FN 27: TABWRITE: Write 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.

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, Single Block and Program

Run, Full Sequence operating modes, you can skip
the respective program section by using a jump
command page 198.

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.

Example

You wish to write to the columns “Radius,” “Depth” and “D” in
line 5 of the presently opened table. The value to be written in the
table must be saved in the Q parameters Q5, Q6 and Q7.

53 Q5 = 3.75
54 Q6 = -5
55 Q7 = 7.5
56 FN 27: TABWRITE 5/“RADIUS,DEPTH,D“ = Q5
