            Description

            When DMA Operation is enabled and the Profinet Controller Firmware is configured to use Provider IOPS, an invalid length for the DMA Transfer is calculated. As a result, the DPM Input Area might be overwritten with values from Host memory by the Output DMA Transfer. As a result invalid input process data might be passed to the host application.
