Short description
General
information
The bus terminals 170 BNO 671 00 and 170 BNO 671 01 are remote bus nodes on
the INTERBUS and are used for the connection of a remote bus branch that has the
same extension limits as a remote bus.
The branch interface module 170 BNO 671 00 operates with the protocol chip SUPI
2. The branch interface module 170 BNO 671 01 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), provided as RS 485
interfaces and 1 RS 485 interface for the remote bus branch. The incoming remote
bus is electrically isolated. The interfaces conform to INTERBUS standards (DIN
19258).
The voltage supply and I/O periphery (relay output, keys) are connected via an 8 pin
terminal block.
The operating status is displayed using 7 LEDs.
