Industrial Automation community has been adopting proprietary (or open) protocols (eg: - Modbus, Profibus, DeviceNet etc) for communicating with devices and most of them are based on serial communication. Industrial Ethernet is all about the usage of Ethernet protocols in industrial environment. I have uploaded an article here regarding basics of Industrial Ethernet and its implementation.

I am happy to announce the launch of Industrial automation software (IAS) portal . IAS is an attempt to accumulate the software aspects of industrial automation. IAS is the first web portal dedicated to software side of industrial automation. IAS portal registration is free. Major topics related to IAS are process automation, motion control, process control, factory automation, PLC, HMI, MMI, SCADA, robotics, vision systems, instrumentation, MES, MMI, OPC, IEC, specifications, protocol, RFC etc.
