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 =).

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