D27 – Write to a freely definable table
With the D27 function you write to the table that you previously
opened with D26.
You can define multiple column names in a D27 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 D27 function by default writes values to the
currently open table, even in the Test Run operating
mode. The D18 ID992 NR16 function allows you to
retrieve the operating mode in which the program is
running. If the D27 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.

parameters", page 348
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.
N53 Q5 = 3.75
N54 Q6 = -5
N55 Q7 = 7.5
N56 D27 P01 5/"RADIUS,DEPTH,D" = Q5
