Modular PLC
This is the first equipment based on the Arduino technology designed for a professional use. This PLC has 34I/Os1. It also contains several communication systemswhich 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.

Instantantaneous 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.

Solar panels are popular because they are able to give us energy from light. When the light hits the panel solar conductor, the energy is translated into moving and electrons, creating current. In this newsletter we´ll make a simple monitoring

    Comunicación via ethernet con un sistema de control de producción. Encajado y paletizado en semi-automático y envío por lotes a entrada de almacén caótico. Funcionamiento sin problemas destacables, la programación quizás lo más entretenido hasta conocer el entorno, diferente de otros controladores que tenemos en planta.

    Great performance. This Arduino controller rocks!
    Guys, you should integrate prog soft in your own plc. I’m just sayin’

    Hemos usado el PLC como parte intermedia de comunicación en una máquina de limpieza y descarte de botellas. El lavado es por aspersion a un tope de 12.000/h. Se ha integrado con un equipo de visión y las cintas de rechazo y ok. Funciona sin ningún problema.
