4.3.3 Slave Mode
The Slave movement has no network connection. It is synchronized with local time and monitored by a
Master movement (operating mode Unicast or Multicast possible). The cascade can help to reduce
wiring effort since only one LAN connection is required. The disadvantage is that the slave movements
cannot be addressed directly via a network connection. Monitoring is only possible via Master move-
ment. Power supply in the cascade is only possible through the Master movement (with PoE or DC
power supply). See chapter 5.1.
