Notice
Due to system dependencies, repeatability of the stopwatch function is linked to
the communication runtimes, which depend on the demands placed on the
interface between PLC and PC of the operator. Repetitions can usually be
implemented in less than one second. With high interface traffic, however, they
can take several seconds.
