If a communication error occurs with the Panasonic Controller via RS-232C, it could be due to incorrect connections or settings. Start by verifying the system register settings and ensuring they match the allocated communication port number. If using the PLC link function, confirm that the link areas do not overlap. Also, check the connection with the destination device, ensuring the SD terminal of the destination device is connected to the RD terminal of the PLC side and vice versa. Make sure the SG terminals on both devices are connected.
