Please refer to the following for models that support alarm range addressing of Sampling.1.3 Supported Features
When alarms are set up in the data portion, the alarm range is determined by the value before rounding off. Calculations use values after rounding off. As a result, even if the data and calculation have the same alarm range, the display color may be different.
When [Data Type] is [Float], the alarm range is determined by one fractional digit after the defined number of decimal places. As a result, even if the display value is the same, the display color may be different.
For example, displays [10.0] (Digits = 3, Decimal Places = 1), and alarm range is 0 to 10
When actual value is 10.01, displays alarm color
When actual value is 10.001, displays normal color
