Fieldbus for PLC
Industrial automation 4.0: fieldbus systems
These are digital communication systems increasingly used in automated productions
The availability of wide communication options is a standard requirement in almost all automation solutions developed today. In recent decades, significant strides have been made in the field of industrial automation and, in particular, regarding serial digital communication systems between field devices (sensors and actuators) and/or between automatic control devices (PLC). This type of transmission is defined by fieldbus (FIELDBUS).
The importance of Fieldbus for communication between devices
The fieldbus is, to date, a reality in constant evolution. For this reason, the industry requires adequate support for transporting ever larger and more complex data packets. The Fieldbus is nothing more than a distribution system supported by a local network, useful for ensuring communication between the various connected devices.
The development of fieldbus systems in the industrial weighing sector
This need has also developed in the field of industrial weighing. “The shift to fieldbus weight indicators is taking place because they allow for connection to the control PLC.” – explains Gianluca Bassanelli, managing director of NBC Elettronica Group – “From here the customer can directly develop their own management application.” The fieldbus, in fact, are very complex automated network protocols that allow for real-time control of industrial processes. “A unique control over complicated processes has facilitated management.” – concludes Bassanelli – “Plants are increasingly bound to the use of PLCs, which today are developed on fieldbus.”
Transmitters with fieldbus produced by NBC Elettronica Group
NBC Elettronica Group, a leader in the field of industrial electronic weighing systems Made in Italy, has developed numerous customizable transmitters and weight displays, which can interface with various fieldbus systems.
Here are some examples:
- Modbus RTU
- Modbus TCP
- Profibus DP
- Profinet
- Ethernet IP
- Ethernet
- EtherCAT
- DeviceNet
- CANopen
All the models offered are in continuous evolution, a substantial aspect to ensure maximum performance, following the current regulations in this sector. Every device equipped with a fieldbus is supplied with its own configuration file necessary to identify and manage the device within the network.
