In a critical environment, I have a redundant L82 system set up and need to download numerous programs without compromising functionality. Could someone guide me on the proper process for this? I am unsure which system to download to first as I lack experience with redundancy. Additionally, how should I approach updating module firmware in this setup? Are there any specific considerations I should be aware of?
I have extensively researched redundancy setup, but I am still unclear on the download process. The instructions state to treat the primary rack/processor as a single non-redundant system in RS Logix. Does this mean that when I download to it, my process will stop as usual, or will the secondary rack seamlessly take over? How smooth will this transition be?
When transferring a program to the Logix Redundancy, a bumpless transfer is not possible. The process will come to a halt during the download.
Looking to effortlessly incorporate a new routine into your schedule without any disruptions?
Ken Moore asked if it is possible to add a routine without pausing and the answer is yes.
You can make online edits and import Routines, AOIs, and rungs without interrupting operations. However, downloading updates is not possible while the program is running.
When dealing with a redundant L82 setup, I'd recommend downloading and testing the programs one by one, beginning from your non-standby system. In this way, if any issue arises, it won't disrupt the overall operational flow. As for firmware updates, always update the standby module first. After verifying it operates correctly, repeat the process on the active module. Be aware of your system automatically performing a switchover after updating the active module, as it recognises it as 'faulty' due to differing firmware versions. To prevent any unnecessary downtime, temporarily disable automatic switchover before the update. You might also want to back up your programs before starting.
I'd suggest you start by downloading the programs to your less critical L82 system first. This serves as a useful 'test run' to check if the downloads impact any functionality. Then, proceed to the primary system. Concerning the module firmware updates, it really depends on the specifics of your redundant setup. However, typically, it's wise to apply the updates to the backup system first to test stability before updating the primary system. Keep tabs on your failover performance during this phase. Remember not to run simultaneous downloads in a redundancy setup as this could potentially overload the system. Always take one step at a time with these things!
From my experience working with redundant systems, I've found it's often safer to download programs to and update the firmware on the Standby system first. This way, if an issue arises during the process, your Primary system is still operational and can maintain your critical environment. Post-download/-update, you'd then need to manually toggle the Primary to Standby and vice versa. As far as considerations, ensure that both systems are compatible with the updates and that the Standby system is fully operational before switching roles. It's all about maintaining that seamless fallback safety net.
Absolutely, happy to help! When managing a redundant system like L82, it's commonly recommended to deal with the secondary system first. This minimizes the risk of bringing down your main system, ensuring 24/7 operation. For updates or new software, install on the secondary system and once you've confirmed success, replicate on the primary system. With firmware updates in a redundant setup, it's vital to maintain identical firmware versions across both systems to prevent any incompatibility issues. Perform your updates during a maintenance window if possible, to mitigate risks. Don't forget to backup your setups before starting the update process!
When working with a redundant L82 system, it's crucial to handle updates carefully to avoid any downtime. Start by downloading programs to the secondary (or standby) system first. This way, if anything goes wrong, your primary system remains fully operational. Once you've tested the updates on the secondary system and confirmed they're running smoothly, you can switch over and update the primary. As for module firmware, ensure that you check for compatibility with your existing setup and back up all configurations before proceeding. It might also help to consult the manufacturer’s documentation for any specific update sequences or precautions tailored to redundancy scenarios. Good luck!
