NOTE: after protect program, if i enter incorrect password 4 times, plc is locked. ok. but i downloaded empty project and restart system, it has given me 4 new attach chance.. if someone who wants to steal program, is lucky he can unlock it (in 65536/4 times )

After clearing the memory You have the original project then you can download it again. But the stealer doesn't have the original project If he clear the program memory he can us the CPU but not your deleted program. If you loss your data in your computer you have to reprogramming the plc. That why it is not recommending to set password.

AR10.01 is a code to the PLC when placed at the first step of the program to signal that the next step is a system routine. It does not actually access word AR10.

Edited by Jay Anthony for further review Edited by chakorules: This Link was reviewed by chakorules + Jay we will not allow this kind of post: Software programs that are marketed for such intentions for illegal activities can not be endorsed by MrPLC.com. This link was marketing a software program that could do such illegal activities. Whether or not this software would be used in such a fashion is not for MrPLC.com to be discretionary. We support a free web and welcome your ideas and generally will stand behind your posts. Other posts have been posted recommending software that was NOT marketed and sold as the sole tool for cracking passwords. The main function of the “other” software was to monitor RS-232 data. This kind of post was allowed because the software was not designed to crack passwords, only to monitor RS-232. It just so happens that the RS-232 data packets could be monitored with a monitoring software package and the password could be observed in plain text. I hope you can understand and respect our decisions. We welcome you back to post more information but please refrain from posting links that advertise a product that was designed, marketed, and sold as a product with it's SOLE intent to crack passwords on PLCs. This means if the product is advertised to crack passwords, then it’s not allowed. Also please see our TOS: Point #7 http://www.mrplc.com/tos.shtml 7.
