Fieldbus is a digital communication standard used for exchanging signals between field devices (such as measuring and control instruments) and controllers in environments like factories. Compared to conventional analog signal transmission, fieldbus offers the following advantages:
- With just a single pair of cables, you can access signals from multiple devices or multiple pieces of data within a single device.
- At the controller or receiver, A/D (analog-to-digital) and D/A (digital-to-analog) conversions are unnecessary, allowing for more accurate signal transmission.
- Since dozens to about a hundred devices can be connected to a fieldbus, wiring costs can be significantly reduced.
- There is increased flexibility for system changes or expansions.
- In addition to data communication, fieldbus also allows for wider applications such as device data transmission and calibration.
