The function suppresses writing values of specified object of
Historical value type into the archive database and leaves original values.
Declaration
%ARC_Nowrite()
Parameters
None.
Description
Use of the function is meaningful only for historical values evaluated periodically (archiving method
Periodical). If a value of such historical value is determined
by the function %ARC_Nowrite(), the value will not be written into the archive database and the function will leave
original value.
For historical values evaluated on change (archiving method
On value change), the function behaves like the the function
%ARC_Unwrite.
