4.6.4.4 SF_APPL_MEASURE_BEGIN
Defining the start point of time profiling
This function defines the start point of time profiling within safety application program and shall be used
together with SF_APPL_MEASURE_END function. The time profiling results can be seen only using
"applinfo" PLC Browser command and cannot be used within safety application program.
The time between the calls of SF_APPL_MEASURE_BEGIN and SF_APPL_MEASURE_END functions in
the safety application program is measured (including within one SM560-S cycle) and saved in the timer
identified with the value set for input parameter TIMER.
NOTICE!
SF_APPL_MEASURE_BEGIN function was developed for measuring short time intervals only, which
means that for time intervals of ~ 10 minutes and longer, it produces invalid results.
