TIMSTATEDAT| 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 |
updated on each action on the General Timing Windowmodified 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. |
