3.4 Blockwise Transfer: Testing and Executing Long Programs
– Write the following short program:
0 BEGIN PGM START-UP MM
1 CALL PGM EXT:GEH35K1
2 END PGM START-UP MM
– Select the START-UP program in the PROGRAM RUN/FULL
SEQUENCE mode of operation.
– Select the RESTORE POS AT N function and enter the
desired block number, here 12834, for START-UP AT and the
desired program, here GEH35K1, for PROGRAM.
– Start block scan with the NC START key.

Jumping over blocks
The TNC can jump over blocks to begin transfer at any desired block.
These blocks are then ignored during a program run or test run.
Select the program and start data transfer.
Go to the block number at which you wish to begin data transfer, for
example 150.
Execute the transferred blocks, starting with the block number that
you entered.
Test the transferred blocks, starting with the block number that you
entered.
A tool can be replaced automatically if the maximum tool life (TIME1 or TIME2) has been reached (see page 4-16).
You can use machine parameters (see page 12-11) to define the memory
range to be used during blockwise transfer. This prevents the transferred
program from filling the program memory and disabling the background
programming feature.
As an alternative, you can call the external program with CALL PGM EXT
(see page 6-8) and perform a mid-program startup (see page 3-8).
Example: To perform a mid-program start-up from block 12834 of external
program GEH35K1 proceed as follows:
