Read-on flags RO_xxx are used in the Read On field of the equipment declaration to specify when the read-out of an event occurs. These flags are defined in midas.h.
- Multiple flags can be ORed together, e.g. RO_RUNNING|RO_ODB.
- RO_TRANSITIONS is equivalent to RO_BOR|RO_EOR|RO_PAUSE|RO_RESUME.
| READ_ON Flag name | Value | Readout Occurs |
|---|---|---|
| RO_RUNNING | 1 | While running |
| RO_STOPPED | 2 | Before stopping run |
| RO_PAUSED | 4 | When run is paused |
| RO_BOR | 8 | At the beginning of run |
| RO_EOR | 16 | At the end of run |
| RO_PAUSE | 32 | Before pausing the run |
| RO_RESUME | 64 | Before resuming the run |
| RO_TRANSITIONS | 127 | At all transitions |
| RO_ALWAYS | 255 | Always (independent of the run status) |
| RO_ODB | 256 | Copies the event to the /Equipment/<equipment name>/Variables ODB tree. The ODB is updated with a new event approximately every second. Note that this feature is generally used only for testing or monitoring, as writing large amounts of data to the ODB takes time. |
