Hello everyone, I am in possession of an AB ControlLogix 5580 PLC. When I use my USB to scan it, an error message stating "NVRAM bad" appears. What steps should I take to address this issue?
Could you please provide a screenshot for clarification? It is important to specify if you are referring to the Windows Device Manager, RSLinx utility, or RSLogix5000 studio. The more information you give, the better chance we have of finding a solution.
I attempted to connect using both USB and Ethernet cables, successfully pinging the PLC. However, I am unsure of the process for installing firmware. Can you guide me through this step?
I'm facing a roadblock as my ControlFlash software does not have the PLC catalog number I need. This is hindering my progress and causing frustration.
TechConnect recommended upgrading to ControlFlash version 15.7 for optimal performance.

Hi there! The "NVRAM bad" error typically suggests an issue with the non-volatile RAM in your PLC. This part stores important data that persists even when power is disconnected. I'd start by checking whether your firmware is updated or not, as outdated firmware can sometimes cause similar issues. If the PLC is under warranty, you might want to have AB look at it. If not under warranty, consult with a technician who can diagnose the problem - replacing a faulty NVRAM could be the last resort. Also, don't forget to regularly backup important data!
Hey there, sounds like you're dealing with a potentially troublesome issue. "NVRAM bad" generally indicates a hardware problem. However, before jumping to conclusions, try the power cycle; simply power off, wait for a few minutes, and then power back on. If that doesn't work, then sadly, you might be looking at replacement of the controller as ControlLogix controllers don't have user-replaceable NVRAM. Be sure to check with Rockwell Automation Support for official advice - they're really helpful, and they might have other suggestions or a fix that doesn't require a full replacement! Good luck!
Hey there, it seems like your NVRAM might be throwing that error due to a fault or corruption. You could try a simple reset first. However, if the issue persists, it may indicate a hardware problem with the NVRAM module itself. In such a case, it would advisable to reach out to Rockwell Automation's customer support or a reliable technician. They could guide you further in addressing the issue, perhaps even suggesting a replacement if necessary.
Hey there, it sounds like your NVRAM (Non-Volatile Random Access Memory) may be failing or corrupt. This typically holds the PLC's important boot up details and configuration settings. To solve this, your best bet is probably to backup all important configuration files you may need, then replace the damaged NVRAM chip. However, given the intricacy of this task, I'd suggest engaging with a professional or contacting Allen Bradley support to guide you further. Hope this helps!
