Short description
General
information
The branch interface module 170 BNO 681 00 is a remote bus node on INTERBUS
and is used for the connection of a remote bus branch that has the same extension
limits as a remote bus.
The connection of the remote bus line uses fiber optic technology.
The branch interface module 170 BNO 681 00 operates with the protocol chip SUPI
3 and supports the entire diagnostic function of the Generation 4 INTERBUS
firmware.
Mechanical
construction of
the branch
interface module
It has two interfaces (incoming and outgoing remote bus), with fiber optic interfaces
and one RS 485 interface for the remote bus branch. The interfaces conform to
INTERBUS standards (DIN 19258).
The voltage supply and I/O periphery (relay output, manipulator) are connected via
an 8 pin terminal block.
The operating status is displayed using nine LEDs.
