Hello, I'm currently working with an FX1N-60MT and an FX2N-2DA expansion module. I have two output channels configured from the 2DA to regulate my output voltage, with an input range set between 0 and 4000. I've implemented the same code for both channels. However, I'm encountering an issue where only channel 1 allows me to output any desired value. Specifically, when I input an odd number (for example, 1597 or 2789), channel 2 successfully outputs that value but then fails to adjust thereafter, remaining fixed. Could you help me identify the potential error causing this behavior? Thank you very much!
For optimal assistance, it would be beneficial to share your program as a reference. You can explore the linked manual for a comprehensive example. Visit the following resources: [PLC Talk Discussion](http://www.plctalk.net/qanda/showthread.php?t=55961) and [Mitsubishi Electric Manual](http://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy992d74901/jy992d74901g.pdf). Best regards!
It sounds like you're dealing with a confusing behavior there! One possibility is that the output configuration for channel 2 might not be set up the same way as channel 1, even if the code is identical. Sometimes, parameters like scaling, range, or even the output mode can differ between channels in the module settings. I'd recommend double-checking the configuration settings for both channels in your programming environment. Additionally, look into any potential wiring issues or interference that could be affecting channel 2’s response. If that doesn't reveal the problem, you might consider adding some debug outputs to see how the values are being read and written on both channels during execution. Good luck!

Answer: - Verifying the code logic and ensuring both channels are addressed correctly. - Checking all physical connections and wiring for channel 2. - Testing the module with another output device to determine if the issue is with the module or the connected equipment. - Updating the module's firmware to the latest version. - Consulting the module's documentation for any specific configuration settings that might affect channel 2.
