Software
Arduino IDE / MPINO Studio 2
Arduino IDE compatible
Works with the Arduino toolchain you already use
MPINO STUDIO2 included
Arduino code and ladder logic in one tool
Arduino + ladder logic
Build control logic faster with familiar ladder rungs
Setting up the toolchain
Using the Arduino IDE requires the ARDUINO SDK (the ILOGICS board package) to be installed. It is not required when you work in MPINO STUDIO2.
