3 Operating Sequences 01.93
3.1.15 Data input/data output
Note:
When programming part programs which are to be loaded block-serially into the NC the
following has to be observed:
– @-commands with return jumps are not allowed in main programs. (Alarm 3012 ”Block not
in memory”).
– Forward jumps in the program are possible, even when the jump address does not yet exist
in the circular buffer. The circular buffer is refilled until the target block has been found.
– Subroutine calls are only possible if these subroutines exist in the part program memory of
the NC or in the UMS.
– @-commands with jumps are possible in the subroutine.
– Part programs stored in the circular buffer cannot be edited.
If you discover a programming error you cannot remedy it with the “Corr. Block” function. If
you try, the alarm “No correction block” appears.
– If you call the “Block transfer” function when an interface is still active, the error message
“Interface busy” appears and the program is not started.
– If the “Block transfer” function is already active and if the second interface is actived from
the PLC, the alarm “RS232C (V.24) abort” appears. However, the program running via the
first interface is still processed.
– If the size of the circular buffer is set to zero and the part program memory is newly
formatted, the alarm “Program memory wrongly formatted” appears.
3.1.16 NC in two languages
The standard operator interface texts are available in two languages. The selected language is
marked in the display "Software version display" with an arrow (>).
You can select the "Software version display" via the softkeys DIAGNOSIS and SW
VERSION. The language selection is made in the machine data.
