For the 2-byte float data type, it is possible to define the number of decimal places to show
(
Decimal places
parameter). This can be set to 0, 1, 2, or Automatic; with the “Automatic” option,
the number of decimal places to show is determined automatically by the device, depending
the actual object value:
• Two decimal places if the absolute value is less than 1
• One decimal place if the absolute value is 1 or greater, and less than 100
• No decimal places if the absolute value is 100 or greater
Finally, for all data types except “Percentage”, a text suffix (
Units
parameter) can be added to
represent value units, such as “ºC”. This suffix will be displayed immediately after the numeric
object value.

Level bar indicators are similar to numerical indicators, and support the same data types, but
the value of the associated communication object is represented as a level bar. In addition, the
value is also displayed in textual form above the level bar.
The
Minimum bar value
and
Maximum bar value
parameters allow to limit the effective range of
values that are used to determine the bar level. Values that are outside this effective range will
be represented as an empty or full bar, respectively. The textual representation of the value is
not affected by these parameters.
