VT1422A Command Reference 239
ALGorithm
ALGorithm[:EXPLicit]:ARRay?
ALGorithm[:EXPLicit]:ARRay? ’<alg_name>’,’<array_name>’
returns the
contents of <array_name> from algorithm <alg_name>. ALG:ARR? can return
contents of global arrays when <alg_name> specifies 'GLOBALS'.
contents of global arrays when <alg_name> specifies 'GLOBALS'.
Parameters
Comments
•
An error is generated if <alg_name> or <array_name> is not defined.
•
When this command is sent to an Agilent/HP E1406A command module, the
Definite Length Arbitrary Block response data will always use "Big Endian"
(Motorola) byte ordering for the packed 64-bit float values.
(Motorola) byte ordering for the packed 64-bit float values.
•
Returned Value: Definite length block data of IEEE-754 64-bit float
•
Send with VXIplug&play Function: hpe1422_cmdReal64Arr_Q(...)
ALGorithm[:EXPLicit]:DEFine
ALGorithm[:EXPLicit]:DEFine ’<alg_name>’,[<swap_size>,] ’<source_code>’
is used to define control algorithms and global variables.
Parameters
Comments
•
Use VXIplug&play function: hpe1422_downloadAlg(...). This function loads
an algorithm from a file. The VXIplug&play Soft Front Panel program allows
algorithms to be created and tested on-line, then to be stored as files.
algorithms to be created and tested on-line, then to be stored as files.
•
The <alg_name> must be one of ALG1, ALG2, ALG3 etc. through ALG32 or
GLOBALS. The parameter is not case sensitive. 'ALG1' and 'alg1' are
equivalent as are 'GLOBALS' and 'globals'.
