Identifier
of Int type - return code: the action success (optional parameter).
bRecalcStat_Bool
in
Identifier of
Bool type - enable/disable the
calculation of related statistical historical values (optional parameter).
Description
The action modifies (or store a new) a value into the for the archive
object
archIdent. The value is given by the identifier valueIdent.
Time of its storing into the database is the time when the value valueIdent
occurred. I the identifier retIdent_Int is not stated, the action doesn't wait for the storing
confirmation. If the identifier is stated, gains one of the following values:
_ERR_TRANS_ABORT
_ERR_TRANS_ERROR
_ERR_TRANS_IGNORED
_ERR_NO_ERROR
Note
If the identifier
retIdent_Int is not stated, there is no feedback to detect the action
success. Action execution time is short, because it is only a request that
is sent to system.
If the identifier is stated, the script waits for the
physical storing of a value into the archive database.
Result:
If I use the action to store a value into the archive without waiting and
then I want to read this value, the read value almost certainly is not this
one, I was stored in the action.
Calculation of related statistical
historical values can be disabled by setting the parameter bRecalcStat_Bool
to the value of @FALSE.
Example
Storing a value into the archive:
REAL _archVal
TIME _archTime
INT _retCode
; archiving time
_archTime := %StrToTime("12:0:0 1-12-2000")
; prepare a value together with time
_archVal := 1 TIME _archTime
; storing into the archive
UPDATEARCHVAL _archVal, H.Int, _retCode
; action success test
IF _retCode # _ERR_NO_ERROR THEN
; error at storing
ENDIF
