The FX2N 422 BD is a communication board designed to enable RS-422 communication for Mitsubishi FX series PLCs, allowing them to interface with other serial devices.
To connect the FX2N 422 BD to a PLC, you need to attach it to the left side of the FX series base unit and secure it with screws, ensuring proper alignment with the connectors.
Check the physical connections, ensure the communication parameters match between devices, verify the PLC program settings, and inspect the wiring for any damage or loose connections.
Regularly inspect the unit for dust and clean it with a dry cloth. Ensure all connections are secure and check for any signs of wear or damage.
The FX2N 422 BD is specifically designed for Mitsubishi FX series PLCs and compatibility with other brands is not guaranteed.
The FX2N 422 BD does not have firmware that requires updating; it is a hardware communication interface.
The maximum communication distance for RS-422 using the FX2N 422 BD is typically around 1200 meters, depending on the environment and cable quality.
Communication parameters such as baud rate, data bits, and parity need to be configured in the PLC program using the appropriate communication function blocks or instructions.
Ensure the unit is not enclosed in a confined space, check ventilation, and verify that the ambient temperature is within specified limits. Power off the system and allow it to cool before restarting.
No special tools are required for installing the FX2N 422 BD, but a standard screwdriver is necessary to secure the unit to the PLC base.
