In the videos below I show using Flowcode App Developer to create a Modbus TCP controller.
I use an Arduino Uno as my Modbus TCP Slave device and connect a LED to the Arduino.
Then using a simple switch in App Developer I show how to turn the LED on and off on the Arduino.
Included is how to setup the App Developer project and how to export as a project you can distribute.
Next I show how to take the application further by adding more features including.
- PWM Output
- Analog Input
- Digital Input
