Additional information

PLC Arduino details

Controller Arduino for Industrial Automation: monitoring, process control and Data Acquisition

Modular PLC controller
This is the first equipment based on the Arduino technology designed for a professional use. This Programmable logic controller has 58I/Os. It also contains several communication ports which provide more flexibility and control. The industrial controller 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 with Open Source
This Industrial 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 Arduino PLC M-DUINO is programmed through the USB ports. This industrial Arduino PLC can also be programed through Ethernet port remotely. This offers an 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 Ardbox PLC Range and the Touchberry Pi with instantaneous connection.
