1. Introduction

1.1 General

Modern field bus systems, microcontrollers and communication networks have had a great influence
on automation systems and have resulted in greater flexibility, availability, and ultimately, a reduction
in costs.

The widespread use of PC-based control only became possible with the availability of field bus
systems. With increasing control unit performance, the classic field bus ultimately became the limiting
criterion for the entire system. It was therefore an obvious step to adapt Ethernet technology, which
provides high rates of data transmission in IT applications, to the field of automation.

EtherNet/IP™ (Ethernet Industrial Protocol) is an Ethernet-based field bus. This is an open standard,
which is administered by the users' organisation ODVA.

1.2 Bus modules

Specific bus modules are available as interfaces between the field bus system and the NORD system
bus or the NORD frequency inverter. A document exists for each module (Technical Information / Data
Sheet), which includes the technical data, as well as installation and configuration information
