Industrial automation 4.0: the fieldbuses
These are digital communication systems increasingly used in automated production
The availability of extensive communications options is a standard requirement in almost all automation solutions developed today. In recent decades, giant steps have been made in the field of industrial automation and, in particular, as regards serial-type digital communication systems between field devices (sensors and actuators) and/or between automatic control devices ( PLC). This type of transmission is defined by fieldbuses.

The importance of Fieldbuses for communication between devices
Fieldbuses are, today, a constantly evolving reality. For this reason, the industry needs adequate support for the transport of increasingly large and complex data packets. The Fieldbus is nothing more than a distribution system supported by a local network, useful for guaranteeing communication between the various connected devices.
The development of fieldbuses in the industrial weighing sector

This need has also developed in the industrial weighing sector. “We are passing to weight indicators with Fieldbus because they allow to connect to the control PLC. – explains Gianluca Bassanelli, managing director of NBC Elettronica Group – From here the customer can directly develop his own management application“.
Fieldbuses, in fact, are very complex automated network protocol, which allow real-time controls of industrial processes.
“A single control over complicated processes has facilitated management – concludes Bassanelli -. The plants are increasingly bound to the use of PLCs, which today are developed on fieldbus“.
Fieldbus transmitters made by NBC Elettronica Group
NBC Elettronica Group, leader in the sector of Made in Italy industrial electronic weighing systems, has developed numerous transmitters and weight displays, fully customizable and interfaceable with the most varied fieldbuses.
Here some examples:
- Modbus RTU
- Modbus TCP
- Profibus DP
- Profinet
- Ethernet IP
- Ethernet
- EtherCAT
- DeviceNet
- CANopen
All the models offered are constantly evolving, an essential aspect to guarantee maximum performance, following the current regulations in this sector.

Each electronics equipped with a fieldbus is supplied with its own configuration file necessary to identify and manage the device within the network.
