Table 151: Settings - LEDs 1-6/LED Direct buttons 1-4
Each LED can react either to any external object, such as the status of an actuator, an internal object
or the activation of a button. In addition, an LED can also react to an external or internal object and
the key operation. With this setting, the settings in menu LED 1-6/LED direct buttons 1-4 refer to the
control of the LED via the object. In this case, the behaviour of the key operation is set globally for all
LEDs and is described in menu 4.11.1 LED . The behaviour for key operation has priority.
If the setting LED reacts to "internal object" is selected, the object number with which the LED is to
be linked is selected. If the LED is to switch when the "Object 1 - Value for switchover" has the value
1, the object number 1 is to be entered. In this case the status LED would be switched on if the object
has a 1 and switched off if the object has a 0. If the LED is linked to an object which does not have a 1
bit size, the LED is switched off if the object has the value 0 and switched on if the value of the object
is not equal to 0. For an object of the DPT 5.001 - percent this would mean that the LED is switched
off at 0% and switched on at all other values.
Each LED can assume different colours and behaviour for day and night operation and switches on
depending on the object 121-Day/Night.
