3.3 Blockwise Transfer: Executing Long Programs
Part programs that occupy more memory than the TNC provides can be
“drip fed” block by block from an external storage device.
During program run, the TNC transfers program blocks from a floppy disk
unit or PC through its data interface, and erases them after execution.
To prepare for blockwise transfer:
l
Prepare the data interface.
l
Configure the data interface with the MOD function (see page 1 l-5).
l
If you wish to transfer a part program from a PC, adapt the
TNC and PC to each other (see pages IO-4 and 12-3).
l
Ensure that the transferred program meets the following requirements:
- The highest block number must not exceed 65534. However, the
block numbers can repeat themselves as often as necessary.
- All programs called from the transferred program must be present in
the control’s memory.
- The transferred program must not contain:
Subprograms
Program section repeats
The function FN15:PRINT
- The TNC can store up to 20 TOOL DEF blocks.
