MPINO STUDIO 2 Phase 1 · Create Your First Project

This document is for first-time MPINO Studio 2 users. You will create a ladder circuit in which output P32 turns ON while input P0 is ON, then build, upload, and monitor the project.

About the screenshots: The screenshots show the Korean interface. Button positions and keyboard shortcuts are the same as described below.

Prepare the following items.

• A PC with MPINO Studio 2 installed
• An MPINO-8A4R(T)-S board
• An MP download cable (for MPINO-8A4R(T)-S)
• A P0 input signal wired according to the product manual if you will perform the live input test

For the first test, complete programming and uploading with the output load disconnected.

MPINO Studio 2 opens ① an Untitled project that you can edit immediately. The Explorer already contains ② the main code tab and ③ the ladderLoop ladder tab.

On the first launch, a notice about automatic error reporting appears once. Read the notice and select OK to close it. You can later change this option under File → Preferences → General → Send error reports automatically.

Identify these areas before editing the project.

1. ① Menu bar: File, Edit, View, Run, Settings, and Help
2. ② Activity bar: Explorer, Ladder Settings, Ladder Pin Map Settings, Library, Symbols, Serial Monitor, and Settings
3. ③ Sidebar: Project and board information for the selected activity
4. ④ Editor: Arduino C code or ladder circuit editor
5. ⑤ Bottom panel: Build output, problems, mnemonic view, and Serial Monitor
6. ⑥ Status bar: Current status and port selector

⑦ Ready at the lower left is a static label. Use ⑧ Select Port at the lower right to choose the serial port for uploading.

1. Select File → New, or press Ctrl+N.
2. If the current project contains unsaved changes, choose whether to continue in the confirmation window.
3. In the board selection window, select ① the MPINO-8A4R(T)-S card.
4. Choose ② Select, press Enter on the card, or double-click it. Press Esc to cancel.
5. When the new project opens, press Ctrl+S to choose its name and save location.
6. Open Settings → Ladder Pin Map Settings, select Use for the P0 and P32 rows, and select OK.
7. Press Ctrl+S to save the pin map settings in the project.

Selecting the board does not create a file on disk. The name and location of the .mp2 project file are set when you save it.

In the Explorer, select ① Ladder → ladderLoop. Select a grid cell first, then use a toolbar button or function key to place an element in that cell.

1. Select row 1, column 1, then choose ② NO contact or press F2.
2. Select row 1, column 2, then choose ③ output coil or press F9.
3. Press Enter on ④ the first cell or double-click it, then enter P0 as the address.
4. Press Enter on ⑤ the second cell or double-click it, then enter P32 as the address.
5. Confirm that your screen matches the figure below.

Press Enter on ① the selected cell, or double-click it, to open the edit window. Enter the value in ② the address field, then choose ③ OK. Contacts and coils use the same style of input window, so check the selected cell and address before confirming.

This tutorial uses only F2 and F9. The completed circuit turns P32 ON while P0 is ON.

During a build, MPINO Studio 2 converts the ladder data in the .mp2 project into C code and compiles it with the Arduino toolchain. The ladderLoop tab becomes the ladderLoop() function.

void setup() {
}
 
void loop() {
  ladderLoop();
}

When ladderLoop() runs, the ladder logic you created runs. Therefore, it must be called from loop().

1. Select Run → Build, or press Ctrl+R.
2. Confirm that the bottom panel switches to ① Build Output.
3. Wait for the compilation log to finish.
4. The build succeeded if the final line contains ② [arduino-cli exit 0].

If the build fails, start with the error summary and the last part of the log. Check the selected board, cell addresses, and code syntax in that order.

Caution: Uploading does not start until a port is selected.

1. Connect the MPINO-8A4R(T)-S board to the PC with the MP download cable.
2. In Windows Device Manager → Ports (COM & LPT), check for USB Serial Port (COMx). If it does not appear, install the FTDI driver for the MP download cable and reconnect the cable.
3. Select ① Select Port at the right side of the status bar.
4. Choose the required port, such as COM3, from ② the open port list.
5. Select Run → Upload, or press Ctrl+U.
6. Confirm that the upload log continues below the build log and ends normally.

The port list refreshes automatically when the drop-down opens. You can cancel an upload from the bottom panel while it is running.

Select ① Serial Monitor in the Activity bar. Choose ② the baud rate and ③ character encoding, then select ④ Connect. Use ⑤ the ASCII/HEX control to change the display mode, and check ⑥ the connection state at the right.

Before using real-time monitoring, select a communication port under File → Preferences → Ladder Settings → Monitoring Port, then build and upload again. After that, press Ctrl+M or select ① Monitoring ON in the ladder view.

When a physical input signal reaches P0, ② the P0 contact and ③ the P32 coil are highlighted. Press Esc to stop monitoring.

You have completed Phase 1 when all of the following are true.

• You saved the .mp2 project.
• MPINO-8A4R(T)-S is selected as the board.
• The first row of ladderLoop contains the P0 contact and P32 coil.
• The build log ends with arduino-cli exit 0.
• You selected the correct port and uploaded the project.
• The P32 coil's monitoring state changes with the P0 input.

For MPAINO-8A8R(T), the first input is P0 and the first output is P64. Use the editing, build, upload, and monitoring controls described above, with the board, output address, and PC connection shown below.

Connect the USB download port on the MPAINO-8A8R(T) CPU module to the PC with a standard USB cable. In Windows Device Manager → Ports (COM & LPT), check for Silicon Labs CP210x USB to UART Bridge (COMx). If it does not appear, install the CP210x driver for models with a built-in bridge and reconnect the cable.

1. Select the MPAINO-8A8R(T) board under File → New, then save the project.
2. Under Settings → Ladder Pin Map Settings, check that Use is enabled for input P0 and output P64, then save. Confirm that the relay (R) or transistor (T) output type matches the delivered product.
3. Place an NO contact at P0 and an output coil at P64 on the first row of ladderLoop. Figure 5 shows the MPINO example; enter P64 instead of its P32 coil address.
4. Follow Build → Select the COM port above in the status bar → Upload → Verify Operation. Check wiring against the MPAINO-8A8R details or the specification for your T model.

Other MPAINO models can have different I/O counts and module configurations. Check the pin map of the selected project board and use the addresses for your model.
