# Menu menuOmsl This menu is used for the `OMSL` field of many output record types. It controls whether the record will fetch an input value from its `DOL` input link when processed, which is useful when it is part of a closed loop control algorithm. The `supervisory` state means the input link will not be used, `closed_loop` enables the input link. | Index | Identifier | Choice String | | ----- | ---------- | ------------- | | 0 | menuOmslsupervisory | supervisory | | 1 | menuOmslclosed\_loop | closed\_loop |
