Screen refresh behavior for overload - only 840D sl

There are part programs, where the main run must wait until the preprocessing run provides
new blocks.
Preprocessing run and display refresh compete for NC processor time.
The following machine data can be used to set how the NC should behave if the preprocessing
run is too slow:
MD10131 $MN_SUPPRESS_SCREEN_REFRESH
Value Meaning
0 If the preprocessing run of a channel is too slow, the display is not refreshed in all channels.
1 If the preprocessing run of a channel is too slow, the display is only refreshed in the time critical channels in order
to obtain processor time for the preprocessing run.
2 Display refresh is not suppressed.
