Modbus help

Hello, I’m trying to learn Modbus. I downloaded the ‘master with 8 buttons, slave with 8 LEDs’ example from the Flowcode examples via the website and understood the logic behind it.
However, I couldn’t manage to turn on a single LED on the slave using just one button on the master.
Also, I want to use the master node with two buttons (up and down) to control PWM on the slave node.
I kindly ask for your assistance.

Can you let me know what hardware you have and the link to the demo you downloaded?
