Fig. 9-52 Slave axis CBP address 12
Fig. 9-50 shows the hardware configuration. The left converter (drive
unit), the master axis "dispatcher" (on it the virtual master axis is
calculated) has PROFIBUS address 11. The right-hand converter,
"transceiver" (it reads the position setpoint, i.e. the value of the virtual
master axis from the "dispatcher") has address 12.
The additional six words to be sent (KK817, KK820 and K255) are
routed to the bus from the "dispatcher" as the actual value. This is
shown in Fig. 9-51 under slot 7.
They are the
n
read by the "dispatcher" itself via slave-to-slave traffic
(Fig. 9-51 Slot 8) and by the "transceive
r
" by slave-to-slave traffic (Fig.
9-52 Slot 7).
Via slots 4 to
6 (Fig. 9-51 and Fig. 9-52) PPO type 5 is emulated in the
two converte
rs.
