Hi, I'm new here, and first want to thanks you people for share the tools to our work. In return I wanto to share my private solution for this problem and for all the rslogix 500 compatibles plcs (tested for real with micrologix 1100,1200,1400 Serial and ethernet comms).

Now it's simple, after some hours debugging the rslogix I found some interesting things inside this software. Number 1: You can just patch some bytes and bypass the password check to upload(plc->pc) a program. (My patch is for RSLogix 500 Version 8.10.00 (CPR 9) Build 18 [CRC32='67AF5288'] Patch the file rs500.exe Offset Old Byte New Byte ---------------------------------------- 00313C64 74 90 00313C65 14 90 ----------------------------------------- We replace some instruction by nops and it's done. Save this file with a new name like, rs500_nopw.exe and try. If a had some more time I'll try to port this patch to other versions of RSLogix. Number 2: I also found a master password that I use to clear the protection.

Go to the 'Controller Properties' >'Passwords'. PW 22865625 (erase any password). If you just want to check if this method works, try to clear your own project's password with this number. Thank everyon again. (Sorry for my bad english, isn't my native language). Patch the file rs500.exe Offset Old Byte New Byte ---------------------------------------- 00313C64 74 90 00313C65 14 90 ----------------------------------------- ******* Great Work! I have RS500 version 7.30.10 and I copied the executable to a separate folder, opened it with my hex editor.

Important: When a valid activation cannot be located by the software, the software will enter a seven-day activation grace period, during which you will be able to run the software with full functionality. If this seven-day grace period ends before a valid activation has been found, you will no longer be able to start the RSLogix.

The line of code in this version for the bytes you mention above are as follows: Offset: 00313C64 = 89 Offset: 00313C65 = 4D I'm not sure if the password ignore parameter is a this byte address, and what the new values should be. I am dealing with a dead beat OEM and our only option is build new equipment, but we really would like to start with the old code if possible. The code is in a Micrologix 1500. Thanks for any advice, Mark Monitor *******.

NOPing is changing an Assembly command from what it was to having no operation. So, that is what changing the 74 14 to 90 90 really means. 74 14 is a Jump equals short to a different address in the program after a test eax,eax is bening completed. I just gave version 9.05.00 (CPR 9) a quick once over, but I don't have a micrologix or any SLC 500 processor to test anything on right now.
