Trigger
Disable: The command is never sent
Cyclic: The command is sent cyclically at the interval specified in the
Poll Interval
parameter.
Data change: The data area is polled for changes at the time interval defined by Poll
Interval. A command is issued when a change in data is detected.
Poll interval
Polling intervals are in milliseconds; since the module sends all requests in turns,
the actual polling interval also depends on the number of requests in the queue and
their parameters. The range is from 10 to 1,200,000 ms.
