Display Priority of the Objects
Objects that can be presented on the C7-613 can interrupt each other. Only
objects with a higher display priority can interrupt objects with a lower display
priority. Objects are listed below according to their display priority:
•
System messages (highest display priority)
•
Error messages
•
Info texts
•
Process screens, standard/special screens
Operational messages cannot interrupt objects. They are presented only in the
message level.
It is not possible to select a process screen/special screen at the time an object
with a higher display priority is being displayed (“HMI API” FB, RETVAL = 880B).
Repeat the request when the higher priority object is no longer displayed. Use the
“OBJ_TYPE” parameter on the “HMI API” FB to obtain the type of the object that is
currently being displayed (refer to Section 4.5).
