This is how far I’ve got know :

OPN DB48 //Open DB48 were I get my number
L DBW 6
T MW 10

OPN DB 1 //Here are the different possibilities
NEXT:L DBW [MD 50] //The pointer that I use, I initialized it in OB100
L MW 10

<>I //if accu1 is different from accu2 then
L P#2.0 //increase the pointer to load the next value
+D
T MD 50
JC NEXT

O
==I // if accu1 = accu2
= Q 0.7

I do this in FB1 and i Jump to FB1 (from OB1) each time there is a new number.

Can somebody tell me what I do wrong because the PLC is always going in stop mode.

Hello,

Thanks for the reply I shall try out your program, but in the mean time I have found something else with some help.

This is it :

OPN "Data"
L DBD 4
T MD 10

OPN DB 1
next: L DBD [MD 50]
L MD 10
==D
JC volg

L P#16.0
L MD 50
<>D
JC val

L P#0.0
T MD 50
R Q 0.7
R M 3.0
JU eind

val: L MD 50
L P#4.0
+D
T MD 50
JU next

volg:= Q 0.7
S M 3.0
eind: L P#0.0
T MD 50

As you can see Iused DWORD because the numbers that I have to compare are also DWORDS

Kind regards Jasper

Hello simaticus,

So a pointer must always be DWORD that's something I learned today, I always use DWORD but the only reason was that the software didn't take any other possibilities.

But asI mentioned beforeI have to get a number from another DB and these numbers are 1 BYTE (e.g. B#16#EF).
When i use a pointer (DWORD) he gets the first4 Bytes, but I only need the first byte.

Maybe you've got a solution
