Wiring & pin map
Field wiring, COM grouping, and the full Arduino pin map for the MPINO-16A8R8T 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.
Communication
The MPINO-16A8R8T exposes RS-485, RS-232, UART, I²C interface(s). Modbus RTU master/slave is supported via the ILOGICS ILIB library, so the controller can sit on an existing fieldbus or act as a gateway to an HMI or SCADA system. I²C is available for local displays, RTC modules, and operator panels.
Software & examples
Program the MPINO-16A8R8T in the standard Arduino IDE using the MegaCore core. Select the ILOGICS board entry and AVR ISP programmer, then upload with the dedicated MP download cable. The ILOGICS ILIB library provides Modbus RTU and industrial helpers; standard Wire and EEPROM libraries are supported. Refer to the user manual for analog reference setup (analogReference(EXTERNAL)) and timer/interrupt resource notes.
