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).
