IEC Just Published IEC 61850-80-5 Guideline for Mapping Information Between IEC 61850 and IEC 61158-6 (Modbus)

IEC TC 57 Just Published IEC 61850-80 -5 Guideline for Mapping Information Between IEC 61850 and IEC 61158-6 (Modbus)

(57/2250/CD, 166 pages) - closing date for comments: 2020-09-11

Excerpt from the introduction:

"This technical specification provides a guideline to exchanging information between IEC 61850 and IEC 61185-6 (Modbus TCP). Nowadays, industrial field such as distributed energy resource (wind and solar energy, etc.) and condition monitoring, has been exchanging the information from Modbus to IEC 61850 for an effective operation. Although many manufacturers already implemented the Modbus to IEC 61850 conversion device or system, these devices do not guarantee interoperability. Therefore, it requires the consistent and unified information exchange scheme between IEC 61850 and IEC 61158-6 (Modbus).
Modbus over serial line (Modbus RTU) is not part of IEC 61185-6, but is also considered in this technical specification."

HMS Smart Grid Gateways Are Now IXXAT SG Gateways

The HMS Smart Grid Gateways (supporting a wide range of standards like IEC 60870-5-104, IEC 61850, Modbus TCp/IP, ...) are now marketed by HMS under the HMS brand IXXAT Energy SG Gateways.
IXXAT SG-gateways... 

• enable easy remote control and management of electrical systems
• allow to log and display application data and energy consumption
• provide IEC61850 client/server (publisher/subscriber) and IEC60870-5-104 client/server support
• have in-built Modbus TCP client and Modbus RTU Master interfaces
• provide connectivity for I/O, M-Bus, PROFIBUS, PROFINET and EtherNet/IP based devices

New Gateway for EtherNet/IP from and to IEC 61850, DNP3, IEC 60870-5-104, ...

The Anybus® SG-gateway is designed to specifically target Demand Response (networking of industrial electric loads) and Virtual Power Plants (networking of energy resources like biogas plants or combined heat and power units) applications.
REMOTE TERMINAL UNIT FOR SMART GRID APPLICATIONS
The SG-gateway with EtherNet/IP implements a real-time EtherNet/IP adapter interface with an integrated 2-port switch, allowing seamless network integration regardless of network topology (line, star, bus).

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.
