Products Description
Fieldbus is an industrial data bus that is the underlying data communication network in the field of automation. It replaces the traditional transmission of 4-20mA analog signals and ordinary switch signals with digital communication. It is a fully digital, bidirectional, and multi station communication system that connects intelligent field equipment and automation systems.
The fieldbus connects multiple devices through a single bus to achieve data exchange and communication between devices. Each device has a unique address on the bus, and data transmission is carried out through address recognition. The sending device packages the data into data frames and sends them to the receiving device through the bus. The receiving device determines whether to receive the data by identifying the address in the data frame. To ensure the reliability of data transmission, a verification mechanism, such as cyclic redundancy check (CRC), is usually used.
application
Fieldbus technology has formed a truly dispersed and complete control system on site, improving the reliability of control system operation and enriching the information content of control equipment. This has created conditions for controlling the entry of information into the public data network, communicating the connections between on-site control equipment and higher control management networks, facilitating the integration of control and control. At the same time, the combination of control network and data network facilitates the remote transmission of signals and remote automatic control in different locations.
type
PROFIBUS: A fast bus widely used in distributed peripheral components.
EtherCAT: A real-time Ethernet solution for industrial automation, with superior performance and easy use.
Lightbus: It has excellent EMI resistance, is easy to install, and has fast, cyclic, and deterministic data flow.
Interbus: Easy to configure, fast and reliable communication.
CANopen: By effectively utilizing bus bandwidth, shorter system response times can be achieved at lower data transfer rates.
ControlNet: An open standard fieldbus system that allows both cyclic and non cyclic data to be exchanged simultaneously through the bus.
PROFINET: A standard developed by PNO for open industrial Ethernet, which is an IT standard established internationally for communication.

FAQ
Q1: What is the difference between fieldbus and traditional connections?
A1: Compared to traditional connections, fieldbus systems allow many devices to share the same fieldbus line and send data to each other without the help of DCS controllers. This enables each device to perform certain functions, such as diagnosis, control, and maintenance, thus achieving a distributed control network.
Q2: What are the specifications of fieldbus cables?
A2: The specifications of fieldbus cables vary depending on specific applications and products, but typically include parameters such as conductor size, number of pairs, material and color of sheath, outer diameter of cable, conductor resistance, characteristic impedance, attenuation, electrostatic capacity, and estimated mass.
Q3: What are the standards for fieldbus?
A3: There are two types of fieldbuses on the market: standard and non-standard. Standard fieldbuses mainly include IEC61158, FF (Foundation fieldbus), LonWorks, Pro tibus, WorldFIP, etc., which are suitable for process control, manufacturing automation, and building automation.
