Unload via NC program
(SINUMERIK 880/880 GA2 only)
Description
The function block transmits the function code of the unloading type which can be set via the
softkey "SELECT" in the display "Unload via NC program" to the FB tape output (FB 120).
The function code is only transferred if no program is running and no program is interrupted.
The bit "Mark tool for unloading" is set in the function block by selecting the tool in the display
"Mark tool for unloading" using the cursor. If the selected location is not assigned, an
interactive text stating an error is output.
The block checks whether AUTOMATIC mode has been selected and that no program is
active in channel 1. If this is not the case, an interactive text stating an error is output and the
next menu cannot be selected.
NC Reset is set if the display "Unload via NC program" has been selected and the softkey
"Abort/Reset" has been pressed or AUTOMATIC mode has been deselected during "Tape
output active".
