How to input value using PLC keyboard

[Ljuba]

Hi,

How to input value using PLC keyboard?

I have some MI integers that I want to show on Jazz PLC Display, and I want to be able to change them using PLC keyboard. How to do that?

Thanks in advance,

- Make a new Variable with that MI in it.

- Select part of the screen where you want this MI to be displayed, then right click -> Attach Variable

- Input will activate whenever you navigate to that screen. If you want to have input only when you press a certain key (usually enter), you'll need to make a logic that will set SB39 each time you open a new screen, and reload a screen when enter (or whichever key) is pressed. I think there's a topic about this in forum somewhere, maybe even in examples in U90.

See the attached program.

Screen 1  Displays the number - but it cannot be edited

Press the Up Arrow to go to the Next Screen to edit the number

Press Enter 2 times -- 1st  to accept the new number, 2nd to go back to the main display.

Thanks, this is not what I was looking for, but definitely helped me to get to right solution. I didn't realize that PLC automatically, after I select keypad entry in variable list, and select display that has this variable, gets to input value.

I realized that after I downloaded program into PLC.
