Follow these steps to upload a program to an MPINO or MPAINO product and check one digital output and input. Input 0 and output 64 in the examples are for MPAINO-8A8R(T). For another product, replace them with the addresses in its pin map.

Read the full model name, R/T output type, and power-input specification on the product label. The output type determines how you connect a load and check its operation.

• MPAINO-8A8R(T): The examples use input 0 and output 64. Check the terminals and addresses in the 8A8R or 8A8T pin map.
• Other MPAINO and MPINO models: Open your model under MPAINO Series or MPINO Series and check the input and output addresses you will use.

1. Check the terminal names and power polarity against the product manual.
2. Check COM wiring and the upload cable specified for the product. For the MPAINO-8A8R(T) in this example, connect a standard USB cable to the CPU module's download port.
3. Leave output loads disconnected for the first upload and output check.
4. Provide emergency-stop and overcurrent-protection circuits independently of the program.

1. Download and install the Windows Arduino IDE installer from the official Arduino download page.
2. Download and run ARDUINO SDK INSTALL from the ILOGICS Arduino SDK download page. It adds the ILOGICS board definitions to Arduino IDE.
3. Close Arduino IDE and start it again.
4. Connect the product to the PC, then select its board and port as shown below.

Click the board selector at the top of Arduino IDE and choose Select other board and port…. This actual Arduino IDE screen shows MPAINO-8A8R(T) in the search results.

After connecting the MPAINO-8A8R(T), Windows Device Manager → Ports (COM & LPT) showed Silicon Labs CP210x USB to UART Bridge(COM1). Arduino IDE showed the same port as COM1 Serial Port (USB). Match the COM number when selecting the port.

Arduino IDE may show COMx Serial Port (USB) rather than the driver name. Products that use an MP download cable appear in Windows Device Manager as USB Serial Port(COMx). Distinguish that port from the CP210x port used by this MPAINO example.

If no COM port appears in Device Manager, install the driver for your connection and reconnect the cable.

• Products with built-in CP210x, including MPAINO-8A8R(T): CP210x USB driver
• Products using an MP download cable: FTDI USB driver

If the board is already selected, you can choose the same port from the menu: ① Tools → ② Port → ③ COM1.

Selecting only a board is enough to verify code, but uploading also requires a port.

The sketch below turns MPAINO-8A8R(T) output 64 on and off every 0.5 seconds.

const uint8_t OUTPUT_CHANNEL = 64; // MPAINO-8A8R(T) example
 
void setup() {}
 
void loop() {
  digitalWrite(OUTPUT_CHANNEL, HIGH);
  delay(500);
  digitalWrite(OUTPUT_CHANNEL, LOW);
  delay(500);
}

For MPAINO-8A8R(T), the ILOGICS SDK's main() configures the output pin before setup() runs. This example does not need a separate pinMode() call.

1. Open File → New Sketch and enter the code. For MPINO or another MPAINO model, change OUTPUT_CHANNEL to the first output address in that model's pin map.
2. Save the sketch with Ctrl + S.
3. Click Verify (✓). Compilation is complete when the output panel shows no errors and Done compiling. appears.
4. Check the board and port, click Upload (→), and wait for the completion message.
5. With the output load still disconnected, check that the indicator for that output changes state every 0.5 seconds, if fitted.

You may also hear a relay contact switch. Without an external supply and load, a transistor output cannot be measured like a voltage output. If the product has no output indicator, first check the output test method in its manual.

This example reads MPAINO-8A8R(T) input 0 and applies the same state to output 64. The output turns on when the input is HIGH and turns off when it is LOW.

const uint8_t INPUT_CHANNEL = 0;   // MPAINO-8A8R(T) input example
const uint8_t OUTPUT_CHANNEL = 64; // MPAINO-8A8R(T) output example
 
void setup() {}
 
void loop() {
  bool inputState = digitalRead(INPUT_CHANNEL);
  digitalWrite(OUTPUT_CHANNEL, inputState);
}

Verify (✓) and Upload (→) the sketch. Connect the input signal as shown in the MPAINO-8A8R(T) manual. Change its state and check that the output state changes with it. MPAINO digital inputs have built-in pull-down resistors. For another model, use addresses from that product's pin map and check its input circuit.
