Comparison between Foundation Fieldbus and Profibus

Foundation Fieldbus FOUNDATION Fieldbus is an all-digital, serial, two-way communications system that serves as the base-level network in a plant

When intelligent devices are not communicating or show abnormal status for any reason the DD file often get blamed first.

The sensors and actuators that are connected to the inputs and outputs (IO) of a Programmable Controller or PLC are

HART, an acronym for Highway Addressable Remote Transducer, is an open process control network protocol and was introduced in the

HART ADDRESSING HART addressing is of two types: polling address and unique identifier. Polling address is single byte and is also

HART COMMUNICATION LAYERS The HART protocol follows the seven-layer OSI (Open Systems Interconnection) protocol, although it uses only three layers:

INSTALLATION AND GUIDELINES FOR HART NETWORKS HART devices use the conventional 4–20 mA current signal cable path to send the HART

APPLICATION IN SCADA The technology used in HART is very useful for SCADA applications. Since HART supports digital process values,

Serial Communication Data Transmission Modes means transferring of data between two devices. It is also called communication mode. These modes

RS232 vs RS485 RS232 and RS485 are standards for data cables. To exchange data between nodes on a network, the most
