  1. Hi all, 

    May I know why I using FX5U built in RS485 received other device data, the data unstable, always jumping, just received only no need sent out any data.(protocol type is non-protocol)

    I use PC to monitor received the data, e.g first byte is 0A, my PLC received 1000, sometimes jump to 500, I don't know why, but I use FX3U all is ok, very stable, anybody have facing this issue before ??

    Then always have error light lit up, I use PC to diagnose the alarm message is framing error, parity error, I have change to different parity but still same, the third party device default parameter is 8bit data, 1 stop bit, even parity, 19200 baud rate.
