I am using Quickpanel view plus and have displayed system date and time on a screen
It was working fine until....
i changed the "time" of the hmi using the system tools -> control panel -> clock option.
Now instead of showing date and time , it is showing '??' in both date and time field.
Any pointers to resolve would be appreicated.
regards

?? means that there is no connection to the device or address or that there is some other error with the variable. To display date and time, you can use the internal #CurrentTime variables. Note that internal # variables are hidden by default, right click on the variable list and select Filter by... Unfiltered. You will see variables for year, month, day, hours, minutes, seconds and milliseconds that you can use on your display. Format the text, if using, to allow for sufficent width for the resulting values. Note that QuickPanel View is replaced by QuickPanel+ which has better screens and multi-touch technology for better operator response.
