A function block keeping track of all G-Code sentence numbers that have been processed and removed from the jump buffer. If no buffer is provided, the default implementation SMC_MonotoneSentenceHistory will be used.
udiRefillWindowSizePercentage
UDINT
10
The amount of elements that is read and removed in one cycle and added in the next cycle, when no jump has been requested (if
ncprogOut.bRestart=FALSE
). Provided in percent of the current buffer level and defaults to a minimum value of 10. A larger center window will slightly improve reading performance for long cycle times, while reducing the buffer’s chances to have a requested jump target actually buffered.Output
