2 Overview
2.1 Overview Devices
The description refers to the following LED Indicators (order shown in bold):
•SCN-LED55.01 LED-Indicator, 55mm
o12 RGBW LEDs, Logic and Converter functions
•SCN-GLED1W.01 Glass LED-Indicator, white
o12 RGBW LEDs, Logic and Converter functions
•SCN-GLED1S.01 Glass LED-Indicator, black
o12 RGBW LEDs, Logic and Converter functions
2.2 Usage & Areas of application LED Indicator
The LED Indicator serves as a reminder of certain states. In this case, each of the 12 LEDs can be
either normally switched on or flash in four different colors (red, green, blue, white) to show any
state. The 6 row elements can be individually labeled in both designs, the glass LED Indicator as well
as the 55mm LED Indicator.
In addition, the display features 8 logic blocks as well as an alarm and converter function. Via the
logic function, states or functions can be evaluated in detail by using AND/OR functions. In response
to its states, byte values or scene numbers can be sent.
Through the built-in alarm function interrupts can be triggered with the signal change of any LED. To
this end, 4 different alarm objects are available.
By using the converter function, temperature values, byte values and 2-bit values can be converted
to simple bit values.

2.5 Start Up
After wiring, the allocation of the physical address and the parameterization of every channel follow:
(1) Connect the interface with the bus, e.g. MDT USB interface
(2) set bus power up
(3) Press the programming button at the device(red programming LED lights)
(4) Loading of the physical address out of the ETS-Software by using the interface(red LED goes
out, as well this process was completed successful)
(5) Loading of the application, with requested parameterization
(6) If the device is enabled you can test the requested functions(also possible by using the ETS-
Software)

Table 2: Default Settings communication objects
You can see the default values for the communication objects from the upper chart. According to
requirements the priority of the particular communication objects as well as the flags can be
adjusted by the user. The flags allocates the function of the objects in the programming thereby
stands C for communication, R for Read, W for write, T for transmit and U for update.

4.2 LED-Settings
Every of the 12 LEDs can be adjusted and controlled individually. The parameters for LED 1 are
described. LEDs 2-12 have the same parameters.

Furthermore, the LED can respond to internal objects. Both the internal logic objects and the internal
converter objects are available. In order to reduce the design effort, in this case the connection is
made internally. This additional parameter is displayed, which sets the internal connection.
For the setting "LED responds to internal logic object" looks as follows:
Figure 5: LED control via internal logic object:
In this example, the LED is switched in response to the output of the first logic function. This driving
course is designed so that the output of logic module is a bit value. If the logic module is set as a byte
value or scene, the LED is turned off with the value 0, all others turn the LED on.

The settings for the LED display behavior behavior are identical for the setting with LED object value
1, as well as for the LED priority settings.
4.2.3 LED Priority
By using the LED priority, it is possible to switch the LED of prime importance. So the value of the
normal LED control will be overwritten. Two LED priorities are available. The priority of the LED
controlling is staggered as follows (from high to low priority): LED Priority 1→LED Priority 2 →
normal LED Control.
The settings for the LED priority (settings for Led priority 2 are identical) are as follows:

Figure 8: Settings LED priority 1/2
The activation of the LED priority can be done via external objects, internal logic objects or internal
converter objects. The settings are the same as described in 4.2.1 LED Control.
Standardly, the priority is activated with the value 1. Via the parameter “invert object”, the priority
can be set as active at the value 0.
The display behavior of the LED at activation of the LED priority is the same like described in 4.2.2
LED Display behavior, but can be set individually for the LED priority.
If the parameter “Assignment of communication objects” is set to external object, an additional
object is shown, which can be connected individually:

4.2.4 Monitoring
Via the monitoring of the LEDs, it can be controlled if the LED indicator gets in defined time steps a
signal from the external object. If the LED indicator receives no signal, a particular behavior can be
called, e.g. flashing red.
The following picture shows the available settings for the monitoring:

▪no monitoring
▪1min –240min

Table 9: Monitoring
The display behavior in case of a loss of the signal is the same like in 4.2.2 LED Display behavior
described.
It should be noted that monitoring can be enabled only when the parameter "LED reacts on” is set
to “external object", because the LED indicator cannot monitor itself.
In addition, at failures an object can be set, which indicates a loss of a signal. This must be activated
in the general settings:

4.2.5 Behavior after Reset
After a bus voltage reset, or download, the objects for the LED have no value and therefore no
defined switching state. To produce a defined state for this case, the setting is shown below:

4.3 Alarm function
The LED Indicator contains of an extensive alarm-function, which can monitor LEDs in the absent
mode. As soon as a LED gets a certain value, this can be signaled by sending a one-command on one
of four freely adjustable alarm objects. Both the LEDs and the LED 1 priority of all LEDs can be
monitored.
The settings for the LED1 can be seen in the pictures below:
