Re: [foxboro] How to get Foxboro to capture some process data at each month endor year end.

Kashif,

> Is there a method to capture any process data say like in CALC block at
the end of each month or each year. I know we can capture data daily at any
time using "TIM" instruction in the CALC block.

You could link some integer inputs of your calc block to
CPNAME_STA:STATION.MONTH or CPNAME_STA:STATION.YEAR.  When one of these
changes you can capture your data if it is not to late to do so.

Otherwise you could write a shell script/c program (depending on number of
points you want to capture) and use cron (cron if you have a decent O.S. or
scheduler if you have a wannabe O.S.) to capture the data. Or even write a
report to get the information out of the historian depending on what you
want to do with the captured data.  There are some utilities on the
cassandra website that will collect C:B.Ps or access historical data.

If you can do it in a calc block do it in that.  Remember to obey the Laws
of Alex.
