Description
Terminating
A connecting conductor or a bus system must be terminated with a terminating
resistor.
Topology
Bus
topology
(topology) refers to the structure for the interconnection of
multiple
devices via bus. The topology is essential for ensuring that the network is fail-safe
and for the performance and selection of suitable hardware.
We differentiate between physical and logical topologies:
the physical topology describes the layout of the network wiring,
the logical topology describes the data flow between the end devices.
Hi-O Technology
TM
bus
The
Hi-O Technology™ bus
(Highly Intelligent Opening) is a bus for the
connection
of electronic components (devices) in door systems. It is designed for
control of one door. The status monitoring and exchange of information
between individual devices take place via a CAN bus.
A central logic controller can be omitted, because each device has its
own control unit. For escape route technology applications, it is a
closed system with permanently assigned bus addresses.
All devices are interconnected via four-core cables. Conventional devices can be
connected via I/O boxes. Integration in
a building network (Ethernet) or the interaction of multiple doors takes place
via a gateway (e.g. an Ethernet gateway).
Stub
All components in a bus system are connected to a common data line via
stubs
.
Remote interface
A
remote interface
(interface with extended connection line)
is where the connecting cable is longer than 10 m.
Ethernet
Ethernet
is a data network (LAN technology).
Gateway
A
gateway
(e.g. Ethernet gateway) connects devices to the network.
