Yesterday, we experienced a Processor Failure which led us to open a new Processor, only to find that BootP was not functioning properly with it. After hours of troubleshooting, we stumbled upon a loose Processor in a drawer, which surprisingly worked on the first attempt. However, the model we are using (1769-L35E) is now considered obsolete. Our local AB distributor has recommended upgrading to the 5069-L320ER. We are wondering if the conversion process will be as simple as changing the controller in the project file or if it will require more extensive work. Our current setup includes 24vdc, 120 relay, and Analog I/O, along with 2 1769-AENTR Point I/O racks. We also have a similar machine with 2 (1734-ADN) Point I/O DeviceNet racks. Our OEM has offered the last available (1769-L35E) for $16K, causing us to consider alternative options for a backup plan. Any assistance from this community would be highly valued as we navigate this transition.
One of the easiest ways to upgrade from the L35E is by utilizing the 1769-L33ER controller. This option allows for a seamless transition without the need to adjust the I/O in the chassis. If opting for the 5069 series, you will need to either convert the existing chassis I/O to 5069 I/O (which can be challenging) or install a 1769-AENTR module to connect the chassis I/O to Ethernet. It is essential to ensure that you have at least RSLogix5000 v20, as this is the minimum firmware version supported by the L33ER controller. It is important to note that Point I/O modules belong to the 1734 series, not the 1769 series.
The distributor is honing in on the specific CPU part number, while the OEM is aiming to maintain their reserve of exact-match stock. Let me share an anecdote involving the PLC-4 and its role with the US Navy. I concur that opting for the 1769-L33ER (or a model with higher memory capacity) is the optimal decision, provided the application does not rely on the serial port. The POINT I/O, DeviceNet scanner, and other components will function seamlessly with it, just as they did with the 1769-L35E.
The Serial Port was previously utilized with a Modem but has since been disconnected. Further research will be done on the 1769-L33ER, which appears to be a promising option based on initial findings. A quick online search revealed that it is priced at 25% less than the original quote from our OEM. Thank you for your assistance and input.
I have upgraded multiple L35 programmable logic controllers (PLCs) with the newer L33ER model, a simple swap with the same I/O capabilities. The L33ER boasts increased memory and a faster processor, resulting in significant performance enhancements. I experienced a remarkable difference in one application where the L35 was struggling - online edits that previously took minutes now happen in seconds. The upgrade truly transformed the system's efficiency.
If you prefer to stick with your current system, we can fix the L35e for you to have a reliable backup. Sending both units will give you two backups, ensuring long-term peace of mind. While others may suggest changing components, your success with the L35e speaks for itself. Take advantage of our complimentary quotes by emailing us at [email protected] to learn more.
Going through a similar transition with my own systems, I would suggest considering the upgrade to the 5069-L320ER. While changing the controller in the project file can work in some situations, this upgrade might indeed require more extensive work due to the differences in architecture between the two models. For compatibility with your 1769-AENTR Point I/O racks, you might need to use the 5069-AENTR communication adapter to ensure undisturbed operation. Despite the need for additional effort and possibly new modules, it could give you a more sustainable long-term plan as compared to staying with the soon-to-be obsolete 1769-L35E. It could save costs too, since the proposed OEM price for the old module seems quite high. Always remember, future-proofing is often worth the initial investment and effort.
While the conversion process might not be as straightforward as just changing the controller in the project file, it isn't something extremely daunting either. The 5069 line does have a different backplane and power supply requirements, so you may need to plan for those adjustments. You'll need to set up your I/O in the new CompactLogix system and then import your ladder logic program, adjusting addresses as necessary. With your list of current components, it seems like everything has a 5069 series equivalent, so compatibility should not be an issue. Finally, on the cost part, the initial conversion might seem expensive, but the 5069-L320ER will be a more sustainable solution in the long run than forking out $16K for the last 1769-L35E. This is definitely something a lot of us in the forum have navigated so don't hesitate to ask more specific questions as you move along.
It sounds like you’ve had quite the ordeal with that processor failure! Transitioning from the 1769-L35E to the 5069-L320ER should be manageable, but be prepared for some additional steps beyond just swapping the controller in the project file. You'll likely need to update your I/O mapping and possibly adjust any specific instructions or configurations related to the new architecture, especially since you're working with Point I/O and DeviceNet equipment. I recommend reviewing the migration documentation from Rockwell for this upgrade—they usually provide valuable insights on what to expect. Also, consider reaching out to the OEM about your backup plan; they might have more suggestions with your current setup in mind. Good luck with the transition!
Upgrading from the 1769-L35E to the 5069-L320ER should be a manageable process, but it does involve some careful planning. While you might be able to simply change the controller in your project file, you will also need to account for differences in I/O modules and connections, especially since the 5069 series has a different architecture. It might be necessary to rewrite parts of your logic to accommodate the new functionalities or features of the new controller. Don’t forget to check compatibility with your existing 1769-AENTR and 1734-ADN configurations; you may want to reach out to your local distributor for specific upgrade kits or support. It sounds like a good time to also reassess your backup strategy, especially at that price point for the old model! Good luck with the transition!
