Slow or Sampling Counters

Bliss counters controllers, which inherit from SamplingCounterController, can be used as slow counters. Typically, they are storage ring current, eurotherms, wagos ... Beside continuous triggered scans, a software timer loop is launched. The frequency of the software loop is driven by the common parameter sampling_time. The counter values registered are saved in a separate scan.

To be able to match synchronized counters and slow counters, we can use the epoch in software loop and epoch_trig from the musst. epoch_trig is the epoch time at each point start trigger. It is usually shifted by about 100 msec compared to epoch.
