CANopen communication with EL6751 module (Looking for example)

I am looking for some project with CANopen communication. In our machine we need to communicate with product (supply module). I create some CAN peripheral objects but I am still struggling with some issues:

1. It throws an event "CAN master reports 2 nodes are configured in OES, but 0 nodes in TwinCAT".
   

   

2. In my OOD the interface i set to "CANopen" but the created peripherals in TwinCAT are inicialized in PeripheralRoot > OnInitHierarchy instead of CANMaster > OnInitHierarchy.
3. I do not know, how to set the Master in TwinCAT correctly.
   

   

Is there someone with a CAN project at your plant? Could you provide me your project or help me?

I already wrote to Nexeed Helpdesk, but I am also trying this way.
