If you start in a point table called by the main program, use the

If you would like to start with the mid-program startup in a point
pattern, then proceed just as you would for starting in the point
table. Enter the desired point number in the Point number = input

Block scan in pallet programs
With the pallet management you can also use the BLOCK SCAN
function in conjunction with pallet tables.
If you interrupt the processing of pallet tables, the control always
suggests the previously selected NC block of the interrupted NC
program for the BLOCK SCAN function.
For BLOCK SCAN in pallet tables, you also define the
Pallet line = input field. The input refers to the line in
the NR pallet table. This input is always required as an
NC program may appear several times in a pallet table.
The BLOCK SCAN always takes place in a workpiece-
oriented manner, even if you have selected the
machining method TO and CTO. After the BLOCK SCAN,
the control continues working again in accordance with
the selected machining method.
Press the BLOCK SCAN soft key
The control shows a pop-up window.
Pallet line = Enter the row number of the pallet
table
Enter Repetitions = if the NC block is located
within a program section repetition
Press the NC Start key
