    That is not a problem, it's the intended behavior. Any node receiving a consistent frame shall acknowledge it. Inconsistent frames shall be flagged with an error frame. Check the CAN specification.

    CAN has no concept of a fixed master/slave relationship, and there is no such thing as a CAN address. You might be using the CAN protocol in a way it wasn't designed for.

    Hi,

    I have a problem with the CAN interface. I an building a CAN controled network with one master and 5 slave units. Each slave has an individual filter address ( 1 to 5). At the moment I am testing the system with one master and one slave. The problem is that the slave generates an acknowledge signal even though the data package is addressed for another CAN address. Anyone have an idea what could be the problem?
