DALI Lamp for Emergency Lighting
This modul is used to control DALI ballasts for emergency lighting. In order to build groups with standard lamps, the original range of 0..254 for an DALI-lamp displayed in percentage. The calculation is linear: 0% means 0 (DALI), 50% means 127 (DALI) and 100% means 254 (DALI).
Settings
Parameters
- Minimum Control Value: The minimum value, to which the lamp can be dimmed.
- Maximum Control Value: The maximum value, to which the lamp can be dimmed. Changing these values does not affect the ballast internal min and max values, which will always prevail.
- Fade Rate: The amount by which the lamps value is increased / decreased with a Fade Up / Fade Down-command.
- Startup Control Value: Initial value of the lamp when the PLC-application is started. If the lamp is explicitly set to a value lower than its minimum or greater than its maximum value, it will be automatically set to the appropriate limit. The exception is 0%, which turns the lamp off.
- System Failure Level: The system failure level of the DALI-lamp. This is the level of the lamp in case of a disconnection from the DALI-terminal.
- Cycle Time Query Control Value: Since not all DALI-commands change the ballasts to an absolute value, it is necessary to query the actual value from time to time. This entry defines the interval.
- Resetting Mode: When selected, the last value, before turning the lamp off will be stored. If the lamp is turned on again by the On-command, it will be set back to this value.
Subsystem Assignment
- Short Address: The short address of the assigned DALI-device.
- Linked to...: The DALI-line, at which the ballast is installed, must be entered here. Once the button is activated, a window will open, where the DALI-terminal can be chosen.

Commands
- Fade Up: This command will increase the light-value by the entered fade-rate. The command will only work when the lamp is already turned on. Increasing the value above the maximum level is not possible.
- Fade Down: This command decreases the light value by the entered fade-rate but will not let a lamp turn off completely.
- On: Turns the lamp either to the maximum or the Resetting Value, which depends on the fact, if the Resetting Mode is activated or not.
- Off: Turns the assigned lamps off. When the Resetting Mode is activated the light value prior to the off-state will be stored.
- Call Maximum Control Value: The lamp will be turned to its maximum level.
- Call Minimum Control Value: The lamp will be turned to its minimum level.
- Set Control Value Direct: The entered value will be taken over, when the Apply-button is pressed. If the lamp is explicitly set to a value lower than its minimum or greater than its maximum value, it will be automatically set to the appropriate limit. The exception is 0%, which turns the lamp off.
- Set Operating Hour Counter Direct: The entered value will be taken over, when the Apply-button is pressed.
State
- Control Value: Actual output value. If the lamp is set to a new value, it will be shown in the Control Value-field first, even if the lamp does not have reached this level, yet, due to a high device internal fade-time. The lamp may slowly dim to its end-level and a short Cycle Time Query Control Value will make the dimming visible. In the end, the lamp will be set closest possible percentage-value.
- Resetting Value: When Resetting Mode is selected and the lamp is turned off, the last value, before turning off will be stored. If the lamp is turned on again by the ON-command, it will be set back to this value.
- Operating Hour Counter: Service life of the lamp.
State PLC Module
- Execution State: Shows if the module is running or stopped.
- Error: In case of an error, the error code and the error parameter are displayed in this box.
- Start/Stop: Starts/stops the module.
