FUNDAMENTAL KNOWLEDGE IN COMMUNICATION NETWORKS

There are many technologies and many solutions of communication techniques to exchange data between the machines and between the devices by using networks. The complexity of networking leads to take in consideration different level or different points of view. ISO layers help to get some clarification about, by isolating different well identified functionalities.

The first part of this folder is a selection of general informations, of technical papers and educational papers related to the digital networks. They all concern the fundamental knowledge in digital communications need to exchange data ( protocols, standards, hardware and more ).

The second part is related with the specific features of the industrial networks dedicated to factory automation and process control. It introduces the main guidelines we can meet in most of the industrial networks solutions.

This directory lists all which concern computing and communication in general ( it is not industry oriented ). It concerns the transmission media, the networks ( essentially Ethernet based ), the programming languages, the peripherals, the interfaces and the operating systems. The standards resources you will get are in relation with digital networking, communication protocols ( NTP Network Time Protocol ), media ( ADSL, fibre channel ), networks ( Ethernet, IEEE 1394 ), internet standards ( HTML, javascript ). There are a lot of links reporting on Ethernet ( protocols, ports etc. ) and even graphical standards such as OpenGL ( Open Graphic Library ).

This introduction is a good synthesis reporting on factory automation and process automation fieldbus, with a short field bus history.

In the first part, Jonas BERGE ( ISA ) presents what are the digital networks and how specific are its industrial applications. The second part covers different applications areas of automation networking, such as factory automation, process automation, at field and host level. The evolution of control architecture section talked about PLC architecture ( distributed, centralized, field control system ), the fundamental differences between some field networks
