Retrieving Test Data by Time Frame
You can retrieve test values for one or more variables during a specific time period. You can filter on a specific product, if you wish, as well as select a specific crew and shift. Multiple variables are returned with timestamps. Refer to the GE Intelligent support site for examples in the Knowledge Base.
If you select more than one variable, only the captured values of first variable will correspond directly to the time stamp. The captured test values for the remaining variables will simply be the first values that match the output range limit and that fall within the specified time. For example, if you select two variables (A and B), a time range of one month, and your output range allows for 12 columns of time stamps. You will get 12 captured values for Variable A that correspond to the 12 time stamps. However, the captured values for the remaining variable (B) will be only the captured values that occurred between the start time and the end time; they will not correspond with the 12 time stamps. This means that you might have anywhere from zero to 12 variables, depending on the test frequency of the second variable.
Before you retrieve test data, you’ll need to have the Variable ID(s) or Variable Description(s) on your worksheet. For more information see Searching for Variables.
