Hi All,
I have issue with WinCC data entry field if somebody can help me with. There are few set points to be written to PLC from the Simatic multipanel HMI. I am using WinCC flex Advance to configure this HMI.
Whenever an operator enters the setpoint from the HMI, HMI should check the limit on the Setpoint tag, if the value entered exceeds the limits on the tag then it should not allow that data entry and should show previously entered value.
I tried to implement this but what is happening just now is, HMI is not passing the exceeded value to the PLC but it is holding exceeded value in the field on the dispaly so operator could be mislead that the value has been through to PLC. The value only returns to the previous value when you navigate to different screen and come back again on same screeen.
I appreciate all the help.
