KN PLC Programming Tool

This is a ladder logic editor developed using QT Widgets. User can create Ladder Logic networks and upload it to KN PLC. KN PLC is a programmable logic controller with core functionality. It is built around Arduino Mega 2560.

It supports:

• 8 x Digital Inputs
• 8 x Digital Outputs
• 8 x AUX
• 2 x Counter
• 2 x Timer

Dependencies/Pre-requisites

• platformio (CORE) >= 4.x not required to build but in order to run

  • To install platformio, see https://docs.platformio.org/en/latest/core/installation.html

• Qt >= 5.12.1

  • To install Qt, see https://doc.qt.io/qt-5/gettingstarted.html

Build instructions

1. Clone this repo.
2. Run the commandin top level directory: qmake -makefile
3. Build it: mingw32-make

Usage

After succesfully compiled, execute the command:

./release/kneditor.exe

NOTE: if platformio is not in the PATH you cannot upload the program to Arduino.
