Arduino PLC based details
Modular PLC Arduino
This is the first equipment based on Arduino technology and designed for a professional use. This industrial PLC has 57I/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…
This controller arduino can be programmed using the Arduino IDE platform. See the Documentation menu below to download the software for free. A ladder logic option will be available soon.
Instantaneous connection and coding
The industrial arduino M-DUINO is programmed through the USB ports. This open source based PLC can also be programmed through Ethernet port remotely. This offers an immediate access to the program, maintaining 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 an instantaneous connection.
