All the components are supplied in particular hardware and software configurations appropriate for the application. Modifications to hardware or software configurations other than those described in the documentation are not permitted, and nullify the liability of Beckhoff Automation GmbH & Co. KG. Personnel qualification This description is only intended for trained specialists in control, automation and drive engineering who are familiar with the applicable national standards. -
Page 7: Documentation Issue Status
The firmware and hardware versions (delivery state) of the terminal can be found in the serial number printed on the side. The KL6821 from firmware 08 and hardware 08 is DALI-2 certified and can be clearly identified by the DALI-2 logo on the terminal side. -
Page 8: Product Overview
Introduction Fig. 1: KL6821 The KL6821 allows the connection of up to 64 DALI control gears and up to 63 DALI-2 control devices. The KS2000 configuration software facilitates parameterization via a PC. The KL6821 contains an integrated DALI-2 power supply that can be switched off with electrically isolated output voltage. No further components are required for operation of the DALI devices. -

(IEC 62386) allows the manufacturers of lighting components to implement complex lighting tasks easily and conveniently. The KL6811 (DALI version-1/DSI) and KL6821/EL6821 (DALI-2) Bus Terminals are integrated into the bus terminal system and are therefore fieldbus-independent. The DALI data is forwarded to the DALI devices via the respective bus coupler. -
Page 11: Communication
Product overview Up to 64 DALI control gears and up to 64 DALI control devices can be connected to the KL6821 per DALI line. The KL6821 represents the DALI controller. One such device exists for each DALI line. Up to 64 control gears, which have to be DALI/DSI devices, can be connected to the KL6811. -
Page 12: Priorities
Most function blocks referred to in chapter Part 102 (control gears) have the input eCommandPriority. This input is used to specify the priority with which the DALI commands are to be sent via the KL6821. Events also have a priority (event priority), which is represented by the data type E_DALIEventPriority. Event priorities can have 4 values in the range Low (DALI priority 5) to Middle high (DALI priority 2). -
Page 13: Bus Timing
Priorities are always important in situations where DALI sensors (input devices) send events and DALI commands are sent in parallel via the KL6821. If no DALI sensors (input devices) are used, the priority of the DALI commands is of secondary importance, since in this case there is only one DALI master (the KL6821). - Page 14 17.0 ms + (17 x 0.833 ms) + 8.0 ms + (9 x 0.833 ms) = 46.7 ms. 16-bit telegram send-twice: 17.0 ms + (17 x 0.833 ms) + 14.1 ms + (17 x 0.833 ms) = 59.4 ms.

- Page 15 If the break sequence is finished at DALI device 2, the DALI bus is not occupied by any other DALI device (point D). Therefore the recover sequence is started at DALI device 2 and then the DALI telegram is sent again directly (without settling time). KL6821 Version: 1.0.0...
- Page 16 The times in the top line (4 ms ... 80 ms) specify the cycle time of the PLC task from which the DALI commands are started. The times (2 ms ... 30 ms) in the first column specify the cycle time of the PLC task for background communication. Version: 1.0.0 KL6821...

Memory bank 0 is read only and contains general, vendor-specific information about the DALI control gear or DALI control device. Every certified DALI device must implement memory bank 0. Up to offset 16#1A the fields are defined by IEC 62386 as follows.

Page 19: Dali-2 Current
2.3.6 DALI-2 current The DALI power supply of the KL6821 has a maximum output current of 250 mA and a guaranteed DALI current of 220 mA. To ensure safe operation of the DALI bus, the connected DALI devices must never consume more than the guaranteed DALI-2 current in total. -
Page 20: Fig. 2 Dali-2 Current
Furthermore, a reserve specified in IEC 62386 (guaranteed DALI current / 1.2) should be maintained. This reserve is intended for the subsequent installation of additional devices that may be added in the course of a project. Fig. 2: DALI-2 current Version: 1.0.0 KL6821... -
Page 21: Mounting And Wiring
• Surroundings (working place, packaging and personnel) should by grounded probably, when handling with the devices. • Each assembly must be terminated at the right hand end with a KL9010 bus end terminal, to ensure the protection class and ESD protection.

Page 25: Connection
Insert the new component and plug in the connector with the wiring. This reduces the installation time and eliminates the risk of wires being mixed up. The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3 mm. The maximum height of the terminal remains unchanged. KL6821 Version: 1.0.0... -
