4.3.2 Extended overstore
Machine manufacturer
The softkey function "Extended overstore" must be configured by the machine
manufacturer.
"Extended overstore" makes it possible to overstore by executing whole NC
program blocks or a single NC program.
With this function, traversing blocks or programs are executed when a channel
is in the RESET or stop state by inserting MDA mode without making a mode
change or RESET necessary. The program state and point of interruption are
"noted". The overstore program is processed and processing is then continued
from the point of interruption.
