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.
Function Range Related object
1-byte (unsigned int.) 0– 255 [Pn][Bi] 1-byte unsigned int indicator
1-byte (signed int.) -128 – 127 [Pn][Bi] 1-byte signed int indicator
Percentage indicator 0% – 100% [Pn][Bi] Percentage indicator
2-byte (unsigned int.) 0 – 65535 [Pn][Bi] 2-byte unsigned int indicator
2-byte (signed int.) -32768 – 32767 [Pn][Bi] 2-byte signed int indicator
2-byte (floating point) -671088.64 – 670760.96 [Pn][Bi] 2-byte float indicator
Table 1 Numerical indicators
The table contains the allowed value ranges and the name of the object for
each case.
In the particular case of the 2-byte floating point indicator, the integrator will be
shown a text field (Float Unit), empty by default, that permits specifying the
measuring units (up to 6 characters) of the displayed value, for instance “ºC”.
Moreover, for this particular case, 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).
All these numerical indicators incorporate an additional parameter, Save Log?.
In case of enabling this option (“Yes”), any changes in the value of the indicator
will be continuously saved to an internal log file, so the final user can be
afterwards offered a visual representation that reflects the chronological
evolution of such value. Boxes for which this option has been enabled will show
a small icon overlaid on their upper left corner.
