Modular PLC
This is the first equipment based on the Arduino technology designed for a professional use. This PLC has 42I/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.

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

    El mduino está como parte de un sistema automático de gestión de producto semi-acabado. Por peso y según cinta de transporte de llegada se distribuyen los lotes al siguiente estadio donde se pasa a la fase de acabado.
    El producto tardo en llegar algo más de una semana y la integración costó más de lo que teniamos previsto. Por el momento el plc funciona correctamente.

      Sr. Priego, sentimos la demora en la entrega. En cuanto a la integración no dude en solicitarnos soporte, estamos aquí para ayudarles en todo lo posible.
