Dominic,
For AIM products like AIM Historian , AIM OPC Server
Look at /opt/aim/bin/aimapi.cfg
Do you have a line in there like;
fastest_rsr = 10 ( means 5 seconds)
For 3rd party products like OSI PI , Aspen , etc
Look at /opt/fox/ais/bin/foxapi.cfg
Do you have a line in there like;
fastest_rsr = 10 ( means 5 seconds)
Without fastest_rsr configured theread scan rate defaults to 500 msec
for all reads to CPs/IGs.
Regards,
Scott

Subject: Re: [foxboro] OM scan load
The historian has been restarted. I did not notice any significant drop in
OM scan load with the historian stopped. There is a third party application
that pulls information via OPC. When that application is stopped their is a
drop in OM scan load. That application has been in place for sometime
without any changes. They have 5 stations displaying data from the CPs.
Unfortunately I am not familiar with the OM tools. One of the FCPs I didn't
make any changes on and the OM scan load has still been going up. Total
connections , tlcons is 0.

I hope this is not a silly question but did you stop and restart the
historian? Scan changes are only made on restart.
When you stop the historian does the OM load go down?
Is there any other application running? Can you turn it off briefly and see
if the OM load on the CP's goes down?
Howmany WP's are displaying data from the CP's? Can you place them all on
their Initial_Display, even briefly and check the OM load to see if it goes
down? Also check the Station display to see if the number of OM connections
goes down. If you know how to use the OM tools, they could help evaluate to
see if some "old" connections are hanging around when they should be
deleted. With all WP's on Initial Display, you should not see the WP
letterbugs in the list from the OM tools.
