hello,
I am thinking on the possibility of using an Arduino to receive 7 analog signals (4-20mA), and after some manipulation, for example one of the signal is from a temp sensor (4-20mA == 0-40C), output these signals in a MODBUS format, TCP/IP ideally but RTU RS485 in the worse case scenario.
Also, at the same time some data will be received with the same protocol (MODBUS), to actuate valves through AOs or relays.
Is this feasible with Arduino?
