Which products are affected?
ESP-HMI1-P (HMI Designer V1.7)
What happens?
'Automatic operations' which activate a page changeover are no longer executed. 'Automatic operations' are only executed again after mains switching of the keypad.
When does the problem occur?
If a page is changed by an 'Automatic operation' while the user presses a function key/touch key by using the Momentarily set bit function or Momentarily reset bit function, this 'Automatic operation' is no longer executed afterwards.
Possible diagnostics?
None.
Short-term measures/recommendations?
Generate your HMI project in such a way that it is ensured that a page is not changed by an 'Automatic operation' while the user executes the Momentarily set bit function or Momentarily reset bit function.
Evaluation:
Among other things 'Automatic operations' are used to activate page changes, e.g. in order to be able to change automatically to the diagnostics page if a drive trips. If the user presses the function key/touch key assigned with the function Momentarily set bit or Momentarily reset bit at that moment, the 'Automatic operation' blocks and is only executed again after mains switching of the keypad.
