3 Test Run and Program Run<br />
3.3 Blockwise Transfer: Executing Long Programs<br />
3-6<br />
Part programs that occupy more memory than the <strong>TNC</strong> provides can be<br />
“drip fed” block by block from an external storage device.<br />
During program run, the <strong>TNC</strong> transfers program blocks from a floppy disk<br />
unit or PC through its data interface, and erases them after execution.<br />
To prepare for blockwise transfer:<br />
• Prepare the data interface.<br />
• Configure the data interface with the MOD function (see page 10-3).<br />
• If you wish to transfer a part program from a PC, adapt the <strong>TNC</strong> and PC<br />
to each other (see pages 9-4 and 11-2).<br />
• Ensure that the transferred program meets the following requirements:<br />
- The highest block number must not exceed 65534. However, the<br />
block numbers can repeat themselves as often as necessary.<br />
- All programs called from the transferred program must be present in<br />
the <strong>TNC</strong> memory<br />
- The transferred program must not contain:<br />
Subprograms<br />
Program section repetitions<br />
The function D 15:PRINT<br />
- The <strong>TNC</strong> can store up to 20 G99 blocks.<br />

Select the function for blockwise transfer.<br />
Enter the program number and start data transfer.<br />
Execute the transferred program blocks.<br />
If the data transfer is interrupted, press the machine START button again.<br />
