1. Introduction

Thank you for choosing MJK PROFIBUS communication module. We have
done our outmost to design and manufacture a high quality product that
should satisfy your requirements.

The MJK modem and communication modules is easy to install in MJK Mag­Flux, SuSix and Oxix units and to put into service. However, read this manual
first to learn more about the specifications, how to install and how to operate
the equipment.

The equipment must be handled and operated as instructed by the manufac­turer, MJK Automation ApS, to ensure stable operation.

The MJK modem and communication modules can be obtained in several dif­ferent versions supporting standard communication types and protocols like
PSTN, GSM, GPRS, RS 232, RS 485, Modbus RTU, Profibus PA and Blue­tooth. This manual covers Modbus RS 485.

You can always contact your local representative or the MJK hot line for
advice and guidance:

1.1 MJK Profibus Communication Overview

Profibus

The Profibus communications module is transporting information from the
individual MJK instrument such as Magflux.

The firmware of the display unit will automatically recognize the mounted
communication module, and configuration menus will automatically be visible
allowing connection to a PLC unit and other units.

Profibus is also creating a simple way of connecting up to 4 MJK instruments
in a rapid communicating network, without additional equipment.
