4.6.7.4 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 safety CPU cycle)
and saved in the timer identified with the value set for input parameter TIMER.

Description, parameter values
The function block is activated (EN = TRUE) or deac-
tivated (EN = FALSE) via input EN. If the block is
active, the current values are available at the out-
puts.
Watchdog time in ms. The maximum allowed value is
1000. If WDOG is > 1000, then SAFE STOP state
will be entered by the safety CPU.
TRUE sets MAX_TIME to 0.
Output DONE indicates that the set process is fin-
ished.
Actual safety CPU cycle time in ms
Maximal monitored safety CPU cycle time in ms
