General parameter window
Setting top-level parameters:
Sending delay after bus voltage recovery,
download and ETS reset
Options:
2…255 s
During the sending and switching delay, telegrams are only received. However, the telegrams are not
processed and no commands are sent on the bus or to the split unit.
After the sending and switching delay time, telegrams are sent on the bus and the state of the split unit is
set according to the parametrization or group object values.
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.
How does the device react on bus voltage recovery?
After bus voltage recovery, the device always waits for the sending and switching delay time to
expire before sending telegrams on the bus.
