Extensions for IEC 61850 System Configuration Language to describe HMIs have been proposed
The idea of the document- Communication networks and systems for power utility automation – Part 6XX: Configuration description language for communication in power utility automation systems related to Human Machine Interfaces (proposed IEC 61850-6xx) – is to describe how the common components found within HMI applications are to be described using the System Configuration Language, which are incorporated under IEC 61850- 6XX. These components include but are not limited to the single line diagrams; network topologies; toolbars; static/dynamic text; dynamic bus colouring; alarms and annunciations; user dialogue displays; static and dynamic colouring schemes; menus and navigation bars; etc.
It will define how the components found within HMI applications are to be described using the SCL.
It will outline basic principles that need to be considered when building the HMI application, and specify how the HMI’s graphical objects are to be declared in XML using a standardized data model. The future document is aligned with the fundamental concepts defined within IEC 61850 and builds upon:
- The configuration description language defined in IEC 61850-6,
- The basic communication structures defined in IEC 61850-7-4.
It may require revision to multiple parts of the IEC 61850 standard, including part 5 (possibly adding HMI communication requirements), part 7 (possibly adding new HMI data models) and part 10 (possibly adding HMI testing).
The deadline for comments is November 25, 2016. The document for review is available at IEC website.
