Title: Turn off an output
Post by: bl on February 03, 2009, 07:24:36 PM

I was trying to find out where the option to turn off an output is but I couldn't find anything.I need an input to turn off given output.
Some help where exactly it is will be more than welcome. I am using Trilofi 6.22.
One thing that I noticed since using Trilogi-it is not very intuitive.

If you use a NO contact (INPUT) in serie with the coil (OUTPUT). The ouptup will be on as long as the input is on.
Another way to control is using a dcus and use the TOGGLEIO function.
Check the Programming Manual.

It will not work because any time when the input is OFF the output will be ON.
E.g. Power button-when it is OFF the given output/s will be ON.

You have to use a normal open contact from input. The way as you said, looks like you are using a normal close contact.

Use the [Latch] and [Clear] functions.
