FN 27: TABWRITE: Writing to a freely definable
table
After you have opened a table with FN 26: TABOPEN, you can use the
function FN 27: TABWRITE to write to it.
You can define and write to several column names in a TABWRITE
block. The column names must be written between quotation marks
and separated by a comma. You define the values that the TNC is to
write to the respective column with Q parameters.
Example:
You wish to write to the columns "Radius," "Depth" and "D" in line 5 of
the presently opened table. The values to be written to the table must
be saved in the Q parameters Q5, Q6 and Q7.
Note that by default the FN 27: TABWRITE function writes
values to the currently open table also in the Test Run
mode. The FN18 ID992 NR16 function enables you to query
in which operating mode the program is to be run. If the
FN27
function is to be run only in the Program Run
operating modes, you can skip the respective program
section by using a jump command (see "If-then decisions
with Q parameters" on page 189).
You can write only to numerical table fields.
If you wish to write to more than one column in a block,
you must save the values under successive Q parameter
numbers.
