Failed to create object of PLC Composite type in Control Structure - Compact HMI 6.0.1

Dear all,

I am running 800xA Compact HMI 6.0.1 and I have come across an issue when importing some of the object types from 800xA DCS system. When I create PLC Composite Process Object Type in Compact HMI and this type consists of another PLC Composite type then I get error when instantiating this object in Control Structure.

Failed to create object!


Aspect failed to unserialize itself

Everything is fine for simple objects which doesn't consist another type.

Is it related to Compact HMI installation that only simple types are allowed?

Thank you.

PLC ProcessObjectConfiguration Aspect logs are created in “C:\Program Files(x86)\ABB industrial IT\Operate IT\Common\Data\LogFiles” .  

But if PPA is launched WITHOUT Administrative Privileges, it restricts access to this (“C:\Program Files(x86)”) folder and the program exits during the process when it tries to write to the log and fails to complete the “UnSerialize” operation .  

Thus, we get the error “Failed to create object! E_AFW_AOM_ASPECT_FAILED_TO_UNSERIALIZE(0x8Abb0947)”.  

This restriction to the “C:\Program Files(x86)” folder would be from the PPA side. 



Launch PPA with administrative privileges (right click on the Workplace icon and select Run as Administrator) and then create the instance of two level composite objects.
