Title: switching roller shutter motor with one push button
Post by: rozik on December 28, 2018, 09:17:13 AM

Hi

Is it possible to control a roller shutter motor with only one push button in ladder or with custom function.

The switching must go as following   up/stop/down/stop/up/stop/down......

Is there someone who could helpe me further, ore have any suggestions.


Thanks in advance
rozik

Rozik,

I would implement a simple "drum sequencer" in ladder logic.

I have attached a pdf of how you could write a sequencer for the problem that you stated.  

You should be able to copy this example and run it under the iTRILOGi simulator.

Best regards,
