Communication I/O Control
When field devices must talk to a master controller, SCADA, or HMI, ILOGICS communication I/O controllers provide hardware serial channels — RS-485 with automatic direction control, RS-232, and TTL UART — plus an industry-standard Modbus RTU stack. ATmega2560-based models expose up to three independent serial ports simultaneously, letting one board bridge sensors, drives, and supervisory systems on the same network.

Frequently asked questions
Are MPINO controllers programmed in the standard Arduino IDE?▾
Yes. MPINO boards use the MegaCore Arduino core and are programmed in the standard Arduino IDE. Select the ILOGICS board entry, the AVR ISP programmer, and upload with the dedicated MP download cable.
Can these controllers replace a traditional PLC?▾
For many machine-control and data-acquisition tasks, yes. MPINO controllers provide opto-isolated field I/O, relay or transistor outputs rated for real loads, and Modbus RTU networking — with the flexibility of the open Arduino ecosystem. For safety-critical systems, always add an independent safety circuit.
What communication interfaces are available?▾
Depending on the model: RS-485 (with automatic direction control), RS-232, TTL UART, and I²C. ATmega2560-based models can expose RS-232, RS-485 and UART simultaneously. Modbus RTU master/slave is supported via the ILOGICS ILIB library.
