Option Profibus

Introduction

The stereoscopic width measurement gauges DigiScan XD4100 with the option Profibus-DP adds a Profibus DP connection

Physical connection

The physical connection to the Profibus-DP fieldbus is achieved using two shielded twisted pairs

Connectors

The gauge supplies two additional M12 connectors to link with the fieldbus Profibus-DP.

Note

The Profibus-DP serial link is galvanically insulated from the 0V

Terminating resistors

• ONLY ONE XD GAUGE ON THE PROFIBUS-DP SEGMENT

  • Connect the twisted pair from the gauge’s PROFIBUS IN to the master

  • Connect the external terminating resistors to the gauge’s PROFIBUS OUT connector

  • The master should have its own terminating resistors

• XD GAUGE IN LAST POSITION ON THE PROFIBUS-DP SEGMENT

  • Connect the twisted pair from the gauge’s PROFIBUS IN to the previous sensor

  • Connect the external terminating resistors to the gauge’s PROFIBUS OUT connector

  • The first device should have its own terminating resistors

• SEVERAL DEVICES ON THE PROFIBUS DP SEGMENT

  • Connect the twisted pair from the gauge’s PROFIBUS IN to the previous sensor

  • Connect the twisted pair from the gauge’s PROFIBUS OUT to the next sensor

  • On the first device, connect the external terminating resistors on the PROFIBUS IN connector

  • On the last device, connect the external terminating resistors on the PROFIBUS OUT connector

Caution

The bus must start and end with terminating resistors in order to prevent signal reflection

Configuration

Profibus address

Note

The default Profibus slave address is set to 7 and can be changed in the gauge setup

GSD file

A GSD configuration file is supplied with the product on the gauge’s network drive at the path : /documentation.

Hint

It can also be downloaded on the deltasensor website

Source selection

Important

Select the Profibus to be the field bus of the speed, temperature and digital inputs in the gauge setup

Data exchange

Data will be transmitted in big endian (M)

Input data

Note

3x registers, input registers : Measurement data (gauge slave -> master)
