Bonjour
J'ai plusieurs contrôleurs mais ils ne peuvent pas interagir entre eux en par le contrôleur logique
un conseil;merci .

Dears I bought PLC Kincony with extension keyboard and 32 channel expansion. My problem is connect switches from rooms to PLC.

I show my cabinet

Cabinet
Wall cable

and I prepare drawings - how I connect.

But not working correctly. For example I short 2 wires from 1st room - connected to K1 i K1com  couldn't turn on/off  1st relay,and after connect wires to extension ports the Keyboard not switches correctly relays too.

How it should be connected? 

Did I need a special wall switches for that ?


I bought my parts on january 2020 , now I see the different module . i'm afraid to buy now because I'm not sure that I connect existing board.



Please help for me. Thank You.

update: when power on of KC868-COL, autoreport analog and temperature value at least one time.

Hello...

At first I was about to purchase the 32-channel, but then after some digging.. I need some advise to clear things up.

I'm new at this and I am building an automation system that is to be control with home kit and I am ready to try the KC868. I gonna control about 24 nos of circuit using an AC contactor. The requirement is that I need a manual switch (start/stop) for the contactor that can interrupt the circuit anytime it need to be. I first thought H32B should do the job, but when required to make a manual override switch, I need 2 relays for 1 circuit to make it possible (I couldn't figure out any other design other than this solution). But also I found that I need access the NC port on one of the relay - thus the choice is KC868-H16B, and it seems it requires 3 of them to control all the 24 circuits.

My question is :
1. I couldn't find much info, but I read we can use multiple KC868 at the same time. So, how does it works? Do they communicate with each other via the RS232 port and will they all be using single IP or will the KC868 IP be independent from each other?
 
2. If they uses different IP, can the home assistant server control 3 KC868 at the same time? Or I need to setup 3 servers?
 
3. I also need at least 24 DI inputs (3 x 8 input on H16B should be enough) so that I can know the status on the main circuit if it's on or off, not the status of the onboard relay because it will actually tell me the status of the control circuit, physically. Do you think it should be sufficient?

Attach are my setup on trying to make this work.. :-) I need to show this PoC works first before I an ready to deploy.

Thanks in advance.

Dear Admin.

I have purchased this Humidity and Temperature Sensor with 4 wires (Red, Black, Yellow and White). 
I am using the COL and i need to know where do i have to connect these 4 wires to?

Now writing the program code
       

Hi,

I have installed COL + H32L module to automate home.
however i have problems programming COL, as i cannot get the output on relay 30 when digital input 2 is active.


I see input 2 active, but out 30 never works.

Dear Admin.

How do I change the color (Green, Amber and Red) on the measuring bar as a picture? 
For example, if the temperature is between 30C to 35C it's green and when the temperature is between 36C to 40C is Amber and 41C onwards is Red.

I can't find what the code is and where to place it. 
Could you please show some examples?

Thank you
Subas

KC868-COL support use analog sensor that 0-5V output, if you already have 4-20mA sensor. you can use a 250 Ohm resistance connect with signal input port and GND to convert.

To convert a mA analog input signal to voltage you need to attach a inline resistor. The size of your resistor will determine the output range of your voltage. 

Resistor Calculations are as follows:

Using ohms law V = R(I)  (Voltage = Resistance * Current)


If we were to scale a 4-20mA to 1-5V

For the 0 Value: .004 Amps * 250 ohms = 1 Volt

For the Max Value: .20 Amps * 250 ohms = 5 Volts
