Timer with pulse outputs?

[gparinger]

Hi all,

I'm quite new to PLC programming and have a problem to solve.

I my house I have a easy800 with springloaded input switches(pulse use).
After the easy 800 I have some din mounted dimmers (pulse operated on/off, hold for dimming)
and also some more standard relays.

For operating the dimmers I have used normal contactors when programming, and for the other relays I've used impulse relays.

Now to the question:

How do I manage to:

- Get 1 pulse when a 7daytime-switch turns on?
- Get another pulse when the time switch turns off?

Appreciating all help!

No one?

I am also having trouble finding out how to solve a master/central on/off function.

Very grateful of all help I can get...

Dear gparinger.

Attached please find a small example how to get the pulses.

In case a pulse with the length of 1 cycle is sufficient you may use marker directly. If a longer
time is required you have to use timers.

Thank you Maikky!

I'll test that!

Those pulses worked fine!

Still i have problem solving my master on/off. With set/reset i belive it would be working unless i had those dimmers functioning with pulses.

Illustration:

input - > Easy module --pulse to--> dimmer -> lightbulb

The problem for me to understand is how the "master off" switch "knows" which dimmers allready is on?

Dear Gustav.

You can use the status of the outputs to select whether the lamps are on or off.

Attached please find an example.
