Handling unknown and missing device objects
If the plug-in connects to the device, it receives the device description from the device. It may be the
case that the device description in the plug-in is different to the one in the device.
The following cases can occur:
–
Unknown device object
–
Missing device object
–
Inconsistent device object
The following displays are possible depending on the view:
–
Display in graphical view.
The parameter panel cannot be used if a parameter, that is absolutely necessary for the graphical
display, is not included in the device description transferred from the device or is defined incon-
sistently.
A corresponding message is displayed.
–
Display in tabular view.
The cases in the tabular display are depicted in colour as follows:
