Can Maple Systems HMIs communicate with Arduino Opta? I would like to use AFX00001, AFX00002, or AFX00003 if possible?
Yes, the the AFX00001, AFX00002, AFX00003 modules support Modbus TCP (Ethernet) and Modbus RTU (RS485 serial) protocols.
All of our HMI/CMT and HMI+PLC combo units support communications to these modules.
