| DAFNESTATE_JDAT | General Timing Window: it fetches from the DEVIL387 the GTIMDyn global and combines some of its data with information obtained from the Timing Status Word register. The result (GTIMStatusData) is translated as a Json document and written to Memcached on:
- "Apply Sequence" command;
- "BTF RUN" command.
| ~0 | ~250 | ~0 | The key content is a Json document with the following format.
{
"bunch_seq_1_32":0,
"bunch_seq_33_64":0,
"bunch_seq_65_96":0,
"bunch_seq_97_120":0,
"accumulator_pulses":0,
"linac_freq":0,
"extraction_freq":0.0,
"equidistant":0,
"mode":0,
"execution":0,
"standby_state":0,
"run":0
}
Values for the various fiedls are as consistent as possible with the "Timing Status Word" corresponding bitfields. In some cases the representation is modified in order to make it more intuitive (e.g. mode: -1=electrons, 1=positrons) or even directly usable (e.g. linac_freq: 25 Hz, 50 Hz). In other cases (execution, stand_by_state) the value is equal to that of the corresponding bitfield in the Timing Status Word register (see table below). - bunch_seq_1_32, _33_64, _65_96: number in the range (0-4294967295)
- bunch_seq_97-120: number in the range (0-16777215)
- "accumulator_pulses": integer number
- linac_freq: 25.0, 50.0 [Hz] floating point
- extraction_freq: 0.2, 0.5, 1.0, 2.0 [Hz] floating point
- equidistant: 0=contiguous, 1=equidistant
- mode: -1=electrons, 1=positrons
- execution: 1, 2, 4, 8, 16 (see table below)
- standby_state: 1, 2, 4 (see table below)
- run: 0=standby ,1=run
| The Json key is worked out by a SubVI of the General Timing window: /u2/dcs/source_solaris/0_classes/TIM/console/timing_2/General_Timing_3.3.3.vi - build 20230125-1145. The SubVI is:  Image Added/u2/dcs/source_solaris/0_classes/TIM/console/timing_2/TimingStatusDecode.vi
(There is also another version named "TimingStatusDecode2.vi" that represents the DAFNE fill pattern as a unique sring of 120 "0" or "1" characters). The key is updated any time a user issues "Apply Sequence"or "BTF RUN" from the General Timing window. |
