Hi Douglas,
We also had a similar problem with our historian reduction groups. TAC
logged in to our system, found bad points, and helped me fix it. After
removing the bad points, the reduction group worked ok. Actually, on our
system, the reduction group did not appear to be working, but it was.
Although new points would not appear in the in the reduction group
configurator, I could type in the C:B.P and the new point would be added. I
know it worked, because the new block description appeared when I hit enter.
And the new points worked in trends and reports. The new point would still not
show up in the reduction group list.

Hi list,
We are experiencing a problem with our historian. For some unknown reason,
the historian reduction groups are not working. So far we have taken the
following actions to no avail:
- Rebooted the AW
- Stopped and started the historian (in our case named FKHS01) via the
historian scheduler
- Stopped and started the reduction groups
- Stopped and started the reduction groups via the "clr start" option. The
first time we tried this option, we got an error message(error code -8),
which we haven't got in other tries of the "clr start" command.
After all these actions, the historian reduction groups do not work.
I would appreciate if anybody has an insight into this kind of problem.
Regards,
Douglas Navarro
