Not sure what it is you need.

Maybe try the block FC85 "FIFO" found in the standard library under TI-S7 Converting blocks.

have half a solution,

A M 0.7
AN M 0.0
JNB _001
CALL "ATT"
DATA :=DB2.DBW0 // measured value word
TABLE:="dw fill".DB_VAR
S M 0.0
_001: A BR
= M 0.1
// ------------------------------------vetelezesi ido
AN M 0.7
L S5T#1S
SD T 1
NOP 0
NOP 0
LC T 1
T DB2.DBW 6
A T 1
= M 0.7
// ------------------------------------
AN M 0.7
R M 0.0
-----------------------------------------------------------
but the new question is how to convert Word Dword because the measured value is Dword

SCl

Do You have SCL ? I luv SCL for such things:::

I RISING EDGE CONDITION THEN
FOR i:= 100 TO 2 DO
ROW := ROW [i-1];
END_FOR;
ROW [1]:= MEASURED VALUE
END_IF;


It shifts the complete table 1 index further and enters the new value in index 1. If the Condition happens every 5 minuts, then you are logging in a FIFO way.

JesperMP his method in stl is also a good way.

Regard,
