Modbus Tcp For PIC24FJ64GA104 Microcontroller


Recommended Posts


Have successfully used DF and Modbus RTU. Setup was a PC or laptop running Windows 7, internal Wi-Fi adapter, Roving Networks Wi-Fi radio module on my PCBA. Controling my LED light fixtures (dimming, on and off) using my prorpietary hardware and firmware.

I am writing all of the Modbus TCP slave code (PIC24FJ64GA104 controller).

Want to move to Modbus TCP with DF - any advantage to this?

Reason for change is to work with other companies that have Modbus TCP devices (slave and/or master).

Within DAQFactory, it doesn't care if you do Modbus TCP or Modbus RTU, so you should decide which one you want irrespective of DAQFactory.  DAQFactory can do both, and either on both serial and Ethernet.  

That said, ModbusTCP slave is a tad easier to implement because you don't have to worry about a CRC.
