Hello!
I am fairly new to RapidSCADA (it is my first project).
I have managed to configure an interface that communicates with an Arduino, via Modbus TCP and read all the sensors data from it (I primarily read floats from Arduino and managed to do that by byte swapping, when defining the input channels in the Device Template Editor).
Now, I want to send data to the Arduino (setpoints for each measurement) so that the Arduino knows what to do with each measurement. Problem is I can’t figure out where and what to write in order to write the holding registers to Arduino, via Modbus TCP.
Could you please help me?
Thank you in advance!
