Techniques for integration of intelligent electronic devices

An apparatus comprising a computer program operative, when executed, to:

• determine a template from a plurality of function unit templates based on a configuration of an intelligent electronic device (IED) in a first modelling language, wherein the plurality of function unit templates represents different types of IEDs and comprises variables for controlling and/or monitoring of a respective IED type in a form of one or more services, and wherein the template encapsulates template elements representing an application layer information model of the respective IED type in a second modelling language;
• fill the template based on the configuration of the IED by assigning values to the template elements based on the configuration;
• and
• create a function unit file in a third modelling language based on the filled template, wherein the function unit file is interpretable by a control application and comprises services encapsulated in the third modelling language.

A system, e.g., a control system, comprising:

• a control program and/or one or more peripheral devices comprising a function unit configured based on a function unit file to control and/or monitor one or more intelligent electronic devices (IEDs),
• wherein the function unit file is configured to be obtained by:
• determining a template from a plurality of function unit templates based on a configuration of an IED in a first modelling language, wherein the plurality of function unit templates represents different types of IEDs and comprises variables for controlling and/or monitoring of a respective IED type in a form of one or more services, and wherein the template encapsulates template elements representing an application layer information model of the respective IED type in a second modelling language;
• filling the template based on the configuration of the IED by assigning values to the template elements based on the configuration;
• and
• creating the function unit file in a third modelling language based on the filled template, wherein the function unit file is interpretable by a control application and comprises services encapsulated in the third modelling language.
