Fieldbus overview
Fieldbus Industrial boardsComputer buses that support industrial specifications vary among industrial applications. Fieldbus is one of industrial bus standards. Various products that support this standard are available. Fieldbus industrial communications computer boards are one of the devices. Fieldbus industrial communication boards are used in industrial communication networks. These connect the computers and programmable logic controllers (PLCs) fieldbus industrial network. These devices allow serial communication among industrial computers and other products offering both input and output functions.
Fieldbus Networks
Most (if not all) the industrial applications use measurement and control devices. Therefore fieldbus networks are implemented for applications such as SCADA or DCS (distributed control system) that use intelligent measurement and control devices. The communication links between the devices are two way digital and multi drop. This means the operator can store a digital value to a device or change if required.
Fieldbus Industrial boards and other bus standards
Filedbus industrial communication boards can be inserted or attached to almost all other computer bus standards. For instance two devices using compact PCI within the system for processing or other purposes. Now you can attach fieldbus industrial communication boards to both systems. This will provide you fieldbus industrial communication among the devices. Besides Compact PCI these boards support industrial standard architecture (ISA) bus, peripheral component interconnect (PCI), PC / 104, PC / 104 – plus, serial communications standards (RS-232, RS-422, and RS-485), PCMCIA devices, and Versa Module Eurocard (VME).
Fieldbus Industrial boards and industrial bus standards
Primarily Filedbus industrial communication boards follow the standards IEC (International Technical Commission) 61158 and IEC 61784. Fieldbus industrial communication boards are used in many industrial networks. These include CANbus networks, AS-I (AS-interface), DeviceNet, Industrial Ethernet, Netbus, HART® protocol (a registered trade mark of HART communication), PROFIBUS® (a registered trademark of PROFIBUS international), and FOUNDATION fieldbus.
Fieldbus Foundation
Filedbus Foundation is an organization that offers regulatory control both basic and advanced typically for FOUNDATION fieldbus. Fieldbus foundation contains laboratories to check compliancy of the fieldbus products. The devices are tested and marked as "registered" if follow the exact specifications by fieldbus foundation. This not only improves the reliability of Foundation fieldbus devices and industrial communication boards, but also gives feasibility in designing and understanding fieldbus standards.
Fieldbus industrial communication board's Form Factors
Fieldbus industrial communication boards are available in form factors to support all the bus standards mentioned above. In fact the form factor of a fieldbus industrial communication board depends upon the form factor of the bus system it needs to be attached. Moreover Boards as standalone devices and external modules are also available.
