Interfacing advancedHMI to arduino
« on: March 03, 2020, 03:35:36 PM »
Am using digitalpanelmeter to read temperature from arduino. In serial monitor, am getting 27 degrees and getting strange readings on the panel meter, 6298 degrees. What could be the cause?

Am using Ethernet. I have set my PLC address to 40001. I have included modbus.h library in the arduino code

Have you tried changing the swap byte and swap word properties?

Thanks Archie,

Swapping bytes did the trick. Now able to read the same value seen in serial monitor.
