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

Friday last week I was involved in installing a high level Power Quality Meter (UMG 512 from Janitza) to monitor the power for a new building:

The objective was to apply a smart gateway between the Meter and IEC 61850 and IEC 60870-5-104. It took some 90 minutes to install the meter and configure it for Modbus TCP communication. The gateway used is an HMS Anybus SG Gateway I/O.

The gateway offers connectivity to Profibus, ProfiNet, Ethernet/IP, and other protocols.
The gateway reads out 22 signals from the Meter (all new Meters from Janitza use the same addresses for the basic signals):

The Modbus signals (from an UMG 604) are listed in the gateway for polling:

As well we need to configure the Signals for IEC 61850 and IEC 60870-5-104:

The signals in IEC 61850 are configured with an SCL File. The 104 signals need manually configuration.

Finally we need to program the mapping from Modbus to IEC 61850 LNs and IEC 60870-5-104 signals. The drop-down menu is used to place the signals to the screen:

Finally the inputs are linked to the outputs:

The signals from the Meter are automatically exposed through IEC 61850 and IEC 60870-5-104 servers.
The IEDScout 4.1 from Omicron is used to connect to the IEC 61850 Server in the Gateway:

And the QTester104 receives messages from the IEC 60870-5-104 server:

Lesson learned: It took less than one hour to configure the Gateway and use it.
This is likely the easiest and fastest way to communicate Power Quality Meter signals through IEC 61850 and IEC 60870-5-104.
