The function block has a few outputs dedicated for special purposes.
| Output | Description |
|---|---|
| CNF_CHANGE | Any setting change in the protection relay activates this output for a short period of time (100...200 ms). |
| GRPOFF | Some application function blocks do now allow unconnected analog inputs. In such a case, GRPOFF must be connected to such an input. |
| DEV_WARN | A protection relay's internal warning activates this output. For more information, see Warnings under the Self-supervision section. |
