) according to the methodology based on flags of individual values entering the calculation. The result is a real value. An eval tag must be evaluated on a change (Evaluation method parameter set to On change value). Function evaluation time is rounded to a minute, i.e. seconds and milliseconds = 0.REAL %EcoAve( REAL in Arg, REAL in ValidCriterion, BOOL in ResetTrigger )
Arg | A parameter, average of which is to be calculated. |
ValidCriterion | Validation criterion value [%]. |
Impulse | Change of the parameter into the TRUE state causes evaluating the average, which is to be assigned to the eval tag value. At the same time, input values for the next period of time (Arg) are to be processed. |

Types of flags for Automated measurement systems:
The value is valid if the A flag is not set, i.e. A=FALSE. The operation is stabilized if the B flag is not set, i.e. B=FALSE.
The following validation criteria are applied on CF flags of processed values:
ValidCriterion
(%) of all measurements in a specified time period.ValidCriterion
(%) of all measurements in sa pecified time period.Condition of flags processing:
