Creating the memory for blockwise transfer
In order to be able to edit other programs while blockwise
execution is in progress, you need to create a memory for
blockwise transfer.
The TNC shows the available free memory space. The reserved
memory space should be less than the total free memory space
available.
Setting the block buffer
To ensure a continuous program run during blockwise transfer, the
TNC needs a certain quantity of blocks stored in program memory.
In the block buffer you define how many NC blocks are read in
through the data interface before the TNC begins the program run.
The input value for the block buffer depends on the point intervals
in the part program. For very small point intervals, enter a large
block buffer. For large point intervals, enter a small block buffer.
Proposed value: 1000
Software for data transfer
For transfer of files to and from the TNC, we recommend using the
HEIDENHAIN TNCremo data transfer software. With TNCremo, data
transfer is possible with all HEIDENHAIN controls via serial
interface.
Please contact your HEIDENHAIN agent if you would like
to receive the TNCremo data transfer software for a
nominal fee.
