I need an audible alarm to sound and a message to display in the message area when the following are true:

BLR-SP-104A.MV > 50
AND
BLR-PI-104A.PV <= BLR-SP-104B.MV-2
AND
BLR-ST-104B.PV <> 12

Can someone out there tell me step by step how to do this? I have about ran myself crazy trying to figure this out!

All help is greatly appreciated.

 

From what i understand of your question, my response is as below:

Goto Annunciation builder, define an annunciation tagname and a suitable message, Save, and exit.

In your control drawing, place a calcu block and add the following code:

ALIAS ANN {%AN001.PV.L} ! assuming u had chosen annunciation message 1
alias TAG1_MV BLR-SP-104A.MV
alias TAG2_PV BLR-PI-104A.PV
ALIAS TAG3_MV BLR-SP-104B.MV
ALIAS TAG4_PV BLR-ST-104B.PV

IF TAG1_MV > 50 AND TAG2_PV <= TAG3_MV-2
AND TAG4_PV <> 12 THEN
ANN1=1
END IF

For generate audible alarm message you should t&#1086; create Announcator and turn it when conditions are match.
