5.4 Security function (screen protection function)
In the user screen mode, screens can be set so that they only open to certain operators who
know an entry code. This is so that general operators cannot perform unnecessary operations.
This function is called security function (screen protection function).
5.4.1 Outline of security function
To use the security function, the security level should be set for each user screen.
Set the level within the range of 0 (lowest) to 15 (highest). When any entry codes have not
been registered, all screens can be displayed (In this case, the security level is "0".).
An entry code can be set using the screen creation software.
By entering a correct entry code, the user can display and manipulate screens whose
security level is equivalent to or lower than the entered code
