Hi Tim, The following is from Integrated Control Configurator B0193AV, Rev L Steve Murray Asarco **************************************************************** Boolean Extensions to Status Parameters The format of Boolean connection extensions to status parameters is: Cname:Bname.Pname.Extension where: Pname = BLKSTA, ALMSTA or INHSTA Extension = [{0,1}.]{[~]Bmask,[~]{A,X}[H]mask,[~]symbol} Legend: [] = optional {,} = select one The following table lists examples of this type of extension. Pname.Extension Meaning BLKSTA.BAD Result = BAD Boolean of source BLKSTA. BLKSTA.~BAD Invert result of previous example. ALMSTA.LDA Result = LDA Boolean of source ALMSTA. ALMSTA.~LDA Invert result of previous example. INHSTA.HOA Result = HOA Boolean of source INHSTA. INHSTA.~HOA Invert result of previous example. BLKSTA.B12 Result = Boolean 12 of BLKSTA. BLKSTA.AH30A0 Bitwise AND the high-order 16-bits of BLKSTA with hex 30A0. If result not = 0, set result = 1. Else, set result = 0. Examples using the full Cname:Bname.Pname.Extension path name are: BLENDER1:PID.ALMSTA.LDA BLENDER1:MAIN.BLKSTA.AH30A0 -----Original Message----- From: Lowell, Tim: [mailto:Tim.C.Lowell@xxxxxxxxxxxxxxxxxx] Sent: Thursday, March 27, 2003 13:21 To: 'foxboro@xxxxxxxxxxxxx' Subject: Re: [foxboro] Need Clarity on ALMSTA 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.
