Posted 4 Oct 2018 Hi. Is it possible set an I/O Field, in input or input/output mode, to not pop up the on-screen input keypad? Most of the time the keypad is useful, but in this case I want the machine operator to use function keys instead to increment/decrement motor RPM values during runtime. I'm using an S7-1200 PLC & KTP400 Basic HMI. Thanks in advance. Regards, Dale Share this post Link to post Share on other sites
Posted 22 Oct 2018 just set the field property as output and then modify the value using keymap actions Share this post Link to post Share on other sites
Posted 25 Oct 2018 You're right, I can use Function keys to modify I/O field values in Output mode, but there's a problem. This HMI (KTP400 Color) screen contains several I/O fields. In Input/Output or Input mode, the operator can select one of them by tapping the screen, but then the on-screen keyboard pops up. In Output mode though, there's no way for the operator to select which I/O field to modify because in Output mode they can't receive focus by tapping the touch screen. What I would like is for the operator to be able to select one of several I/O fields by tapping it, and then not have the on-screen keyboard pop up -- instead modify the field value up/down using a couple of Function keys. Is this possible? Thanks, Dale Share this post Link to post Share on other sites
Posted 25 Oct 2018 I haven't used that PLC/HMI before, but I have used WinCC Flexible/Comfort and S7-series PLCs. Do you have access to the PLC to modify code there? If so, you can use a numeric display with a button next to it or use a button with the numeric display superimposed on it. In the AB world, you can embed the numeric value inside the button caption itself but I don't know if you can do that in the Siemens world. The button would control a tag in the PLC that selects which number the function keys will increment/decrement. You can probably use a rectangle behind the button or an indicator/animation tag on the button to highlight the one that's selected. Share this post Link to post Share on other sites
