TimeEQ (Tag-based PE function)

Find the total time in seconds, within a range, when a point is equal to a given value.

Syntax

TimeEq(tagname, starttime, endtime, value)

Arguments

tagname

A tagname.

starttime

Beginning of the time range to search. Relative times are relative to endtime, if endtime is not itself a relative time.

endtime

End of the time range to search. Relative times are relative to starttime, if starttime is not itself a relative time. This time must be after starttime.

value

Must be an integer or real number or digital state (character string); the value to search for.

Returns

The time period in seconds within the given range, for which the point was exactly equal to the given value.

Example

TimeEq('tag1', 't', '*',40.0)

TimeEq('digitaltag', '-1d', '*',TagVal('digitaltag', '14-Dec-97'))

TimeEq('digitaltag', '14-Dec-97', '*', "On")
