Chapter 2 – Overview
Overview
This chapter contains a short description of the InterBus-S system and
the NIBA-01 Adapter Module, a delivery checklist, and warranty
information.
The InterBus-S
System
InterBus-S is an open serial communication standard for the sensor–
actuator level. The protocol is based on DIN 19245 Part 2 and itself
specified in DIN 19258. In the exchange of parameter data, InterBus-S
employs the FMS user interface.
Further information is available from the host controller documentation,
Phoenix Contact (http://www.phoenixcontact.com), and the INTERBUS
Club (http://www.interbusclub.com).
Topology
The physical transmission medium of InterBus-S is a twisted pair cable
(according to the RS 485 standard). The main bus – in InterBus
terminology, the
remote bus – may contain 32 segments, each
consisting of a cable and the device connected to it. The maximum
length of one segment is 400 m. Local branches (referred to as
installation remote buses and local buses, depending on branch type)
can be connected to the remote bus using so-called
bus terminals.
