Amendment to Power Quality Meter Goes IEC 61850 and IEC 60870-5-104

The recent post "Power Quality Meter Goes IEC 61850 and IEC 60870-5-104" needs some explanation to understand what the Gateway could do.
In the case described in the post, we use one gateway for one power quality meter. Of course this is only one example. A single gateway can acquire signals from many power quality meters from different brands and via different protocols: Modbus I/O, Modbus/TCP, Profibus, ProfiNet, Ethernet/IP, and IEC 61850.
The gateway acts as well as a data concentrator, data manager, or proxy gateway. You may use it for any other signals - outside the power quality application. It may be connected to a substation LAN and tap GOOSE messages flying around.
The nice thing is: It can transform between (almost) ANY protocol without the need that IEC 61850 or IEC 60870-5-10x is integrated directly into the end device like a power quality meter.
In the future we will see more devices that have IEC 61850 integrated into their devices (by using a special piece of hardware or integrated onto the main controller of the device).
