- Foundation Fieldbus is a communication protocol that serves as a physical means of connecting intelligent devices, including temperature transmitters, pressure transmitters, and valve actuators.
- Fieldbus was developed by the Fieldbus Foundation. The physical layer complies with the specifications for fieldbuses established by ISA SP50.02 and IEC 1158-2.
- The technology known as fieldbus enables multiple intelligent devices to share a single communication link. A DC carrier is given a digital communication signal, which is then superimposed on top of it.
- This offers for greater flexibility for the addition of I/O ports in the future as well as reducing the number of terminations that are required to link all of the field devices to the host system.
- A device that uses Foundation Fieldbus is capable of addressing as well as storing and transmitting data.
- The devices have the ability to record values, monitor changes, and activate alarms based on previously established parameters.
- In order to set the values of a valve actuator, host systems are able to read transmitter variables such as temperature and pressure by using tag names that have already been predefined.
- The Manchester BiPhase-L algorithm is utilized for the encoding of digital signals, and the CRC method is utilized for error checking.
- There are two distinct varieties of devices that are compatible with Foundation Fieldbus: a Basic Device (BD), which can read inputs, monitor values, and set outputs if it is designed to do so; and an Advanced Device (AD), A Link Active Scheduler (LAS) carries out the same functions as a BD and coordinates the time of network communication amongst all of the active devices that are connected to the network.
