Time use evaluation of synchronized actions

Function
In a interpolation cycle, synchronized actions have to be both interpreted and motions
calculated by the NC. The system variables presented below provide synchronized actions
with information about the current time shares that synchronized actions have of the
interpolation cycle and about the computation time of the position controllers.
Significance
The variables only have valid values if machine data $MN_IPO_MAX_LOAD is greater than 0.
Otherwise the variables for both SINUMERIK powerline and solution line systems always
specify the net computing time during which the interrupts caused by HMI are no longer taken
into account. The net computing time results from:
• synchronized action time,
• position control time and
• remaining IPO computing time without interrupts caused by HMI
