Re: [foxboro] Need Clarity on ALMSTA

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.

Subject: [foxboro] Need Clarity on ALMSTA


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
