New Work Proposal: IEC 61850 – Modbus Mapping

The Korea Electrotechnology Research Institute (KERI) has proposed a new work item: Guideline for mapping information between IEC 61850 and IEC 61158-6 (ModBus).

Document: 57/1434/NP
Closing date for voting: 2014-04-25

Quite interesting proposal!

We conducted yesterday (during a Workshop at Beck IPC in Wetzlar/Germany) a very easy tool to map between Modbus, IEC 60870-5-104, IEC 61850, … using a graphical webbased configuration tool needs just a web browser:

1. Topology for mapping between Modbus and 104:


Signals (Inputs and Outputs) that can be used by the WEB PLC:


Available communication solutions (Modbus, IEC 60870-5-104, IEC 61850, OpenVPN, …):


Function chart of objects and simple logic:


The interest in such a simple solution that does not requires any programming – except drawing lines between input/outputs, functions and outputs/inputs – is very high. Wrappers are available to integrate C/C++ or CoDeSys programmed functions (Function Blocks).

The IEC 61850 information models are interpreted and the PLC inputs and outputs are automatically generated and shown as a tree …


Finally we demonstrated a Gateway: Process –> Modbus and other I/Os –> IEC 61850 –> IEC 60870-5-104 (DNP3):


The IEDs com.tom BASIC 3.1S (with 5 Port Ethernet Switch and second Ethernet Port integrated) and BASIC 5.1 have been used for the system (process, process monitoring and control, gateway and CC communication).

A second Workshop in German will be conducted on March 12, 2014. The first Workshop in English is scheduled for March 13, 2014.
