DigiGate Profibus

INSTRUCTIONS MANUAL - V1.0x B

INTRODUCTION

DigiGate Profibus is the ideal equipment for interconnecting a Profibus DP network with a Modbus RTU network. It

Works as a gateway, operating as a master station in the Modbus network and as a slave station in the Profibus network.

Thus, according to its previous configuration, DigiGate will read the data of the other devices (slaves) of the Modbus

network and send the read values to the Profibus master. In the same way, it will write at the output of the Modbus

slaves according to the Profibus master requests, providing a complete control of the Modbus network devices through

the Profibus network.

The data interchange is performed through internal memory tables of the device, which are shared between the Profibus

side and the Modbus side. This data interchange mode is very simple, since the Profibus control system will only need

reading the data from the reading table, which is continuously fed and updated through the reading operation performed

by the Modbus. In the same way, the Profibus will write the data in the writing table so that the Modbus can forward the

new values to the correct registers of the corresponding slaves.

The device is totally configurable through the application DigiConfig for Windows®, which comes with the product,

making access and change of its parameters really easy.

This manual will present the instructions necessary for installation and connection of the module. The installer for the

DigiConfig is contained in the CD which comes with the product. The installer program can also be found at the

manufacturer’s homepage for download.
