Basics
Interbus
The Interbus system is designed as a data ring with a central master/slave access
procedure. Using the ring structure allows you to send and receive data simulta-
neously. The data travels through the ring in both directions via a cable. Each par-
ticipant in the InterBus system has an ID register (identification register). This re-
gister contains information about the module type, number of input and output
registers, as well as fault and other statuses.
Interbus is suitable for rapid, time-critical data transmission, as well as extensive
and complex communication tasks.
Anybus-S Interbus Fibre Optic Bus module
The Anybus-S Interbus Fibre Optic bus module is a complete interbus-S slave. It
contains all analog, digital and optical components of a powerful interbus con-
nection for transmission via fibre-optic cable. An integral microprocessor hand-
les all bus traffic.
The Anybus-S interbus Fibre Optic bus module is used for transmitting large
amounts of data with high data throughput and utmost reliability. Transmission
via fibre optic cable provides utmost protection against interference and ensures
a long service life without having to change the optic cables.
The Anybus-S interbus Fibre Optic bus module supports a maximum of 10 words
of process data, as well as the interbus baud rates 500 kbit/s and 2 Mbit/s. The
interbus interface design incorporates fibre optic technology, and is equipped
with FSMA connections according to IEC 874-2 and DIN 47258.
Device concept
The AB interbus FSMA interface includes a UBST 1 board with a piggy-backed
Anybus-S interbus Fibre Optic bus module. All the information required for an
interbus connection is stored on the CFM on the UBST 1 board.
