    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.

    As an example, you can use the peripherals from the reposetory NexeedCanHde6 or NexeedCanHupe.

    I already solved point 2 with help of BCI colleague. The solution was to add base type OpconCoSlave to CodeEntities.osd.

     

    <?xml version="1.0" encoding="utf-8"?>
    <OpconStdDefinition def="1.0">
      <TypesDef def="1.0">
        <CodeEntity name="CanRbDnox8SupplyModuleTx" baseType="OpconCoSlave">
        </CodeEntity>
      </TypesDef>
    </OpconStdDefinition>
