BTR
START
You activate the ”Block transfer” function by operating
the ”BTR START” softkey.
Press the “DATA IN-OUT” softkey in one of the
following modes:
PRESET / JOG / AUTOMATIC / INC 1 ... INC 10 000 /
REFPOINT.
DATA
IN-OUT
Sequence of operation
This function enables you to run part programs which are too extensive for the part program
memory of the control system (max. 128 kByte).
In this way a part program can be entered and executed from an external storage (punched
tape, diskette, computer) via a standard interface. You enter the program number for
processing in the AUTOMATIC basic display.
After NC-Start of the relevant channel the interface is started for reading in. The ”BTR” display
appears on the screen. You define the interface by entering it into the appropriate screen
display.
All functions such as DEC-SBL, SBL, ... may be used as in normal operation.
Block search is also possible without restrictions. The interface is then started with the ”Block
search start” softkey. ”NC Start” resumes normal operation after block search.
The current block is indicated in the AUTOMATIC basic display as well as during normal
operation.
When data are being transmitted, the program number selected from the AUTOMATIC basic
display is compared with the program number received from the external storage. It is only
possible to select a main program. If the program numbers are not identical, an error message
will appear. Otherwise the program is executed.
If you have entered 0 as program number in the AUTOMATIC basic display, the incoming
program number will not be checked. This enables you to read in a program of which you do
not know the program number.
