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.
You can use machine parameter MP7228 (see page 11-12) 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.
Example: To perform a mid-program start-up from block 12834 of external
program GEH35K1 proceed as follows:
– Write the following short program:
%START-UP G71
N10 % EXT:GEH35K1
N99999 %START-UP G71
– 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.
