audible alarm silence rung

[campos26]

Currently I have a simple rung of logic written from an input to a B3 bit for a run status on a pump. When the pump goes down, or the input becomes false, the audible alarm goes off. I need to tie in the status bit into the horn silence sequence. Attached is the snapshot of the rung included when I opened the program. Thank you in advance.

Connect a PB to a TON. Seal the PB with the TON's TT bit. Use the TON's TT bit to interrupt the logic to the output on rung 29. When the timer expires (PRE = ACC) the noise will return.
