Applications > Security Control

The Soft-GRAF HMI provides the following ways to ensure the system security.

Designers can set the level value (1 ~9) for a button requires security. If the user’s login level is lower than the button’s level, the
user cannot operate this button. The user’s level is 0 unless successfully login to get the higher level permission (Level 1 ~ 9).

The integer and real input buttons may set up the maximum and minimum value to prevent the operator to input a wrong value
accidentally.

Most of the buttons provide an "Ask before operation" feature which can be used to confirm the user’s operation. You can check
this option to improve the safety.

The Boolean, integer and real input buttons provide an "Identify Password" feature for the strict input control. After checking
this option, operators must input the correct password to use the button.

For those data require security, you can put them together within a particular page and then set a higher level value (1 ~ 9)
for a "g_ToPage" button that is to get into this particular page. So that the user with a lower level cannot enter this page.
