FOUNDATION Fieldbus. FOUNDATION Fieldbus (FF) is the most widely deployed advanced fieldbus protocol, with millions of FF instruments installed worldwide. Its communications structure differs from PROFIBUS PA as it is peer-to-peer.
Foundation Fieldbus, Modbus, and HART. It appears that Fieldbus and modbus are RS232/485 based and HART is a digital signal riding on top of the 4-20mA analog signal, but which must be accessed via a modem type device.
However, any addition of FOUNDATION fieldbus requires either FOUNDATION fieldbus input/output, or an interface to a protocol supported by the legacy control host. FOUNDATION fieldbus compatibility to 4–20 mA control hosts is “FAIR”. Modbus defines an protocol "Modbus ASCII Frame Format". If we implement this protocol over RS-485 serial link to control RTU. Then over here RS-485 physical link can be considered as fieldbus ? Modbus is a popular fieldbus that allows a lot of data to be transferred, and supports two-way communication for remote operation (such as device programming and set-up).
Field and Bus make Fieldbus. A field is a geographically limited area. In an engineering world, it is intellection of the plant levels. Fieldbus is simply a means of communicating with input devices (sensors, switches, etc.) and output devices (valves, drives, indication lamps etc.) without the need to connect each individual device back to the controller (PLC, Industrial PC etc.). A protocol is a set of rules governing communications.

While the master is in charge of control of the processes, the slave stations work the individual partial tasks. Fieldbuses differ according to their topology (star, line, tree or ring), their transmission medium, and -depending on the type - different transmission protocols (message-oriented procedure or summation frame procedure). Serial fieldbus connectivity A classical fieldbus system only uses twisted pair connections to communicate over serial protocols. Compared to systems wired without fieldbus connections, serial fieldbus connectivity has a higher cost of components.

The master has full control of communication on the bus, whereas a slave will only respond when spoken to. The master will record outputs and read in inputs from each of its slaves, during every cycle, as shown in … The profibus and Modbus are enhancement to previous interface standards. These protocols defines real time communication between masters of bus, distributed sensors and actors. They are used for low transmission volumes and low latency applications.
