CANopen errors on slave Codesys 3.5, CAA

Got the nodes to show up by ticking off "Enabling diagnosis for devices", restarting the application and rebuilding.

Hello,

I'm trying to make use of the CAA library to detect specific can errors locally on a CANopen slave. On paper this should work:

//Set temp node
IF _itfNode = 0 THEN
    _itfNode := DED.GetRoot();
END_IF

//Iterate till the only CANbus node is found
IF NOT CANbusNodeFound THEN
    _itfBus := DED.INode_TO_IBus(_itfNode);
    //Check if the CANbus has been able to cast
    IF  _itfBus <> 0 THEN
        CANbusNodeFound := TRUE;
    ELSE
        _itfNode := DED.GetNextNode(_itfNode);
    END_IF
ELSE
    GetCANopenBusError( itfNode := _itfRootNode, einBusError => CANopenBusError);
END_IF

But the itfRootNode is null and checking if itfRootNode is root returns FALSE. Confused, I tried to quickly list nodes with

nodes : ARRAY [0..12] OF DED.INODE;

But they're all null. Which is weird since changing the number of nodes before compiling requires an array size change. Has anyone had a similar problem? Using a safety PLC (CR710s) with the standard application selected.

I'd be very thankful for any kind of pointers =).
