Online Security
Online security refers to limiting the ability to read data from the Machine Controller.
You can set security key (i.e., a password) and privilege levels for programs to restrict the ability
to read the program data from the Machine Controller or to open the programs to users who
have at least the specified level of file reading privilege.
