Ron, I think what is missing is to be able to ACK alarms when you are not in = front of a workstation. Perhaps there is only one operator who is in the = field working when an alarm comes in. It would be nice to cut off the = klaxon before he has to go all the way to the screen. Perhaps he was = doing something that he knew was going to fire the klaxon, so he already = knows what caused the alarm. Not an easy solution in IA where the alarm system is based on the = premise that you need to see what caused the alarm (be in front of a = workstation) in order to ACK it. This is not necessarily a bad idea. He could probably take a contact input to an IND block where the IND = will force a display manager command in a station where the alarm is = active and that station is in a common alarm group with the other = stations receiving the alarm. Terry Object=A0: Re: [foxboro] Silence Horn functionality without Annunciator = Keyboard Did you know F12 on the regular keyboard will also do it? Maybe you can turn on the On-Screen Keyboard and use the F12 there? That is if you have a workstation. Also, I would think that you could use a discrete input (button) and have it trigger in a seq block to do a silence horn silence command. Anyone else have ideas? Ronald G.
