Numerical value
This screen element allows you to display untreated or
scaled signal states in decimal format.
Value and scaling range
The value range determines the range of values to be
displayed. The display system indicates an underflow if the
values are below this range and an overflow if they are
above it.
The scaling range enables the value range to be scaled. To
do this, the lower value of the scaling range is assigned to
the lower value of the value range and the upper value of the
scaling range is assigned to the upper value of the value
range. If no scaling range is defined, the display system
displays the value range.
Examples:
If you wish to display the value range (0 to 255) for example
from a counter as a percentage (0 to 100%), then enter 0 as
the minimum value and 255 as the maximum value in the
Value range area. Enter “%” as a unit of measure. Activate
the Scaling range area and enter 0 as the minimum value
and 100 as the maximum value.
If you wish to display the value range from 0 to 120 seconds,
for example, from a timing relay in minutes (0 to 2 min),
enter 0 as the minimum value and 120 as maximum value in
the Value range area. Enter “min” as a unit of measure.
Activate the Scaling range area and enter 0 as the minimum
value and 2 as the maximum value.
Programming in CL-SOFT:
