EL6821 - Devices diagnostic functions
The CoE directory can be used to read diagnostic information on DALI communication (0xA000:0 "Diag") and the LED status (object 0xF915:0 "LED status").
Diagnostics via object 0xA000:0
The terminal has integrated diagnostics that can be read in object 0xA000:0.

|---|---|---|
0xA000:01 | Frames on DALI Bus | Frames on DALI bus |
0xA000:09 | Received DALI 16 Bit Frames | Received DALI 16-bit frames |
0xA000:0A | Received DALI 24 Bit Frames | Received DALI 24-bit frames |
0xA000:0C | Received DALI 32 Bit Frames | Received DALI 32-bit frames |
0xA000:0E | Received Backward Frames | Received DALI 8-bit response frames |
0xA000:0F | Transmitted DALI 16 Bit Frames | Transmitted DALI 16-bit frames |
0xA000:0F | Transmitted DALI 24 Bit Frames | Transmitted DALI 24-bit frames |
0xA000:11 | Transmitted DALI 32 Bit Frames | Transmitted DALI 32-bit frames |
0xA000:12 | Transmitted backward Frames | Transmitted DALI 8-bit backward frames |
0xA000:13 | Erroneous Frames | Erroneous frames |
0xA000:15 | Collisions | Collisions Observe the information and notes in the chapters "Priorities" and "Bus timing" |
0xA000:16 | False Bittiming | A frame was received that deviates from the prescribed bit timing (including tolerance) and is therefore recognized as incorrect. |
0xA000:18 | Non DALI Frames | Non DALI frames |
