1. Bit L length defines the length of the packet to send 0 2 byte DALI packet 1 3 byte DALI packet Field TP transmit priority defines the priority of the DALI packet DALI single master systems do not need this field it can always be set to zero there Valid values are O highest priority to 4 lowest priority The priority defines the minimal bus idle time after which the packet is allowed to be sent to the DALI bus see field RP in table 4 2 3 Part 1 of the Nema standard 5 specifies how to use the different priorities When other DALI masters cause a lot of traffic on the DALI bus the terminal might not be able to send DALI packets According to the DALI access rules this affects especially packets with low priority In this case the terminal discards the packet automatically after 200 ms the Interbus master does not need to clear this ex plicitly The output process data word OUT2 is used as mirror to IN2 to acknowledge packets received on the DALI bus The next chapter describes this mechanism When the input buffer is explicitly cleared OUT2 has to retain the most recent acknowledge value Input process data word IN2 pas 14 13 12 11 10 9 8 7 6 5 la 3 2 1 Jo timestamp ofpacketinms 3 timestamp of packet in ms Table 4 2 2 6 Structure of input process data word IN2 in DALI mode Input process data word IN3 DALI data byte 2 RD2 DALI data byte 1 RD1 Table 4 2 2 72.

4. timebase is running over after about 16 s and starts again with 0 A change in IN2 indicates a new packet The terminal sends consecutively all received DALI packets with increasing index to the Interbus master without waiting for immediate acknowledge To this end the packets are stored in a separate four stage ring buffer A packet that is acknowledged by the Interbus master is deleted from this buffer when it is the oldest packet When the terminal detects that an acknowledge got lost that is the terminal receives an acknowledge for a packet that is not the oldest one it ignores this acknowledge and starts to send the packets again beginning with the oldest packet When no new packets are available that is all packets have been successfully acknowledged the terminal continues to send the last acknowledged packet in IN2 The Interbus master has to acknowledge incoming DALI packets by mirroring IN2 in OUT2 This acknowledge mechanism runs in DALI mode TYP 1 completely independent of the other output process data words For instance a change of OUT2 does not cause a remaining send command pattern in OUT1 to be processed again by the terminal So for incoming DALI packets the Interbus master has to a acknowledge all incoming packets for the terminal b drop duplicated packets for the Interbus master application Task a is simply done by copying IN2 to OUT2 Task b is done by dropping all packets that do not have an increa
