Overview
Operating touch objects
Touch objects represent touch-sensitive operator control objects on the HMI device screen
such as buttons, IO fields and alarm windows. Touch objects are basically operated in the
same way as conventional keys. You operate touch objects by touching them with your
finger.
The project may contain operations which require in-depth, device-specific information from
the operator and must be executed with particular care, for example, simulation of jog mode.
Further information on this may be available in your plant documentation.
CAUTION
Never touch more than one object on the screen. Never touch more than one touch object
at a time, otherwise you may trigger unintentional actions.
CAUTION
Do not use any pointed or sharp objects when operating the touch screen in order to avoid
damage to its plastic screen membrane.
Operation feedback
The HMI device provides optical feedback when it detects the operation of a touch object.
This feedback is independent of any communication with the PLC. Therefore, this feedback
does not indicate whether the relevant action is actually executed or not.
The configuration engineer may also have configured the feedback function in a different
manner. Further information on this may be available in your plant documentation.
Optical feedback
The type of optical feedback depends on the operator control object:
●
Buttons
The HMI device outputs different views of the "Touched" and "Untouched" states,
provided the configuration engineer has configured a 3D effect:
–
"Touched" state:
–
"Untouched" state:
