Sending and switching delay after bus voltage recovery

Options:
During the sending and switching delay, telegrams are only received. However, the telegrams are not
processed and the outputs remain unchanged. No telegrams are sent on the bus.
After the sending and switching delay, telegrams are sent and the state of the outputs is set to correspond
with the parameterization or the group object values.
If group objects are read out via the bus during the sending and switching delay, e.g. by a visual display
system, these requests are stored and a response is sent once the delay time has expired.
An initialization time of about two seconds is included in the delay time. The initialization time is the time
that the processor requires before it is ready to function.
After bus voltage recovery, the device always waits for the sending delay time to elapse before sending
telegrams via the bus.
In controller mode, the switching delay set does not apply to the parameterized behavior of the outputs
