Currently, I am developing a program in Studio 5000 version 36 using a 1769-L24ER-QBFC1B Series A PLC running Version 30. Initially, I planned to update the PLC to version 36. However, upon checking the downloads page, I found that version 36 is specifically for Compact Logix 5370, while the firmware for the L24 is still at version 30. Should I consider reverting to version 30 for my program? Are there any potential complications or issues if I attempt to downgrade the program file? Any advice on how to proceed would be appreciated. Thank you.
The best way to determine compatibility is by compiling different versions and checking for any unsupported functions. A simple method is to export programs from the tree under tasks by right-clicking on them one by one, and then import them into a new project. While saving files to a newer firmware is straightforward, downgrading requires an export/import process unless you're willing to edit the source XML files.
You can download the latest V36 firmware for your controller from the PCDC website.
One user, Contr_Conn, mentioned that the firmware can be found on the official RA website. Simply download and install it on your computer to have access to firmware updates and modifications.
Yes, you should consider reverting your Studio 5000 program to version 30 to match your PLC's firmware. If you try to run a program written on a higher firmware version like v36 on a v30 PLC, the program might not function as expected due to potential differences and enhancements between the two versions. While downgrading, note that you may lose some features or functions that only exist in the newer version. Therefore, make sure to back up your current program before downgrading, and carefully review the program for any missing features or changes afterward. It's always crucial to keep your PLC's firmware and program software versions in harmony to ensure smooth operation.
It sounds like you might be better off reverting to version 30 for compatibility with your current PLC. Trying to run version 36 on hardware that's only compatible with version 30 may cause unexpected behavior and could potentially even brick your PLC if there are major differences in the firmware. The downside is that you'll lose out on any new features or bug fixes introduced in the latest version. To proceed, you'd need to back up your current project, uninstall version 36, and reinstall version 30. Then, you can import your project and recompile your program to ensure it's compatible with version 30.
Yes, it would probably be the best move to revert your program to version 30 if that's what the PLC is running. Generally, firmware and the programs should ideally be the same version to ensure compatibility and stable operation. If you proceed with downgrading the program, remember to backup your existing project before starting, in case things don't go as expected. Also, re-test your entire program thoroughly after the downgrade. The process should go smoothly, but there can be unexpected oddities anytime you switch versions.
It's great that you're being thorough with your versioning! Since the 1769-L24ER-QBFC1B is capped at version 30, I would definitely stick with that unless you have a compelling reason to switch PLCs. Downgrading the program file to version 30 shouldn't typically cause issues, but it's crucial to review any features or instructions you've used that are specific to version 36, as they may not translate correctly or be supported in version 30. Always make a backup of your project before making any changes, just in case. Good luck, and don't hesitate to reach out if you run into specific challenges!
