FN 28: TABREAD: Reading a freely definable
table
After you have opened a table with FN 26: TABOPEN, you can use
function FN 28: TABREAD to read from it.
You can define up to 8 column names for reading in a TABREAD block.
The column names must be written between quotation marks and
separated by a comma. In the FN 28 block you can define the
Q parameter number in which the TNC is to write the value that is first
read.
Example:
You wish to read the values of the columns “Radius,” “Depth” and
“D” from line 6 of the presently opened table. Save the first value in
Q parameter Q10 (second value in Q11, third value in Q12).
You can read only numerical table fields.
If you wish to read from more than one column in a block,
the TNC will save the values under successive
Q parameter numbers.
