The Setpoint Table

The setpoint table (<corr>:CurrSetpt) can hold up to a maximum of 2000 values [can be increased but you'll need EPICS-3.14 to write large arrays]. It is possible to write less values than the maximum - EPICS will automatically know the number of elements that have been written to the setpoint table (this number is itself a read-only PV: <corr>:CurrSetpt.NORD). In particular, it is possible to write a single value to the table. The setpoint table supports Spear Timestamps (<corr>:CurrSetpt.TSE==-2) which means that it is possible to determine exactly when the first (and therefore all subsequent) setpoint was written out.
