The smoothing factor was set to 0.999 on all CPs. To confirm that the device is still active and responding and not in an "inactive state" (which happens if smoothing factor is set to its limit of 1.0), the LLCV trends over 30 days are posted for the seven CPs (CP3 excluded).

The smoothing factor algorithm (from EPICS integrated into Beckhoff):

if SMOO is 0 or INIT is True, VAL = val
else VAL = val * (1 - SMOO) + Previous_vale * SMOO

*this implements a first-order infinite impulse response (IIR) digital filter with z-plane pole at tau=-T/ln(SMOO), where T is the time between record processing
