Syntax

Example

Description/Remarks

New or changed in GainSeeker version

stdspc.cntrllimitcannotbelessthanzero  

stdspc.cntrllimitcannotbelessthanzero = False

This example would tell GainSeeker that the control limit for this standard can be less than zero.

Gets/Sets if the lower control limit cannot be less than zero. Setting this affects the stdspc.vflags value.

False: Control limit can be less than zero.

True: Control limit cannot be less than zero.

stdspc.deconstant

stdspc.deconstant = ".7"

Gets/Sets the data entry constant for the standard.

Character length is maximum 10 characters. Characters over that amount are truncated.

stdspc.description

stdspc.description = "My Description"

Gets/Sets the description for the standard.

Character length is maximum 14 characters. Characters over that amount are truncated.

stdspc.dmspart

stdspc.dmspart = "A-50 INSERT"

Gets/Sets the DMS part number associated with the standard. This value is not stored unless stdspc.dmsprocess is also set.

Character length is maximum 30 characters. Characters over that amount are truncated.

stdspc.dmsprocess

stdspc.dmsprocess = "M-CUT OFF"

Gets/Sets the DMS process associated with this standard. This value is not stored unless stdspc.dmspart is also set.

Character length is maximum 14 characters. Characters over that amount are truncated.

stdspc.exists(stdname)

if stdspc.exists("1250 TEMP"):

print "That standard exists."

Returns True if a standard exists with the specified name. Otherwise it returns False.

stdspc.exists(stdname, idx)

if stdspc.exists("1400 CUT OFF", 3):

print "Found for short run indexed on trace field 3."

Returns True if a standard or short run process specification exists with the specified name. Otherwise it returns False.

idx must specify which traceability field is used for the short run index and must be one of the following integer values:

1 - 6 : short run indexed on traceability field 1 - 6; stdname is a short run process specification

0 : not short run; stdname is an SPC standard

9.4

stdspc.exponent

stdspc.exponent = 7

Gets/Sets the exponent used with this standard (used with exponential notation).

Values between -100 and 100 are valid.

Values outside this range cause an exception and the script halts.

stdspc.getprioritylist()

stdspc.getprioritylist()

Returns the priority list of SPC standards for the currently logged-in user.

The return value is a list. If the current user does not have a priority list of SPC standards, this returns an empty list.

9.2

stdspc.loadstd(stdname)

if stdspc.exists("1250 TEMP"):

spc.loadstd("1250 TEMP")

Loads all information for the specified standard. This resets all previously set values.

stdspc.loadstd(stdname, idx)

if stdspc.exists("1400 CUT OFF", 3):

spc.loadstd("1400 CUT OFF", 3)

Loads all information for the specified standard or short run process specification. This resets all previously set values.

idx must specify which traceability field is used for the short run index and must be one of the following integer values:

1 - 6 : short run indexed on traceability field 1 - 6; stdname is a short run process specification

0 : not short run; stdname is an SPC standard

Note: This also clears the standard name.

stdspc.rtcheck

This example sets the standard to check: x-bar above control, x-bar below control, range above control, range below control, x above spec, and x below spec.

Gets/Sets the integer representation of the real-time checks to perform during data entry for the standard.

stdspc.rtchecklist

Character length is maximum 30 characters. Characters over that amount are truncated.

stdspc.stdvar4

see: stdspc.stdvar1

Gets/Sets Standard Variable 4 for the standard.

Character length is maximum 30 characters. Characters over that amount are truncated.

stdspc.storestd()

In this example, you load all information for a specified standard and then create a new standard with a different name. This allows for easy copying of standards.

Inserts or updates the current part number and all associated properties in the GainSeeker database. Returns True if the store is successful. Otherwise returns False.

stdspc.subgroupsize

Gets/Sets the subgroup size for the standard. Values between 1 and 72 are valid.
