M-Duino 58: Arduino PLC with 58 I/O and Ethernet

The M-Duino 58 is an industrial PLC from Industrial Shields built around an original Arduino Mega 2560. It has 36 inputs (16 analog 0-10 V) and 22 outputs (8 analog/PWM), Ethernet, RS-485, RS-232, I2C, SPI, a real-time clock and a microSD slot, and mounts on a DIN rail. It is programmed with the Arduino IDE, with no licence fees, and suits large or distributed installations that need high digital and analog I/O capacity.

Before you choose the M-Duino 58

How do I program the M-Duino 58?

With the Arduino IDE (1.8.0 or later). Install the Industrial Shields boards package from the Boards Manager and select the M-Duino 58. Upload through USB; the Ethernet port also lets you maintain it remotely.

Does it have relay outputs?

No. Its outputs are optoisolated digital and analog/PWM outputs. If you need relays, look at the M-Duino models with relay outputs, such as the 19R, 38R or 57R.

Can it talk Modbus?

Yes. Use Modbus RTU over RS-485 and Modbus TCP over Ethernet with the Industrial Shields Arduino libraries. It can act as master or slave.

Can the analog inputs read 4-20 mA sensors?

The analog inputs measure 0-10 V with 10-bit resolution. To read a 4-20 mA loop, add a precision shunt resistor (500 Ω turns 20 mA into 10 V) and scale the reading in your program.

Does it keep the time and log data?

Yes. It has a real-time clock and a microSD slot, so it can timestamp events and log data locally.
