Diagnostic information (correspond to the diagnostic informa-
tion in the diagnosis telegram).
These diagnostics are always displayed and independent to the
setting of the parameter "Diagnostics".
STAT
0-1
1: The communication with the data terminal equipment (DTE)
is error free
0: The communication with the data terminal equipment (DTE)
is disturbed. A diagnosis message is generated if the parameter
"Diagnostics" is set to "0/ release". The diagnostic data show the
cause of the communication disturbance.
The user has to set back this bit in the process output data by
using STATRES.
TX_CNT_ACK
0-3
The value TX_CNT_ACK is a copy of the value TX_CNT. TX_CNT
has been transmitted together with the last data segment of
the process output data.
TX_CNT_ACK is an acknowledge for the successful transmis-
sion of the data segment with TX_CNT.
RX_CNT
0-3
This value is transferred together with every data segment.
The RX_CNT values are sequential:
00->01->10->11->00...
(decimal: 0->1->2->3->0...)
Errors in this sequence show the loss of data segments.
RX_BYTE_CNT
0-7
Number of the valid bytes in this data segment.
