You can download the one?They want to re-program those blocks but it was locked by the man who'd done the setup.
From the people working in that department, I came to know that they were trying to call that man (someone from Italy) right here but he's not coming. Actually, what he'd done was that he'd locked some of the blocks and deleted the source file. And Siemens didn't provide any feature to unlock.Department people also told me that even the people working in Siemens don't know how to do it. Being a software engineer I know that any thing can be reverse engineered.
So I took up the challenge. How did I unlocked the blocks? The first thing I'd done was searched about this software at Google and read about what is this software all about.
It means a small program that can generate an activation code, serial number, license code or registration number for a piece of software. A keygen is made available by crack groups free to download. If you search a site for S7 Canopener Keygen, you may see the word 'keygen' in the results which usually means your download includes a keygen. Admin No Comments on S7 Can Opener Keygen Download The S7-Tools site is created by a group of experienced Step7 users. We want to make this site a collection of S7 related articles and handy links.
After that I'd explored the software.A person (might be S7 programmer) told me about 'Generate source' and shown me a sample by doing it. Further on he'd shown me how do they lock a block via KNOWHOWPROTECT. It was amazing, they just write this line ( KNOWHOWPROTECT) inside a program after begin statement and compile the code.The compiled code is known as blocks.
The blocks are now protected which means the code inside the block can't be seen by other. Then delete the source and your blocks are now protected. Now my objective was to unlock those blocks.
So I'd followed the steps given below to unlock those blocks, Step 1: Download.dbf file editor. The free DOS based dbf editor is the one I'd used.You can download it from, Step 2: Extract dbfedit.exe from the zipped file. Put it somewhere to easily access it.I'd put it inside a folder named dbfedit in C: drive. So path to run the editor is C: DBFEDITdbfedit.exe Step 3: To unlock the blocks, copy a file named SUBBLK.DBF from. PROJECT ombstx offline 00000001 folder where PROJECT is the directory containing your S7 Project. Paste this file inside C: DBFEDIT folder.
Step 4: Open Command Prompt (DOS window) via clicking on Start → Run → type 'cmd' → press enter or Start → All Programs → Accessories → Command Prompt Step 5: Follow these commands, C: cd dbfedit C: DBFEDITdbfedit.exe subblk.dbf A DOS based application will open. Search for the PASSWORD column.And change all 3 into 0 to unlock the blocks. Press Esc/F10 key to save and exit. C: DBFEDITexit Step 6: Copy the SUBBLK.DBF file inside C: DBFEDIT folder and paste it at it's original location. Always remember to make the backup of original SUBBLK.DBF. Step 7: Now open the project in SIMATEC Step 7 software.All the blocks are unlocked. So my objective is completed successfully.
It took me around 3 hours to complete this for the first time. But after that I can do it within 5 minutes.The automation software house will be no longer in business? Cable And Wireless Cwt2100 Manual Dexterity. So, why should I put my hi-tech machinery in jeopardy?Your machinery supplier or system integrator does no longer support the software they developed and you are in trouble with S7 PLC programs where some blocks say 'block is protected'?
You lost your source code and you cannot access your compiled blocks anymore?You like to keep just one copy of your blocks instead of maintaining both compiled and source copy of each block? You like to toggle the knowhowprotect keyword on-the-fly, without having to compile your blocks? If you find yourself in one of these situations, the S7CanOpener can solve your problem!S7CanOpener FAQs Q: What's the S7CanOpener purpose? A: the S7CanOpener can unlock S7 blocks protected with the 'knowhowprotect' keyword.Q: Can it unlock also S7 libraries? A: Yes, it works on S7programs (.s7p) and S7libraries (.s7l) Q: Can it unlock Step7 v5.5 new “Block Privacy” protection? A: No, at the moment the tool is not able to decrypt such protection. Q: I have a PLC that requires a password for online operations, can I use the S7CanOpener to defeat the password?
The S7CanOpener operates on projects stored on the hard disk, it does not operate online in the PLC memory and does not remove the password set in the CPU at hardware configuration level.Q: Will I be able to read the comments within an unlocked block? A: Yes, if the original block contained comments.
Q: I have some SCL or CFC blocks, can I reverse the code to obtain the source file? In case you have SCL, CFC, GRAPH7, HIGRAPH blocks, once unlocking them you will get the compiled version of the block or, in other words, plain STL code with no comments and no variables name at all.If you expected the full-source text file, it is not possible: in that case your only chance is to get the original SCL or CFC source file.
On the other hand, if you are however interested in the blocks' contents, you have a way to peep into the STL version of the code. Q: Can I lock/unlock UDTs?
A: Yes, from version v1.4 you can lock also UDT (User Data Type) blocks. Unlike all other blocks (OB, FC,FB), a protected UDT cannot be modified but its contents can be displayed. Q: Can I unlock SFCs and SFBs? A: SFCs and SFBs cannot be unlocked since they are functions stored in the PLC's system memory and cannot be read.What we see and use in S7 is just the block's interface (parameters assignment) and not the complete block. Rapidshare Sia Breathe Me. Offline SFCs and SFBs contain no S7 code.
