Timeout
l
Sets the maximum permissible time between a request and a response
before an error status is shown. In the event of an error, a "wire-break"
status is displayed (refer also to the table in Status monitoring). The time
must be short enough in relation to the time for the Poll cycle or you will
receive an error message when closing the dialogue. The values entered will
then not be saved.
Pause
l
Sets the waiting time for a query from more than one channel within a poll
cycle. The time must be short enough for all channels to be queried within
the time entered under Poll cycle or you will receive an error message when
closing the dialogue. The values entered will then not be saved.

If you enable this option, only one request telegram will be generated for
sequential Modbus addresses instead of a separate request telegram for
each address.
