(Process)
• Only the SIL2 Process CPU and Safety CPU support the user authentication function.
This function serves to protect the user property stored in a personal computer and the user property inside modules in the
MELSEC iQ-R series system against threats such as theft, tampering, faulty operation, and unauthorized execution due to the
unauthorized access by an outsider. Use an appropriate security function according to the purpose as shown in the following
table:
