I am currently using an L33ER PLC with version 21.11 firmware. However, I do not have this specific version on my computer and it seems to be unavailable for download. In order to update the firmware, I have a copy of the offline program, but I first need to perform an online upload to retrieve the current tag values. Is there a way for me to accomplish this task without access to version 21.11?
Typically, it is important for the software version to align with the firmware version in the Programmable Logic Controller (PLC). I have noticed that the latest version available for download is v21.03.02. I believe this version should be compatible. Is it possible that you have a different v21 version installed that is causing issues?
If you are looking to download version 21, you may need to request it as it may not be readily available. Just recently, a similar inquiry was posted on this platform.
After some trial and error, I have realized the solution. Rather than attempting to connect online, I opted for the "upload" option. A prompt confirmed that it would convert the file during upload. Also, it's important to note that V21.03 is not supported by V21.11. Thank you for the help.
The latest software updates, V20 and V21, have been causing headaches for users. The compatibility issues between different minor releases within versions 20 and 21 are likely the root of the problem you are experiencing. For a more detailed explanation, refer to SeeID: IN8221.

In general, smaller updates are usually compatible with existing versions. However, a security update in versions v20 and v21 caused compatibility issues when moving from the .01 revision to the .03 revision. While v20.04 addressed this problem, v21 did not receive a similar fix. As Ken Roach humorously pointed out, software managers can get just as excited about minor version updates as a cat with catnip. The peculiar addition of a leading zero in version numbers like v21.011 can be puzzling to users, and the complexities of sub-revision numbers can be confusing. Shawn Tierney's explanation sheds light on why the ".03" revisions in Studio 5000 v20 and v21 are not compatible with the ".01" revisions. If you are using firmware version 21.11, which predates the compatibility-breaking update, you will need a compatible software version like v21.00.04. Before installing a new version, ensure to uninstall any existing versions. Upgrading the firmware is recommended to avoid compatibility issues. If upgrading, a higher software version than the existing one can be used for online operations, with the software automatically converting files to the installed version.
Yes, there is. You can straightaway use the offline program, no need to bother about the current tag values. However, be aware that you won't get the current live values, but rather what was last saved in the offline program. Before doing this, ensure to backup your current program just in case anything goes wrong with the firmware update. After successfully updating the firmware, you may then need to perform an online upload to retrieve the current tag values. Also, contacting tech support for version 21.11 - they might provide you a temporary solution or an alternative way to upgrade your firmware without disrupting your current settings.
You may not need to have the exact version of firmware 21.11 on your computer to access and retrieve tag values. Many times PLCs can communicate with different version levels of firmware, especially if the differences are minor. Try using the version you have on hand and, if that doesn't work, you could consider reaching out to the PLC's manufacturer or a technical community for additional guidance. They may have some insights or workarounds to access that specific version of firmware.
Absolutely, you have a couple of alternatives. Firstly, you can try to use RSLogix5000's "Upload with version conversion" feature. This allows you to upload the program from your L33ER PLC into a different version of RSLogix5000 that you do have on your computer. A second option is to connect remotely to a computer that does have the desired version installed. Just make sure you have the necessary permissions and a steady internet connection.
