            Description

            Sometimes after a System start reset reading or writing of process data using driver functions fails with error 0x800C0022 (I/O data exchange failed). After next reset data exchange may be functional again.
            There was no data exchange while reset was executed. After reset the command and acknowledge flags in communication registers are different.
