[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=2 for
AIN blocks and IOMOPT=0 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
