Hi, in order to edit and insert data via HMI, you need to define a variable and set it to be a Keypad Entry.

For more information see the Help file in U90 Ladder >> HMI >> Variable >> Keypad Entry Values.

If you want to store values in the database:

1. Use SI 40 Database Index to access a particular MI.
   For example, to access MI 2 you store the number 2 into SI 40.

1. Use SI 41 Database Value to write a value into MI 2.
   For example, you can store a number value into SI 41.

For more information see Help >> Utilities >> Using the database.
