Short description
of the
functionality
The functionality of the Balluff status light module can be controlled through process data
and ISDU registers. It has four main mode of functionality:
Segment mode
Level mode
Runlight mode
Flexible mode*
With the help of these four modes various warning and indication signals can be indicated.
The buzzer function is available in all modes. The synchronisation* is available in segment
and runlight mode and if the Smartlight contains buzzer it is also available in level and
flexible mode.
3.8
Segment mode
To use the module as a standard status light, the Mode ISDU register must be set to
segment mode. In the segment mode the module can be used as a standard status light,
with configurable number of segments. Maximum five segments can be set. Irrespectively
of the selected number of segments, always all of the LEDs are used as a display element.
The number of the segments can be set any number between 1 and 5. The module has 20
LEDs, which are equally distributed between the segments. (When three segments are set,
one-one LEDs between the segments will be always switched off). The color of each
segment can be selected from a color table, which has six pre-defined colors and one user
defined color. The combinations of the pre-defined colors are not limited. In the segment
mode, the segments can be set to blink too. Each segment has a control bit in process
data, which determines the blinking of the corresponding segment. The blinking has two
modus. Either normal blinking or flash mode can be selected. In normal blinking the LEDs
are switched on and off periodically with a 50% duty cycle. In the flash mode, the LEDs are
switched on and off quickly three times. The flash is repeated in every second. The type of
the blinking can be set in ISDU register. The frequency of the normal blinking can be
changed through an ISDU register.
3.9
Level mode
To use the signal light as a level meter, the Mode ISDU register must be set to level mode.
In level mode the complete module works as one indicator element. In this case a level
value can be displayed. The process data does not give the colors of the segment, but the
level. The higher value the module becomes, the more LEDs will be switched on. This
mode can be used as a level indicator, for example to indicate a fluid level in a tank. The
resolution of the input level can be selected from 8 bit up to 16 bit. In the level mode various
parameters can be controlled through ISDU registers. These parameters should be set
before the level mode is used. The level display can be selected to be bottom-up or top-
down. In the bottom-up mode the level indicator increases from the bottom of the module.
In the top-down mode the indicator increases from the top of the module.
Although there are no real segments in the level mode, because the LEDs are controlled by
the input level, the LEDs are divided into five virtual segments. These virtual segments can
have their own color. The color of these segments can be set through ISDU register (Level
mode segment x color ISDU register). So it can be realized, that the level meter can have
more colors (up to the maximum number of the segments). Some or all colors can be set as
dominant color. This means, when the input level is high enough to switch on the next LED
and this LED is in another virtual segment, the LEDs, which are under the actual LED, take
over the color of the actual LED. In this case, as the input level increases, the color of the
full LED bar can be changed.
For example:
The lower two segments are green, the middle two segments are yellow and the upper
segment is red. The LEDs are shown in the next figures, when the Smartlight level mode is
configured differently.
