Hello everyone, I am in the process of setting up a test bench and have come across an old L24-QBFC1B module. After updating the firmware to v30, I attempted to run a "Test Bench" program using my version of Studio. In the future, I plan on incorporating multiple expansion IO modules in addition to the existing embedded IO. Despite powering up the controller and flashing the firmware, the embedded IO is not functioning properly. I have only connected power to the controller and have created a basic L24 program with embedded IO configuration. I attempted to test the inputs and outputs using push buttons and a stack light, but the controller is not detecting any embedded IO. I even tried using a separate power supply from AB, but to no avail. Could this issue be the reason why the controller was listed in the "do not use" pile? The module fault I am encountering indicates an invalid link address (16#0312). How could this error occur with embedded IO? Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!
If you are encountering an error, it could be due to a missing or incorrectly attached 'End Cap', or loose/unlocked/bent pins on the IO connectors. Make sure to check these components to ensure they are properly connected. If not, your device may truly belong in the junk pile as indicated.
In a recent discussion, dmargineau pointed out that a common issue leading to errors in devices is the improper attachment of 'End Cap' and loose or bent pins in IO connectors. It is important to ensure the proper connection of removable terminal blocks to the IO pins to avoid such errors. If you are experiencing issues, it is worth checking the tightness of all pins to rule out any connectivity issues. Your support in troubleshooting is greatly appreciated!

Oh, I wasn't aware that was required. I will make sure to have one installed and provide you with an update. Thank you!
Hey there, it sounds like you're dealing with something tricky. This is purely conjecture but from the symptoms you described, the L24-QBFC1B module may have its embedded IO ports damaged or unserviceable, which may be the reason it ended up in the 'do not use' pile. The error code 16#0312 usually signifies some issue with how the processor is reading the embedded IO - possibly related to backplane communication between the processor and IO module. This can happen due to a host of reasons - faulty wiring, hardware issue with the board itself, or even an incorrect configuration in Studio. I'd suggest digging a bit more into the hardware aspect since you've already flashed the firmware. Also, check if the Studio configuration matches the exact physical hardware setup. Sometimes, the smallest details can make a big difference.

Answer: Answer: Updating the firmware may sometimes lead to compatibility issues with existing configurations. Double-check the firmware version compatibility and consider reconfiguring the embedded IO settings.
Answer: Answer: The invalid link address error could indicate a mismatch between the configured IO address and the physical connection. Verify the IO addressing in your program and ensure it matches the physical setup.
Answer: Answer: Check the wiring connections for the embedded IO modules, ensuring they are correctly wired and powered. Also, review the embedded IO configuration in your program to ensure it aligns with the physical setup.
