FN 27: TABWRITE
– Write to a freely definable table
With the
FN 27: TABWRITE
function you write to the table that you
previously opened with
FN 26: TABOPEN
.
You can define multiple column names in a
TABWRITE
block. The
column names must be written between quotation marks and
separated by a comma. You define in Q parameters the value that
the control is to write to the respective column.
The
FN 27: TABWRITE
function by default writes
values to the currently open table, even in the
Test
Run
operating mode. The
FN 18 ID992 NR16
function
allows you to retrieve the operating mode in which the
program is running. 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 statement.
Further information: "If-then decisions with Q
parameters", page 386
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
