Sending and switching delay after bus
voltage recovery in s [2…255]
Options: 2
…255
During the sending and switching delay, telegrams are received only. The telegrams are not processed,
however, and the outputs remain unchanged. No telegrams are sent via 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 communication object values.
If communication objects are read during the sending and switching delay, e.g. by a visualization system,
these read requests are stored, and a response is sent, after the sending and switching delay has been
completed.
An initialization time of about two seconds is included in the delay time. The initialization time is the time
that the processor requires to be ready to function.
How does the device react on bus voltage recovery?
After bus voltage recovery, the device always waits for the transmission delay time to elapse before send-
ing telegrams via the bus.
