Notice
The logical evaluation whether the timeout value is exceeded, is time-delayed by
the system. This must be taken into account if actions that can only capture
realtime data are triggered by the timeout trigger. It is not possible to capture
precisely timed data from the cycle in which the timeout took place (max. delay in
the minute range).
Due to system dependencies, repeatability of the timeout function is also linked to
the communication runtimes which depend on the demands placed on the
interface between PLC and PC of the operator. As a rule, repeats can be
implemented within a second, but expect several seconds with a high interface
load.
