Create a Relay Function and Add It to a Protection Relay - Intergraph Smart Electrical - Help - Hexagon

You create relay functions in the Reference Data Explorer.After a relay function exists in the Reference Data Explorer, you can add it to a protection relay in your plant. Each relay function represents a default action in response to a standard setting. After adding a relay functions to protection relays in the Electrical Index, you can modify the function parameters. Also, it is possible to associate a relay function with a custom symbol, place a relay function on a composite drawing, and associate an auxiliary graphic with a relay function.
