The photo shows that the Internal State of the input module is Unconnected. The OA module located on the same chassis is displaying a similar message. The components in sequence are the L35E, IA module, 24 VDC power supply, and OA module. Possible issues could be a faulty module or a poor pin connection. What could be causing this issue?

If you suspect a malfunctioning module, be sure to conduct a thorough inspection. Verify that the end cap is securely installed and ensure that the tabs locking the cards together are fully engaged.
Unfortunately, there is no end cap included in the order. Thank you for your understanding. (A rookie mistake made by a beginner.)
dmroeder recommended ensuring that the tabs locking the cards together are securely in place. It is important to reseat them all to avoid issues, especially with the CompactBus. This type of problem is common and can be easily resolved by simply opening and closing the tabs. Make sure to remember this tip for future reference.
It seems like you've already highlighted potential issues with a faulty module or poor pin connection. Additionally, it might be worth checking the cabling between these modules for any damage or disconnects. Sometimes, power fluctuations can also cause modules to lose connection temporarily. It could also be a configuration problem on the L35E, where the backplane communication is not set correctly. If everything physically appears okay, I'd recommend checking settings or potentially updating firmware as a next step.
It seems like you've already nailed down some possible culprits: a faulty module or a pin connection issue. However, if both the input and OA modules are reporting being unconnected, it could also be a power supply issue. Interference or improper voltage from the 24 VDC power supply might be causing this. Do check your power supply health and make sure your wiring is correct and secure. It's also worth checking if there's any firmware that needs updating, as sometimes these glitches can be software related. Good luck with your troubleshooting!
This issue could indeed be due to a faulty module or poor pin connection as you suggested, but it may also be due to insufficient power supply. Since both the OA and IA modules are showing similar messages, it may be that the 24 VDC power supply isn't delivering enough power for both modules. I advise checking the voltage levels to ensure they're in the acceptable range for these modules. If the power supply isn't the root cause of the issue, then you'll have to examine the connection and the modules themselves more closely.
It sounds like you've covered some key possibilities already! Beyond faulty modules or poor connections, it might be worth checking the power supply voltage to ensure itβs stable and actually delivering 24 VDC, as fluctuating power can wreak havoc on module performance. Additionally, inspecting any wiring for damage or corrosion could reveal hidden issues that might not be immediately apparent. Good luck troubleshooting!
