Industrial Ethernet for MAC

 
Industrial Ethernet is the name given to the use of the Ethernet network protocol in an industrial environment, for automation and process control.
 
A number of techniques are used to adapt the Ethernet protocol for the needs of industrial processes, which must provide real time behavior.
 
By using non-proprietary protocols, automation systems from different manufacturers can be interconnected throughout a process plant.
 
Industrial Ethernet takes advantage of the relatively larger marketplace for computer interconnections to reduce cost and improve performance of communications between industrial controllers.
 
Industrial Ethernet (IE) components used in plant process areas must be designed to work in harsh environments of temperature extremes, humidity, and vibration that exceed the ranges for IT equipment intended for installation in controlled environments.
