Arduino PLC based details

Industrial Automation

Modular PLC
This is the first equipment based on the Arduino technology designed for a professional use. This PLC has 21I/Os. It also contains several communication ports which provide more flexibility and control. The M-DUINO family offers the possibility to expand up to 127 modules through I2C, which means that you can have until 7100 Inputs / Outputs in Master-Slave connections, additionally to sensors, etc…

Programming Software
This PLC can be programmed using the Arduino IDE platform. See the Documentation menu below to download the software for free.

Instantaneous connection and coding
The PLC M-DUINO is programmed through the USB ports. This PLC can also be programed through Ethernet port remotely. This offers and immediate access to program, mantain and control. Also you can continuously monitor the status for all the variables, inputs, outputs, etc. It is compatible with the Arbosx and the Touchberry Pi with instantaneous connection.
