Control Limit Event

Sepasoft MES Module Suite

Control Limit Events

The event is executed to calculate a control limit value. Whenever control limits are calculated, the script in the associated control limit is executed. All control limit events have getData() function to return the SPC data.

Example

The following code snippet logs the column names of the dataset returned by Individual LCL control limit.

Python

ds = event.getData()
logger = system.util.getLogger('Individual LCL')
#logs column names to the gateway console
logger.info(str(ds.getColumnNames()))

[Date Time, Measurement 1, XBar, XDBar, MR, MRBar, Individual LCL, Individual UCL, SampleUUID, Note, Cause]

System is set to use up to 6 decimal point places for Control Limit Values: When calculating control limits the system uses the Attribute Property format property to determine how to display the limit value (i.e., how many digits after the decimal to use if the control limit calculated value is of a decimal value)

Column Names Corresponding to Control Limits

Column names of the dataset returned by event.getData() corresponding to each chart is given below.
