I have one more question, though I understand that it could be somewhat border-line.
The MIDAS state machine doesn't seem to have a state in between 'initialized' and

|
to plot time dependencies of the monitored detector parameters, say, voltages or temperatures,
one needs to convert the coresponging ADC readings into floats.

|
First of all it's important to understand that the slow control system has nothing to do
with events. So if you look at event statistics, these are the events with the slow control
data sent to the midas data file, not the history database. So the logging period (the one you
