            Description

            When the controller stack is switched to bus off and back to bus on, the firmware may send old or wrong process data to devices after re-establishing the connection. The problem might occur whenever the controller starts establishing connections after:

            • Configure or reconfigure controller while using application controlled startup (This includes ChannelInit to load database)
            • Switch bus state to bus on via packet or DPM

            The problem might be hidden, if application manages to write DPM Output area at least three times before a connection is established.
