Re: [foxboro] Foxapi delay

Opening and closing data sets is a slow process and it will be slower if any
points are missing.

Moreover, it is a process that "disturbs" every station on the network by
requiring them to examine the lists being opened to determine if they need
to reply.

So, my questions are:

1) Why do you open and close the lists?
2) What are you trying to do?

There may be a better way.

Subject: [foxboro] Foxapi delay

Hi, we are using foxapi calls in a C program....

scopen...
bwrite...
clsset...

Any time we run this program it takes 14 seconds for the three statements.
scopen uses read write access.

This time is normal???
Can we decrease this time???

Thanks in advance...

Miguel
