7.3.1.1 Changing the resolution
In order to change the resolution of the process value shown in the operation view (for
example mass flow), set the decimal places parameter for the selected process value, for
example the decimal places for process value Mass flow is defined in Decimal places
(2.2.2.4).
The resolution can also be changed by changing the resolution of one configuration
parameter for this process value (for example Low flow cut-off (2.2.2.5)). Any changes in
resolution will change the resolution of all configuration parameters for this process value as
well.
