[foxboro] Setting Application Objects from IND blocks

We are working on a DMCplus application where we have to set the values
of Application Objects, which were generated by DMCBridge, using an IND
sequence block.  We are noticing a great deal of latency, upwards of 1
or 2 minutes, between the time the IND sequence code runs and when the
Application Object value gets set.  Here is an example bit of IND HLBL
code:
 

IF value1 > value2

            :APP_OBJ_CMPND:APP_OBJ.PARAM := value3;

ENDIF

 

Is this fairly typical of IND sequence code performance?  Is there
something special about Application Objects vs. regular CP blocks that
might cause this?  Is there a setting somewhere that maybe we have left
at the default that governs how fast AO's can be written to?

 

Any ideas would be appreciated.

 

Thanks,
