Settings of higher-level parameters:
Sending and switching delay
after bus voltage recovery
Options: 2/3/5/10/30/60 seconds
2/3/4 minutes
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 communication object values.
If communication 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 to be ready to function.
How does the device react on bus voltage recovery?
After bus voltage recovery, the device always waits for the sending delay time to elapse before
sending telegrams via the bus.
Note
The set switching delay does not act on the valve outputs!
