Dear all
i wont to convert this pieace of S5 instruction to S7 which contain LIR1 :

FB234
nom :DASA
Design EQNR E BY

L =EQNR
B MW 196
A DB 0
L DW 9
TAK
< F
BEB
L DW8
: F
T MD 250
L DW6
+F
LIR1

.........

As I Know to convert LIR1 i must have value of accumulateur1 which is the conserned adress so LIR1 is replaced by the value of this adress.
but using only the programm and i know that the plc is related to an old op 3XX ,how can i resolve this problem??

(i think that i have to know the realtime value of (mw196,dw9,dw8,dw6) which is only possible if i am near the PLC????)


thnaks and best regards.
