Numerical Indicators
Figure 67
1-Byte Indicator (Unsigned Integer)
The remaining functions under Indicator are shown in Table 1. In all of these cases, the
box will behave as a numerical state indicator that permanently displays the value of a
certain communication object, which is enabled when the function is assigned to the box.

Table 1
Numerical indicators
The table also reflects the allowed value ranges and the name of the object for each
case.
In all cases the integrator will be shown a text field (
Unit
), empty by default, that permits
specifying the measuring units (up to 6 characters) of the displayed value. For
percentage indicators, the symbol % always will be displayed as unit.
In the particular case of the floating point indicators (2-byte or 4-byte), the device will
dynamically adjust the number of the decimal figures shown depending on the order of
magnitude of the current value: two for values greater than 0 and lower than 0.1; one for
values between 0.1 and 100; and none for other cases (and analogously for negative
values).
