PLC installed in home

At my home I have a small PLC installed to monitor various temperatures (and eventually weather varaibles and security sensors). It's a "just for fun" project.

its like a shooting to a fly with avenger cannon :D plc is very expensive and simple microcontroller would do this and much more with smaller room and less power consumption :D

@qubolo I agree that a PLC is more expensive than a microcontroller for the same functionality, but the biggest purpose of me doing this was to become more familiar with programming HMI panels to interface with PLCs. In other words, it was more of a learning project than a practical project.

I would do it for fun. says the student. I would like to know of any cheep PLC´s with LAN so i can control the plc with a panil computer for home automation. Its a school project.

@Mr4yOK I'm planning to upgrade from the old DirectLogic 06 PLC to a new CLICK PLC with RS-485 Modbus capability. The CLICK model of PLC is about as cheap as it gets for a multi-drop network-able PLC. Very easy to set up and use, plus it even has two build-in analog input two more analog output channels!

This is cool. Are you married? My wife would never let me play with this kind of thing in our house. I barely get away with X-10 stuff. :)

We'll celebrate our 13th year of marriage this October. She is very understanding . . .

@BTCInstrumentation use ardiuno with ethernet shield cost less than 100 bucks lol

Very nice, one use for this is with hydronic heating, known as "outdoor reset", where it can compare the temperatures to adjust its rate of heat delivery. Cold hours it will ramp up, and warmer hours it will ease off.

Use your big boy voice!!! In a closet, we should be able to hear you.

Muito mau montado este painel, porque toda a fiação está esposta, não tem canaletas semi-abertas, nem anilhas de identificação dos condutgores. Pelo visto também, falta o condutor de aterramento.

@qubolo yeah... but after working with both I have to agree that PLCs are so much easier to work with. also... seeing the prices for old/used PLCs I'd probably look into them if I were you. they aren't as unaffordable anymore.

nerds what can you do

A friend of mine has his PLC controlling his natural gas furnace.. and also the cooling fans.. plus has temp sensors in each room which will cool or heat the preset temp in each room. I would like to do the same with my PLC.

I heard that a PLC could monitor gas flow in/out, burner temps, gas controls, thermocouples, etc. The electro-mechanical controls on my gas furnace are ancient (1980's era) and could be updated.
