bufferVar.extravalues
This attribute contains the additional values in a reading buffer.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (R) Yes Restore configuration
Instrument reset
Power cycle Not applicable Not applicable
Usage
extraValue = bufferVar .extravalues[ N ]
extravalue
The extra values for readings
bufferVar The name of the reading buffer, which may be a default buffer (
defbuffer1
or
defbuffer2
) or a user-defined buffer
N
The reading number
N
; can be any value from 1 to the number of readings in the buffer;
use the
bufferVar. n
command to determine the number of readings in the buffer
Details
This attribute contains an additional value, such as the extra value written to a writable buffer. The
reading buffer style must be set to full to use this option.
Example
extBuffer = buffer.make(100, buffer.STYLE_WRITABLE_FULL)
buffer.write.format(extBuffer, buffer.UNIT_WATT, buffer.DIGITS_3_5,
buffer.UNIT_WATT, buffer.DIGITS_3_5)
buffer.write.reading(extBuffer, 1, 7)
buffer.write.reading(extBuffer, 2, 8)
buffer.write.reading(extBuffer, 3, 9)
buffer.write.reading(extBuffer, 4, 10)
buffer.write.reading(extBuffer, 5, 11)
buffer.write.reading(extBuffer, 6, 12)
printbuffer(1, 6, extBuffer.readings, extBuffer.units, extBuffer.extravalues,
extBuffer.units)
Creates a 100-point reading buffer named
extBuffer
. Style is full writable.
Set the data format to show units of watts with 3½ digit resolution for the first value and for the second value in
the buffer index.
Write 12 pieces of data into the buffer.
Print the buffer, including the readings and units.
Read the buffer.
Output:
1, Watt DC, 7, Watt DC, 2, Watt DC, 8, Watt DC, 3, Watt DC, 9, Watt DC, 4, Watt DC,
10, Watt DC, 5, Watt DC, 11, Watt DC, 6, Watt DC, 12, Watt DC
