START

Press the ªDATA IN-OUTº softkey in one of the following modes:

PRESET / JOG / AUTOMATIC / INC 1 ... INC 10 000 /

REFPOINT.

You activate the "Block transfer" function by operating the "BTR START" softkey.

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. ºNC Startº 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.
