Missed totalizer outputs

Hi everybody,

I have a DCS integrator tag. This tag accumulates the energy generated by a solar plant. I need to create a tag that calculates the energy generated each hour. For that purpose I've defined a Totalizer tag with this configuration:

Totalizer Point Attributes for: in_tot
Descriptor: IN Totalizer

archiving = 1
calcmode = EVENTWEIGHTED
compdev = 2
compmax = 28800
compmin = 0
compressing = 0
compvalue = 
conversion = 1
datasecurity = piadmin: A(r,w) | piadmins: A(r,w)
descriptor = IN Totalizer
engunits = MWh
eventexpr = 
excdev = 0
excmax = 0
excmin = 0
filterexpr = 'OP_MODE_filtered' = 0 and 'test_mode' = 0
function = TOTAL
movingcount = 1
offset = +0H
offset2 = +0M
options = INFROMTOTALIZER UNDERISZERO ONEATEND 
pctgood = 85
period = +1H /c
period2 = +2M
ptsecurity = piadmin: A(r,w) | piadmins: A(r,w)
ratesamplemode = NATURAL
reportmode = PERIODEND
scan = 1
shutdown = 0
sourcetag = in
span = 999,9
step = 1
tag = in_tot
totalclosemode = CLOCK
typicalvalue = 0
zero = 0
zerobias = 0

It seems to work fine. It processes correctly the source tag resets. But I noticed that it has missed some outputs and I don't know why. I have studied the source tags values at the hours of the missed outputs, and I saw that in these cases the next samples after the hour were "Bad Input". Here an example (09:00 sample missed):

Source Tag Values:
