1 Introduction
1.1 Instruction notes
The symbol "Attention" refers to actions that could lead to damage to hardware or software or damage to
persons.
Conditions are listed here that you must comply with for correct operation. The symbol "Hand" refers to
tips and advice for efficient use of the device and for reducing additional work.
The symbol "Text" refers to further information sources (manuals, data sheets, etc.). This symbol also
helps you with better orientation in these instructions.
1.2 General information
This InterBus documentation is valid for the device series NORDAC trio SK 300E, SK 5xxE and SK
700/750E.
The respective SK 300E, SK 5xxE and SK 700/750E basic devices are delivered with a dummy cover for the
technology box slot. The basic models do not have any components for parameterisation and control. To be able to
establish communication via the InterBus, an InterBus technology module must be used.
The InterBus interface conforms to the standards DIN 19258 and DIN 19245 Part 2.
1.3 Further Information
These instructions only describe the NORDAC IBS technology module. Further information can be found in the
manuals of Phönix Contact or, with reference to the drive profile, in the DRIVECOM user group.
All the frequency inverter parameters are described in the manuals BU 0300, BU 0500, BU 0700 and BU 0750.

1.4 The bus system
The INTERBUS {xe "INTERBUS field bus system"} open field bus system provides standardised connection of all
process peripherals with all common controllers.
The InterBus is a very efficient bus system which works according to the special master-slave access method, also
referred to as the summation frame protocol. This total frame enables a constant bus cycle.
From a topological viewpoint, InterBus is a ring system, where send and return circuits are sent via every
subscriber. This ensures full duplex operation.
The NORDAC SK 700E and SK 300E can be connected to other sensors/actuators via a serial bus cable. InterBus
differentiates generally between remote bus subscribers (this module) and local bus subscribers that derive as sub-
ring systems from the remote bus.
In general, two different data transmission channels are used, the process data channel and the parameter data
channel, and both are supported by this access module.
In each data transmission cycle, a data volume of 3 to 5 words of 16 bit each are transmitted.
