This VI reads and returns the last data acquired from the 4 DEVILs. It doesn't perform any data reordering (see "Details" paragraph below).

booleaninit

T = initialize, F = regular run
init = T: some constant values are loaded into the VI shift registers.

init = F: reads the socket "socketNumber" from the VME memory of the DEVIL "DEVILIndex" and returns the two parts 

I32DEVILIndex

Index in the range [0, 1, 2, 3] corresponding to:

INDEX   0,   1,   2,   3
DEVIL 364, 365, 366, 367
RACK   63,  71,  70,  66
I32socketNumberPointer to the acquisition buffer in the range [0, 1926]
[DBL]part XArray of 32 DBL components containing the raw values of the X signals coming from both electron and positron BPMs. The components are in the same order of the values in the DEVIL memory locations.
[DBL]part YArray of 32 DBL components containing the raw values of the Y signals coming from both electron and positron BPMs. The components are in the same order of the values in the DEVIL memory locations.

When true, the VI does nothing and simply passes the error out.

This VI is a functional global that stores, holds and returns the last X and Y parts acquired from the 4 DEVILs. 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 orbitIt doesn't perform any data reordering.

[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.
