After programming my Mitsubishi FX3G PLC and successfully downloading the program, I encountered a communication issue when connecting the Mitsubishi FX2N-4DA expansion module. The PLC froze and stopped responding, causing a disruption in the system.
I have an older A/D unit and I am unsure if it is compatible with FX3 PLCs. To ensure compatibility, you should consider using a FX3U-4LC module.
While the functionality should be operational, there may be an issue with the implementation of the FROM/TO commands.
While I have successfully utilized the FX2-4DA module on the FX3U PLC, I have not yet tested it on an FX3G. However, based on feedback from other users like goghie, it is believed to be compatible.

Sounds like a frustrating issue you're experiencing! Noticing you're using an FX3G series PLC, is your PLC firmware up-to-date? Compatibility issues might occur with older firmware versions when connecting the FX2N-4DA expansion module. It's worth considering, because this mismatch could be causing the communication errors. Also, double-check your wiring since wrong wiring can often lead to PLC malfunction. Hope this helps!
