Continuum object editor crashes when applying changes to a BACnet object in a third party device.

Issue

When changes are made to the BACnet schedule in a third party device, the object editor crashes when the changes are applied.

ACCTrace file shows the following error:

The datatype of a BACnet property value specified in a service parameter does not match the datatype of the property referenced by the specified Property_Identifier.

Product Line

Andover Continuum

Environment

CyberStation

Continuum

BACnet

Trane SC Schedule Object

Cause

The object type is not fully support by the third party controller.   Consult the devices PICS statement.

Resolution

In some cases third party vendors will implement BACnet object types for internal use while not allowing other vendors to write to these object. 

Occasionally it may be possible to write values to some of the objects properties.  However, when Continuum tries to write to a value to the unsupported property the object error will crash.
