Introduction

The UNIGATE

CX-CANopen (Mapping) - PROFIBUS DP module serves to adapt a CANopen

interface to PROFIBUS according to EN 50 170. In this application it acts as a gateway and

works as a CANopen with master functionality on one side and as a PROFIBUS DP slave on the
other side. It can be operated by any standard-compliant PROFIBUS master.

The module CX-C4Map-PB essentially consists of the following hardware components:

•

Electrically isolated RS485 interface to the PROFIBUS DP

•

PROFIBUS ASIC

•

Microprocessor 89C51RD2

•

RAM and EPROM

•

Serial interfaces RS232 (Service interfaces)

•

Electrically isolated interface to CANopen

•

Debug interfaces (for device configuration)

Conceptual

C4Map stands for CANopen with CANopen (mapping) functionality.

In the further course of this manual, the term "Fieldbus" is frequently used. In

these cases this applies to the PROFIBUS DP interface.
