 PLC password protection can be removed by removing the Battery and remove the power for some specific time.In most of the cases the protection removed, if the protection still present then remove the processor (in PLCs where  Controller connection to base board through the FPGA slot) for some time.

By means of logo ctrl panel-without entering the menue-clear prg. or with wrong password (entering the menue with wrong pass word). By means of program Module-card-copying data from program module will not perform password check. and by the soft comefortv7-to continue using the program without password copy all existing block and insert them in the new project. password will not be copied along (delete program through tools.).
