Posted 12 Nov 2010 Hi Guys! I have a concern. I saw someone unlocking a CJ PLC using a console. I asked how did he do it but he said only Omron guys should know it. I have read about the forum on unlocking a PLC using CF card but obviously it will not work if the programmer prohibits saving from a memory card. Hope someone could share how to use the console to unlock PLC. Thank you, Isidro Share this post Link to post Share on other sites
Posted 12 Nov 2010 If only the Omron guys are supposed to know it, then it is a backdoor they can use in an emergency to help their customers, and not information which they will share with the public. I know a decade ago if a CPU needed to be unlocked and the password was not known, the only way was to format the CPU and lose the program, or send the CPU to Japan where they could unlock it.
