6.2 Security Function
The theft, tampering, incorrect operation, and illegal execution of customer assets stored on personal computers, or customer
assets inside modules in the MELSEC iQ-R series system due to unauthorized access by a third party is prevented. Use each
security function for the purposes below.
File password
This function is used to protect the data of Motion CPU by registering a password for the file in the Motion CPU.
Password authentication is required when reading/writing data.
There are two types of password, "Read protect" and "Write protect". Both settings can be specified for a single data item.
