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
