To access and program an Omron PLC, users typically employ software tools like CX-One, CX-Programmer, or NJ-Designer. These software packages allow users to create, edit, and upload programs to the PLC. Programming an Omron PLC involves using ladder logic, a graphical representation of the control logic, or function block diagrams.

Prevents the program from being uploaded from the PLC.
For desperate situations: desolder the EEPROM chip (e.g., 24LC256) from the Omron CPU board. Use an EEPROM programmer (like TL866) to read the raw binary. Search for the ASCII or BCD representation of the password. This is and requires expert soldering skills. Once you have the password, you can re-solder the chip or program a new one.
Omron PLCs come equipped with robust security features to prevent unauthorized access and ensure the integrity of the control system. Some of these features include:
