IEC 61850 engineering workflow

The following diagram illustrates the IEC 61850 engineering workflow and the role of Profile Studio.

1	Using EPAS-E, create an Electrical Application Scheme, including the necessary functions to be performed, and create communication networks with corresponding IEDs.
2	Export ICD files from Profile Studio and import them into EPAS-E. Link the Electrical Application Scheme Functions with the available IED Functions and configure the dataflow between the IEDs.
3	Export SCD files from EPAS-E and import them into Profile Studio. Now the IEDs know their role, as described in the SCD file, such as the electrical section they will manage and the data they will send/receive from other IEDs in different communication subnetworks.
4	Make local changes to IED configuration and export from Profile Studio as IID files. This helps to maintain a consistent Single Source of Truth for overall system configuration.
5	After configuration of an IED is complete, download the configuration to the IED. A proprietary format is allowed, though a SCL-based CID file is recommended for easy maintainability.
