per tutti).

Warnings and Fixes to be done

GGODSta.vi and GGODDyn.vi have the "append" and "write" cases DISABLED to avoid memcached real write operations

To be done

I DBFiles dei DEVILs 364, 365, 366, 367 sono sbagliati (il DEVIL365 ha 24 componenti e NON 23 come scritto nel DBFile Solaris). 

The VIs .../0_classes/GOD/library/fetchORB[Sta|Dyn].vi and their SubVIs .../0_classes/GOD/library/bundleORB[Sta|Dyn].vi must be optimized by moving the code that parses the descriptors in the "init" frame so that it is executed only once.

Al momento la difficoltà maggiore è quella di riottenere una tabella di ordinamento tramite i VIs:
precompileORB.vi
precompileORB_IR.vi
I suddetti VIs sono stati modificati per quanto riguarda il recupero degli indirizzi ma ci sono degli errori.

GGODSta.vi

This global is initialized with data from the DBSta file. The DBSta file contains dummy data (all zeros) and is only used to correctly size the arrays.
The filling of the global with actual data is done via the foo program GODStartup.vi using the file:

The VME access is A32, D32 and "block transfer" is enabled.
The VME mapped size is 4 MByte (that is the whole Apple DEVIL memory).
The vme_base_address is set to E0000000 (which is the DEVIL extended base address).

Details

Each one of the 4 DEVILs has a circular buffer of 1927 lines named "sockets". Write operations of the four circular buffers are synchronized via a common stobe so that the four write pointers are always alligned. At each strobe, each DEVIL stores a "socket" composed as:

  • part X

[DBL]   32 values of the BPM X signals from the Bergoz modules read from that DEVIL;

  • part Y

[DBL]   32 values of the BPM Y signals from the Bergoz modules read from that DEVIL.

The 32 components in part X and Y are ordered according to the cabling and do not necessarily follow the sequence of the BPMs along the vacuum chamber. Moreover the 32 values refer to both e- and e+ rings for which the BPMs sequence is obviously different. As a consequence, part X and Y must be considered as raw containers and their content must be further processed in order to reconstruct the real orbit.

  • Header
DBL   ACQNum [0, 1926];
DBL   timestamp (LabVIEW Time Stamp cast to DBL).
      example: 00:00:00.000 PM
               MM/DD/YYYY

The socket header is written twice: at the beginning of the socket (before part X) and again in the middle of the socket (before part Y) the content of the two headers being the same; this is due to historical reasons and – although it is a waste of memory space – it was left in order not to compromise the functioning of other pieces of code that access the same memory area.

[init, read, write X and Y, write X, write Y] (read)

  • init: the internal shift register are initialized (all zeros);
  • read: returns "part X" and "part Y" from the arrays specified by "DEVILIndex";
  • write X and Y: stores simultaneously"part X" and "part Y" into the arrays specified by DEVILIndex. Both inputs must have 32 components otherwise no one of them will be stored;
  • write X: stores "part X" only to the buffer specified by DEVILIndex. The array must have 32 components otherwise it will not be stored. The "part Y" array is kept unmodified;
  • write Y: stores "part Y" to the buffer specified by DEVILIndex. The array must have 32 components otherwise it will not be stored. The "part X" array is kept unmodified.
