[foxboro] FBM 224

I have seen some traffic on the list concerning FBM 224's recently, so
maybe someone has experienced the same problem.
 

We have an FBM 224 talking to ControlLogix via a Prosoft module.  We
have had a couple of occasions where the communications have dropped
out.  Of course all of the points that are coming in over the Modbus
link "smurf out".  The problem is that some of the points do not come
back.  They remained smurfed and have a W69 - Unvresolved connection

 

The only way that we have been able to resolve the connection has been
to "Delete Undelete" the points. 

 

TAC's response was to submit a CAR, which we will do, however I was
wondering if anyone has experienced this and have any ideas.

 

Thanks,
