Different board will have different channel of digital output, digital input , ADC, DAC, so the protocol is same , just according to the hardware resource to set channel number.

“KCS” means “KinCony Super” , this is a new firmware developed by KinCony for KC868-A series products in 2023. It has powerful functions and supports multiple communication protocols. It can manage various functions of the device through web pages, such as: input configuration, output configuration, monitoring management page, Timing schedule task mode, network configuration, communication protocol configuration, system configuration and other related functions


Input configuration:


Binding of digital input port and output port, setting of effective value of high and low level, support multiple trigger modes through digital input port, such as: single click, double click, hold on mode

Output configuration:


Output level invert, support delay auto off, support jog mode control, support interlock setting

monitoring management page:


Monitor the status of the input in real time through the web page, and manually control the output

Timing schedule task mode:


Support custom scheduled tasks by year, month, day, hour, minute

Network Configuration:


configuration of ethernet and wifi

Communication protocol configuration:


Support MQTT, HTTP, TCP Server, TCP Client, UDP Server, UDP Client, Modbus multiple communication protocols

Tuya App configuration:


Configure Tuya app license to remote control board by internet

System Configuration:


default parameter settings

Hi All,

I just purchased one board KC868-A8S but is seems i am usung wrong protocol.

When sending any message i receive an just an echo of same command.

i need to flash any firmware?  
where i can find a communication protocol?

Please help, 
Luigi.

How to make communication with an HMI, by Ethernet?

command does not work, it was supposed to give a command that if button 1 was LOW, it would activate output P0, what did i do wrong to make it not work?
