This brings up a good point though.  Is there ANY documentation anywhere for
how to figure out these ALMSTA, BLKSTA, and INHALM bit extensions?  Could
somebody come up with something and submit it to Cassandra?  I don't have
the first idea how to do this, so a little primer would be nice.

        AND the mask 0030 hex with the high order bits of the alarm status
word.
        0030 just happens to be the High and Low Deviation alarm bits.

        Hello All,

        I have recently found a parameter extension I don't understand. I
have 
        been all through my Foxboro documentation and have searched the CSC
web 
        site to no avail. However, I am a little thick between the ears and
the 
        answer to my question may be right in front of me. I have a switch
block 
        who's toggle is connected to a real alarm block. The connection is:

         COMPOUND:BLOCK.ALMSTA.AH0030

        Can someone shed some light as to the AH0030 extension. I am
familiar with 
        using bit extensions but this extension baffles me. As I mentioned 
        earlier, I have been through the documentation. I had hoped that 
        Integrated Control Software Concepts B0193AW Chapter 8 - Block
alarming 
        would have answered my question.

        Thanks in Advance for any and all help.


        Regards,
        Dwight
