Not sure if this will work for your case but use a logic or calc block, OR the high (.HAI) and low (.LAI) alarm limits of the AIN and connect to the HOLD in the ACCUM block. The ACCUM should only accumulate when not high or not low. Brian -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx]On Behalf Of Jaime Claramunt R.
