This condition can be a potential hazard depending on the application, for
instance, if the sensor responsible for the changeover does not respond. In
the safety functional example this condition is detected and compared with
a parameterized time. If this condition continues to be true after this time
has elapsed, this will be interpreted as an error and the #ERR_SW_TIME
bit will be set (see network 5).
