Field wiring, COM grouping, and the full Arduino pin map for the MPAINO-32A16R are documented in the user manual (download below). Digital inputs are opto-isolated and accept NPN or PNP sensors depending on COM wiring; outputs and analog ranges follow the terminal layout in the manual.
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.
This board can also be used without the ARDUINO SDK by selecting the MEGA2560 board in the Arduino IDE. In that case the ILOGICS built-in commands are not available. The expanded outputs (D70~D85) still need the ARDUINO SDK to be driven.
