2.12.4 Measurable time ranges

The scope of time that can be measured via timers using Run-Break Timer events (see "2.12.2 Measure execution time until stop of the execution" for details) or Timer Result events (see "2.12.3 Measure execution time in a section [IECUBE][Simulator]" for details) is shown below.

If the maximum measurable length of time is exceeded, a timer-over break is generated, and program execution stops.
