I often come across situations where communication between computers and PLCs doesn't work as expected. Most of the time, it's not because the PLC isn't powered, but rather due to incorrect port settings on the communication line. There are several common programming cables, such as SC-09, USB-SC-09, and USB (printer) cables. When using an SC-09 cable, if your computer lacks an RS232 port, you'll need a USB-to-RS232 converter. When purchasing this converter, make sure to mention that it's intended for Mitsubishi PLC programming—some people buy it for MCU projects, which can lead to compatibility issues. After connecting, you’ll need to install the driver. Once installed, the converter will appear as a virtual RS232 port in the device manager, like COM4. Make sure to select the correct port when downloading or uploading programs during the process. For USB-SC-09 cables, the same applies: install the driver, check the device manager for the virtual COM port, and use that during programming. If you're working with a Q-series Mitsubishi PLC and using a USB cable, the first connection might prompt your computer to detect new hardware. In that case, the driver should be located in the installation folder: MELSEC\Easysocket\USBDrivers.
