4.3.5 Output devices
The output devices set the validation of the start devices according to their function in the lo-
gical nominal states of the output circuits and message outputs.
In the AS-Interface safety monitor, a shutdown system consists of a redundantly constructed
relay output and a message output. If two shutdown systems are present in one monitor, the
second shutdown system can be operated dependently or independently of the first. The out-
put devices differ from one another at this point.
The conversion of the logical to the physical switching state for relays, message outputs and
LEDs is then performed in the hardware of the AS-Interface safety monitor. A false switching
state in the hardware detected when reading the data back in also results in the switching of
the affected output device to the error state.
Note
For two independent OSSDs, exactly one output device must be present for each OSSD.
For two dependent OSSDs, exactly one output device in the 1st OSSD establishes the depen-
dence.
