Hi, i understand in this way: I use to search wath alarm condition has been triggered. I have about 300 alarms conditions, in the source i create an array (same size of alarm number, in my case is almosto all 0's). The reference array contain my system alarms (Always 0, and 1 when triggered). I use the search mode "One mismatch a time"; then i put to work cyclical. When one alarm is triggered, the position of Result Control, shows in what bit was found the diference o mismatch. I use this number to display a alarm message on a PView. Then i unlatch the .FD bit, to continue searching any mismatch between the source and reference. I hope it help you. Isaias Frias Rguez
