    • RE: Arduino Mega - analog inputs

      Hello Martin,

      I have noted that the Arduino analog inputs can sometimes pick up signals from adjacent channels.
      You can try pulling the analog signals to ground with a 10K - 100K resistor to see if it corrects the unwanted readings.

      Cheers,
      Tom

    • RE: Raspberry Pi and Click PLC, Modbus TCP

      Hello folks,

      I just wanted to confirm that reducing the "Max. requests" number to 1 allows multiple Modbus reads of the Click PLC.
      I agree that reading registers in groups of 4 or 8 is more elegant and will try that next.

      Cheers,

      Thanks, Jarslav

      I knew it had to be a timing issue! Just not familiar enough with the system yet to know what to adjust. Will keep the forum updated.
