Hello all.
I’m currently working in an indoor project to monitor two water tank level at residence;
I’ve tried to developed a solution using two arduinos UNO with Ithernet Shield attached into each board (as slave);
Also, i built a Winccc Run time application (as master)to monitor those water levels from my laboratory;
The sensors used ar HC-SR04 Ultrasonic and they are fine and i can read its values at serial monitor as should be.
I have installed MgsModbus - v0.1.1 and ethernet libraries to run at this topology.
After all setting i’m facing a issue and i cant read values from both Arduinos ate same time, i can just read from one board;
I addressed each board with proper IP and are as follow final 0.10 and 0.20;
Any of you guys can help me on this matter?
Many thanks for your support.
