Hello -
I'm looking to force the BCS Alarm to Reg10 so I can simultaneously assert a physical alarm/buzzer as well. I've read through http://wiki.embeddedcc.com/index.php/La ... egister_10 and the only question I have is on the DIN0 (Input button) contact. My Input btn is a NO momentary push button. i.e. when pushed, it sends a signal to the BCS. In the second rung (to cancel the alarm), the DIN0 contact is NC. Is that because of the ladder logic (the contact needs to be 'closed' to keep the Reg10 coil until the 'wire' is interrupted?) Nothing to do with my NO button and how physically DIN0 gets a signal?

Re: Ladder Logic to Alarm/Output
I am not sure of the logic but it does work.
I have Din0 wired to a momentary push button. I have Out5 as an SSR to my 120vac Alarm Circuit.
Pushing the Button (Din0) or clicking the Alarm Off on the Web Interface cause the alarm to turn off.

Re: Ladder Logic to Alarm/Output
When I went back, my Alarm Off switch did not work. Here is the correct diagram. When I was making the graphic, I selected Reg 0 and not Reg 10. Duh!
