The USB8550 USB-8550 cable USB to RS422 all adapter for Nais/Panasonic FP1/FP3/FP5 PLC. The Panasonic USB-8550 cable is used for programming and communication with Panasonic FP1, FP3, and FP5 series PLCs. This cable allows you to connect a PC or programming device to the PLC for tasks such as program uploading, downloading, monitoring, and troubleshooting.
Components Needed:
- Panasonic USB-8550 Programming Cable: This is the USB-to-serial programming cable specifically designed for Panasonic FP1, FP3, and FP5 PLCs.
- Panasonic PLC Software: You’ll need the appropriate programming software for your specific PLC series (FP1, FP3, or FP5). This software is used to write programs, configure settings, and communicate with the PLC.

- Connect the Cable:
- Plug the USB end of the USB-8550 cable into a USB port on your PC.
- Connect the other end (serial connector) of the cable to the programming port on your Panasonic PLC
- Install USB Drivers (if necessary):
- If your PC does not automatically recognize the USB-8550 cable, you may need to install the USB drivers provided by Panasonic.
- Launch PLC Programming Software:
- Open the programming software (e.g., FPWIN Pro for FP series PLCs) on your PC.
- Configure Communication Settings:
- In the programming software, configure the communication settings to match your PLC and the USB-8550 cable. This typically involves selecting the correct COM port (to which the cable is connected) and setting the communication parameters
- Establish Communication:
- Once the settings are configured, establish communication with the PLC by initiating a connection from the software to the PLC.
- This may involve options such as “Online” or “Connect” within the programming software interface.
