Note:
Using the patch function is only possible with information
about the structure of the internal data memory; therefore, this
function can be used effectively only by the developers of the
IndraDrive firmware.
In order to record internal signals (memory address contents),
P-0-0485,
Patch function 1, display
or
P-0-0491, Patch function 2, display
have
to be configured in one of the signal selection parameters (P-0-0023,
P-0-0024, P-0-0147, P-0-0148).
Note:
The patch function has to be parameterized before the
assignment as trigger or measuring signal.

chapter
Activating the Oscilloscope Function
The oscilloscope function is activated/deactivated by means of parameter
P-0-0028, Oscilloscope: control word
.
P-0-0028, bit 0:
•
bit 0 = 1
→
starting a measurement
•
bit 0 = 0
→
stopping a measurement
By setting bit 0 in P-0-0028 the oscilloscope function is activated, i.e. the
recording of measured values of the selected signal starts. The
oscilloscope function waits for the selected trigger edge or level to occur.
At detection of a valid edge the measured values keep being written to the
measured value memory until the number of measured values defined in
parameter
P-0-0033, Oscilloscope: number of measured values after
trigger event
has been reached (delay function).
After the defined number of measured values has been recorded, the bit
"delay function completed" (bit
4) is set in parameter
P-0-0029,
Oscilloscope: status word
. The recording is complete and automatically
terminated. Bit 0 in parameter P-0-0028 is reset and the list of measured
values can be read.
Note:
Depending on the parameterization of the size of memory, the
time resolution, the number of measured values after trigger
event and the point of time the trigger event occurs, the entire
measured value memory for the current measurement is not
always written.
This means that there may still be old measured values in the
memory that are not valid for the current measurement!
Trigger Function
The drive provides extensive and flexible possibilities of triggering.
Trigger Signal Selection
The trigger signal is selected in parameter
P-0-0026, Oscilloscope:
trigger signal selection
by directly inputting parameter IDNs. Only such
IDNs are allowed that are contained in the list
P-0-0149, Oscilloscope:
signal selection list
.
