Ethernet bus for data communication between controllers, (CADI), Lobby
Vision, e-Vision and BMS
– It is also used alternatively to connect the PORT technology gateway
(PTG)
– This network is exclusive for group communication and will not be
shared with other uses
– Ethernet bus with TCP/IP protocol
– E-Vision 5 and Lobby Vision 3 connected through OMS protocol
– Maximum number of nodes required by this architecture is 18
(up to 8 on CPUCF, 1 in Lobby Vision, 1 in BMS and up to 8 in e-Vision)
– If PTG is connected to the Ethernet, the required number of nodes grows
to 26
– Cables between lifts and Ethernet switch are deployed as part of the MR
wiring, IP address scheme based in 0-config
– PTG shall include a firewall between group network and PTN
– Ethernet switches are kept alive with emergency power supply if lift main
switch is disconnected.
