12.5 Setting the Data Interface for
the TNC 410
Selecting the setup menu
To setup the data interfaces, press the RS 232- / RS 422 - SETUP soft
key to call a menu for setting the data interfaces:
Setting the OPERATING MODE of the external
device
Setting the BAUD RATE
You can set the BAUD RATE (data transfer speed) from 110 to 115 200
baud. The TNC stores an individual BAUD RATE for each operating
mode (FE, EXT1 etc.).
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
