Re: [foxboro] foxboro Digest V9 #177

FoxRay can be tuned to gather data ie every 15 min, this only takes a few 
minutes max (fast collect)...... Every day there's a full upload (foxray 
calls this a slow collect). No stress on the system so far....
forget all about the classic upload stuff which takes ages........the data 
is collected and converted on the local station (boothost or any station 
hosting CP's, modbus etc)  and then pushed in a fast format to the dbse 
host. (if I'm not mistaken)
If we have a problem with batches, we can go back and search for operator 
actions to see if they made an error, which saves time and discussions, 
but offcourse you can also use the OAJ of the I/A for this.

Dirk,

"I mostly use it to track operator changes, (also FOXSELECT changes),"

Does this mean you regularly perform the UPLOAD function on your CP's?
What frequency? Or do you use a change tracking function that gets
advised on all operator changes and therefore does not look for changes
in the configuration database.

Most sites that I communicate with have 45 - 60 CP's that take an
average of 1 hour to complete the UPLOAD. They are reluctant to perform
an automated UPLOAD so they do them manually about once a month.
