sIEMENS s7 STRING cONVERSION

[Rheinhardt]

Hi All,
I'm currently busy on a project where i must take a number of char type objects and convert them to a decimal number for comparison reasons.

i tried the standars Step 7 STRNG to INT conversion with no good values.

I understand the string concept like followoing.
Variable type STRING[5]
STRING[ABCDE]

byte 0 Max No of Char
byte 1 Actual amount in String
byte 2 A
byte 3 B
byte 4 C
byte 5 D
byte 6 E

Is there any tip or trick to getting this conversion going
I would really appreciate any help.

If there are any requests i'll post my code on this topic.

Kind Regards

Rheinhardt

Can you just subtract 48 from the data and multiply?

For example the string you are receivinge is "1234"
So you would take byte 1 "1" (ASCII 49) - 48 = 1 x 1000
then add byte 2 "2" (ASCII 50) - 48 = 2 x 100

and so forth.

Is this an ST program?
