Function description:
|
|
|
|
This modul handel's the the tracing on the K-Line and on CAN.
|
|
You can start the tracing with TRACE_MODE=T_ON. The Prüfliste is going on.
|
|
You can stop the tracing and read back the traced data with TRACE_MODE=READ.
|
|
Tracing on CAN:
|
|
It is possible to trace all date received on a defined CAN-ID. All
|
|
traced data are stored in a file hold on the SKM.
|
|
It is possible to trace more then one ID. But the traced Data are hold
|
|
in different files/buffers, one for each CAN-ID.
|
|
In a second step you can read back the data from SKM and store in a
|
|
array.
|
|
Tracing on K-Line:
|
|
It is possible to trace all received Bytes on the K-Line. It is not
|
|
possible to send parallel to the tacing data to the ECU over the k-line.
|
|
|
|
Parameter discription :
|
|
|
|
Inputparameter:</pre><b><a name="param1">1</a> FILENAME:</b><pre> It means the filename used in the SKM for storing the traced
|
|
data. (maxlen = 80 Char.)</pre><b><a name="param2">2</a> FILESIZE:</b><pre> Size of the file in Byte. (0...100000)
|
|
If the number of the traced data reach the filesize, the
|
|
tracing will be stopped.</pre><b><a name="param3">3</a> TR_INTERFACE:</b><pre>Type of communication-line.
|
|
CAN = tracing on CAN
|
|
K = tracing on K-Line</pre><b><a name="param4">4</a> TRACE_MODE:</b><pre> T_ON = switch on tracing all received data.
|
|
This module is leave after setting up the job.
|
|
If you want to trace 5 Seconds, you have to insert
|
|
a waitingtime for 5 seconds after this module.
|
|
READ= Switch off tracing and read data from file <FILENAME>.
|
|
All data are transfered from the SKM-File to the array in
|
|
<RETURNARRAY>
|
|
ATTENTION: If you want to read data, the Inputparameter must be the
|
|
same as in TRACE_MODE=T_ON, because the buffername is build in dependence
|
|
of the Inputparameter.</pre><b><a name="param5">5</a> CAN_ID:</b><pre> Read-Identifier on CAN-bus which should be traced.</pre><b><a name="param6">6</a> CAN_IDLEN:</b><pre> [11,29] 11/29 bit identifier.</pre><b><a name="param7">7</a> MAXTIME:</b><pre> Maximal time to trace. [ms]
|
|
Is this time up, the trace will be end.
|
|
|
|
Returnparameter:</pre><b><a name="param8">8</a> RETURNARRAY:</b><pre> The return parameter from the SKM are stored here, if
|
|
MODE=READ_DATA.</pre><b><a name="param9">9</a> ERROR:</b><pre> != 0 if an error has occured.
