I don't have an answer for your speed difference question, but I do have
a suggestion.

Have you tried /opt/fox/bin/tools/setpars? It won't update the workfile
like the ICC Driver task does, but that seems to be okay for your
application.

Subject: [foxboro] FDSI blocks

Dear list,
 =


We are currently preparing a project which involves 6 serial modbus
interfaces through a number of FBM231.

 =


We have a fully equipped lab-system (nodebus AW51E, CP60, COM30 etc,
ATS,
FCP270, FBM231, terminal server etc).

This system holds only 1 FCP270 so all our preparations are loaded in
this
one CP (approaching the 4000 block limit (-: ).

For testing purposes we have a set_for_sim script which will set the
SIMOPT
to 1 for hundreds of FDSI blocks.

This is were my question relates to: the set_for_sim script is an ICC
script. With this script we notice that setting the SIMOPT for 1 block
takes
about 2 seconds so the complete script takes hundreds of seconds to
finish
(takes about 15 minutes to finish!)

The same script is used, on the same control processor, to set IOMOPT=3D2
for
AIN blocks and IOMOPT=3D0 for CIN/COUT & AOUT blocks and these are set in
an
eye blink !? =


 =


Why does setting a SIMOPT for an FDSI block take so much time?

 =


The fact that a CP270 normally does a check-point in about 10 seconds is
completely wasted due to this behaviour! (although I must add that I
don't
run the set_for_sim script that often so it's not really causing a
problem).

I'm absolutely NO FAN in regards to FDSI blocks, IMHO they are just not
finished and this only adds to the list of negative points concerning
these
blocks.

 =


Kind regards,

Patrick Martens
