Commissioning EL6821

From TwinCAT 3.1.4024.57, dialogs are available for the commissioning and diagnosis of DALI devices on the EL6821.

The dialogs offer not only functions for addressing DALI control gears and DALI control devices, but also for writing and reading parameters. The search function automatically detects the DALI device types and displays them in a tree structure.

Furthermore, all parameters of the EL6821 can be set via TwinCAT XAE. This makes it possible, for example, to define the DALI commands that are sent when the digital inputs on the EL6821 are actuated.

Overview of the most important functions in the TwinCAT XAE for the EL6821:

• Find DALI devices
• Addressing the DALI devices, including adapting the short addresses
• Scene and group assignment of the DALI control gears
• Configuration of the DALI control gears, including the parameters for the different device types
• Configuration of the DALI control devices, including the parameters for the different sensor types
• Writing/reading of the memory banks
• Definition of DALI commands for DI1 and DI2 (separate for rising and falling edge)
• Definition of the DALI command for the E-bus watchdog (E-bus failure)
• Switching the DALI power supply unit on/off
• Activation/deactivation of the blocking of the process image for the PLC as soon as a DALI command is sent by actuating a digital input on the EL6821.
