Re: [foxboro] OMI on DM

I use OMI a lot and have a similar problem where I have text content 
driven by .MSGNO and .SN000X parameters, but my problem is sort of the 
inverse of yours in that sometimes the content of the OMI message is not 
visible, but may become visible if the display is refreshed/updated, - 
sometimes, it doesent happen to all displays all the time. Its frustrating 
to the operations personnell to say the least. We have a plan to move away 
from the OMI driven message handling and move to a messsage handling 
system we built ourselves.
Regards,
Gabriel.

[foxboro] OMI on DM






Anybody out there using OMI (Operator message interface I believe it is 
called) from Invensys on a 6.3 unix system?
This OMI handles sendconf's from Sequence code and shows the sendconf's 
text on the display. It does not exist in Windoze

I have a problem with displays that show Strings, and discretes (text tied 

to Intgrs) on certain displays. When I call the display the strings and 
discretes are smurfed. When I refresh the display sometimes everything is 
ok, sometimes smurfed again. the smurfed objects show the correct strings 
and discretes, and seem to update ok, but the blue colour is anoying and 
gives the impression something's wrong....
When I delete the OMI message_ok object, the smurfing stops, the display 
looks ok everytime it is opened. When I import the message_ok again the 
smurfing starts again.

Strange thing is, it is only on certain displays, other displays work fine 

and have been working fine for ages using OMI. the problem persists on 
these problem displays and does not occur on any others

This OMI seems something exotic, I doubt if any of you use it but you 
never know, maybe someone at Invensys ever used it.....

Thanks & Rgds,

Dirk
