This article introduces several methods for encrypting and decrypting Omron plc using programming software and programmers, including programming software to operate CX-P, SSS, CPT encryption methods and encryption and decryption methods for programmer operations.
Programming software to operate CX-P, SSS, CPT encryption methods
CPT encryption method: Online—Password Protection—Active
CPT decryption method: Online—Password Protection-- Release
SSS encryption method: use the combination key CTRL+O, F1 connection, END, select the transfer program, then select the “PC-computer” screen, hold down SHIFT+F10, input the PLC password, confirm, the computer automatically transmits the program, etc. After the program is transferred, use the combination key CTRL+O again. After F1 is connected, enter the password and confirm.
CX-P encryption: Add a programming language to the front of the written program:
--ll-- FUN (49)
AR1001 000 000 # ABCD
The number is a 4-digit hexadecimal user password. After the program is transferred to the PLC, the second power-on takes effect.
Use the programmer to encrypt the OMRON plc encryption and decryption method: CLR-MONTR-CLR until the screen appears 0000, press LD-SHIFT-HR1001-
FUN(49)-WRITE(0000)-WRITE(0000)-WRITE-#ABCD(password to be added)-WRITE
Decryption: After plugging in the programmer, press CLR-MONTR-CLR-SHIFT-CLR-RESET- to appear? ? ? ?
(Prompt for password) ABCD-WRITE
This article is about changing or changing the PLC password when you have mastered the password or if the password is not set in the PLC.
