Arduino OPTAはIEC61311-3規格に準拠したラダープログラムで動きます。このラダープログラムはArduino PLC IDEでの制作します。 OPTAはラダープログラムだけでなく、よく知られているArduino IDEで作成したC言語でも動きます。 これまでRaspberryPIとCODESYSの組合せで、制御 ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...

The following tutorial will explain how to transform the potential of popular microcontrollers into programmable logic controllers (PLCs). This primer is for those who want to begin learning about ...
