Schematic diagram of the receive sequence
TX_CNT_ACK 0-3 The value TX_CNT_ACK is a copy of the value TX_CNT. The value
TX_CNT was transferred together with the last data segment of the
process output data.
The value TX_CNT_ACK is a confirmation of successful acceptance of
the data segment using TX_CNT.
RX_CNT 0-3 This value is transferred together with every data segment. The
RX_CNT values are sequential:
0001101100…
(decimal: 01230…)
Errors in this sequence show the loss of data segments.
RX_BYTE_CNT 0-7 Number of the valid bytes in this data segment.
TXBufNotEmpty 0-1 This bit signalizes that the transmit buffer still contains data.
It is automatically reset when the last character is sent.
The bit can be used as control bit for actively triggering the sending of
the TX data buffer.
BufOvfl; FrameErr; Hnd-
ShErr; HwFailure; PrmErr
0 - 255 Diagnostic information (correspond to the diagnostic information in
the diagnosis telegram).
These diagnostics are always displayed and independent to the setting
of the parameter „Diagnostics”.
