Hello everyone. I got a step7 bolck, it can work in the PLC, and you can see " size in work memory" is bigger than empty block, but when you open the block, the content is empty!
there is not any program in it.
it is programmed by STL language.
Are there anybody konw how to see the logic in the block, or how to crack it?
Thanks in advance!
Block screen shot is below,

Re: [?]: A Step7 block can't see the content ?!
open it with pg2000
viewtopic.php?f=9&t=5614&p=55070&hilit= ... .69#p55070
PG2000 v4.69 with crack Link_is_Dead :(/PG ... _crack.rar
This is bug "BLD-protection"
Replace all "BLD *" to "NOP 0" in PG2000 or S7-Doctor
or
use WinHex
open file <Project>\ombstx\offline\00000001\SUBBLK.DBT (*Number possible 1/2/3/ ...9)
Find and replace 10h 07h (BLD 7 = 0x10 0x07) to 00 00 (NOP 0 = 0x00 0x00)
2. delete # before Mxx (for example JC #M001)
open fc in pg2000,select all, copy to notepad, delete # before Mxx (for example JC #M001),
delete : before operands (for example :A DBX0.1),select all, copy to anover FC, replace fc calling for check

cured codeЧтобы увидеть "скрытую" часть можно сделать так:
1) чтобы убедится, что используется такая "защита", надо открыть проект в какой нибудь не сименсовской программе (например S7-Doctor)
2) Для открытия и работы в Степе с этим проектом: шестнадцатеричным редактором заменим код команды BLD 7 (0x10 0x07) на код команды NOP 0 (0x00 0x00) в файле
<Папка проекта>\ombstx\offline\00000001\SUBBLK.DBT (вместо "00000001" может быть другая папка)
и при открытии в Степе увидим (FC1 из проекта "PROTECT"):
Code: Select all
NOP 0 // replaced "BLD 7"

Re: [?+]: A Step7 block can't see the content ?!
I can open the program now.
Thanks you very very much!
I have one more question, do you know how can they do it (suppress displaying content) in step7 ?
I have tried the way you provided, but I meet some difficulties.
1. When I change the program by PG2000 (replace all BLD * to NOP 0) and save it by PG2000, I can't open the program in step7 again. Maybe two softwares (Step7 and PG2000) have different program format?
2. Then I change the program by Hexedit (replace all BLD * to NOP 0), this time step7 can open the program but I can't see the program content either.
3. How can I change "#" of jump lable "#M***" by Hexedit?
I can't delete "#" in PG2000, when I do this, an error occur and I can't save the changed program.
I want to know what the mean of delete "#" ?
After I change "BLD*" to "NOP 0" in PG2000 and save the program. When I open the modified program in step7 (V5.5.2) the warning message is below,
"The project or library was changed using tools of the Windows Explorer. The data for access protection has been modified to such an extent that it is no longer possible to open the project or library."
