Q: Do I have to purchase a license to program ladder logic with my Opta PLC?

A: The Arduino Opta PLC has a license to use the Arduino PLC IDE. This will allow you to program in the standard 5 programming languages and C++ (Sketch).

Q: How are the discrete inputs wired for the Opta PLC?

A: The Opta IoT PLC datasheet specifies that the supply voltage should be 12 to 24VDC. The inputs will turn on when the voltage reaches 6.6 VDC and off when it drops to 4.46 VDC. The Opta’s discrete inputs (on/off) will switch to +DC voltage. Since the controller input common is at 0 VDC, this is considered a sinking input. You can refer to a post that covers the wiring of NPN and PNP 3-wire sensors for more information. 3-wire sensors should have PNP outputs. The Opta PLC input will replace the load shown in the sensor wiring diagram.

Q: How does the regular Arduino IDE software upload code to the Opta?

A: Using the regular Arduino IDE software, you must activate bootloader mode to upload code to the Opta. Connect your Arduino Opta IoT PLC to your computer via a USB ‘C’ cable that can handle both power and data. Simply double-tap the reset button on the Arduino OPTA PLC to activate bootloader mode, indicated by the CPU’s pulsing light. You can now proceed to download your program code.
