Cyclic services
Below is an overview of which cyclic services and parameter update time the device provides. Input
(Master view) is defined as values from the flowmeter to the master. Output (Master view) is defined as
values from the master to the flowmeter. Update time is the interval the flowmeter updates the
parameters.
