We recently experienced a power loss on our PLC-controlled degreaser machine, resulting in a loss of memory and inability to run the PLC. The manufacturer has informed us that the battery on the CPU unit is non-interchangeable and we need to purchase a new unit with a built-in battery. Our concern is whether it is possible to replace the battery on the original CPU unit to avoid program loss. While we understand that attempting to change the battery may result in program loss, we are already facing this issue. We are seeking advice from anyone with experience on the Vipa CPU 314 ST Speed 7 model to help us determine the best course of action. Thank you for your assistance.
Are you wondering if there is a card inserted in the MMC slot? Consult the manual for instructions on how to load from memory. Access the manual at http://www.vipa.de/uploads/tx_sbdownloader/HB140e_cpu_314-6cf02_09-11_01.pdf and refer to page 36 for guidance. Wishing you the best of luck!

I appreciate the valuable information, thank you. Currently, there is no card inserted in the PLC memory slot. Is it possible to replace the onboard battery? If so, please let me know.
Is there a way to save the program directly to a memory card instead of relying on external access to the PLC? Our original program needs to be reinstalled remotely by the manufacturer, and we are wondering if there is a way to ensure it is saved to the memory card. Any assistance on this matter would be greatly appreciated. Thank you in advance.
Refer to pages 54 and 84 in the manual above. Are you equipped with the necessary software for these programmable logic controllers (PLCs) that are compatible with Siemens S7-300 and Siemens Step 7 Simatic Manager software, along with an MPI adaptor lead? Alternatively, consider requesting the manufacturer to send you a pre-programmed memory card for these PLCs. Regards, s.f.
If you correctly understand the question, the answer is yes - you can replace the battery while the CPU is on. Once you have loaded the program onto the CPU, you have the flexibility to swap out the battery for another. However, this is not possible when the power is off.
I sympathize with your ongoing headache. I've faced a similar experience with a different machine. While I don't have direct knowledge on the Vipa CPU 314 ST Speed 7 model, this problem seems more like a planned obsolescence by the manufacturer. However, if you are confident on the disassembly and reassembly process and your machine is out of warranty, it might be worth it to try and replace the battery yourself. Have you considered reaching out to a third-party electronics or PLC specialist? Sometimes, they are more flexible and might be able to help you figure out a workaround to prolong the life of your CPU unit. Also, remember to take this opportunity to look into regular backup solutions to avoid future program loss.
From what I've experienced with the Vipa CPU 314 ST Speed 7, the manufacturer is correct about the non-interchangeable battery. However, it's worth noting that you could potentially backup your PLC program before attempting any kind of hardware intervention so that you can reinstall it if the memory gets wiped. It's a risky endeavor, but it's an option if cost is a major concern. Always remember to follow safety protocols while proceeding with this. Ultimately, though, it may be more beneficial in terms of reliability and future support to purchase the new unit, especially if the old one is already exhibiting failures.
From my experience with PLC systems, especially the Vipa CPU 314 ST Speed 7 model, I agree the battery is indeed non-replaceable. However, there's a ray of hope - can you attempt a program backup? Even though you've lost power, the program might still be present if you haven't turned on the machine several times. A software called SPEED7 Studio can be used to back up your program. Regardless, for the long-term, considering a new unit might be better as these battery issues only compound over time. Also, routinely backing up your program can prove beneficial in avoiding such situations in the future. Just a suggestion, hope it helps!
From my experience with PLCs, it's indeed tricky when the battery dies and the manufacturer says it's non-replaceable. However, considering your current situation with the Vipa CPU 314 ST Speed 7, I'd suggest carefully exploring the possibility of replacing the battery yourself, considering you already face program loss. I've seen techs in similar positions who've successfully managed to do so, though it does require expertise and precision. Please remember, any attempt to replace the battery on your own might void your warranty. If your intent is to avoid recurring cost and hassles, you might also want to consider investing in PLCs that come with a replaceable battery feature in the future.
I totally understand your frustration with the power loss and memory issues on the Vipa CPU 314 ST Speed 7. Since the manufacturer has confirmed that the battery is non-interchangeable, it might be best to focus on how to back up your programs and settings for future scenarios, even if you choose to swap out the CPU. If you can access the program via the software, try to document everything before making any changes. Some users have also had success with creating a manual backup on their PCs, which could save you a lot of hassle down the line. Good luck, and I hope you find a quick solution to get your degreaser up and running again!
It's definitely a tough situation, especially since losing the program can be such a headache. While I'm not a Vipa expert, I would suggest checking for any service documentation from the manufacturer that might provide insight into whether the battery can be accessed safely. Some users have had success with using backup solutions or even manually saving their programs on a USB or using software interfaces—if you can, it might be worth exploring those options before committing to a new unit. Good luck, and hopefully, someone with direct experience can chime in!
