What type of memory backup does the CompactLogix 1769-L30ER utilize? Is it powered by a battery or does it rely on internal flash memory storage? Explore the memory options of the CompactLogix 1769-L30ER for your automation project.
CompactLogix controllers such as the 1769-L23x and 1769-L3x are equipped with a 1769-BA lithium battery. Unlike the 1768 controllers and the CompactLogix 5370 controllers, these models do not need a battery as they utilize internal nonvolatile memory to store their programs. The stored energy in the system ensures that the controller remains powered long enough to save the program to internal nonvolatile memory. However, it does not retain data on external storage devices such as the CompactFlash card or SD card.

Appreciate your help, Garry.
Battery-less Energy Storage Solution for CompactLogix 5370 Controllers...The controllers utilize an internal Energy Storage Module (ESM) as described by Garry. Additional relevant information includes several access levels for different features such as the CompactLogix Capacitor Backup and Power Up Sequence. RSLogix 5000 software also lists the Battery as a minor fault for CompactLogix 5370 controllers, accessible through TechConnect. Nonetheless, projects utilizing a 5370 CompactLogix controller may still encounter the "Battery" minor fault, which actually refers to an ESM fault rather than a Battery fault. This fault can be monitored through the FaultLog Object using a GSV to the MinorFaultBits attribute, bit 10. Since the ESM is not replaceable, encountering this fault would require controller replacement. In the event of a Major Fault Type 1 Code 40 in a Logix 5000 controller, it indicates a failure of the ESM to store the project to the internal NAND flash memory upon power up. This typically points to a hardware issue with the ESM not charging or retaining its stored energy. Minor Faults such as Type 10 Code 12, 13, 14, 15 also trigger the Battery Minor Fault and suggest ESM issues. Major Faults will halt the processor, while Minor Faults will not interfere with its operations. For further assistance, please refer to TechConnect. Thank you, George.
In regards to 1769 CompactLogix Batteries, the 1769-L23x and 1769-L3x controllers are equipped with a 1769-BA lithium battery. Contrarily, the 1768 controllers and the CompactLogix 5370 controllers do not need a battery. Instead, these controllers utilize internal nonvolatile memory to preserve their program during shutdown. The stored energy in the system ensures that the controller remains powered long enough to save the program to internal nonvolatile memory. However, the external CompactFlash card and SD card do not retain power. It is important to note that although the 1769-L3x and Compact Logic 5370 controllers may seem similar, they serve different purposes. Please let us know if you have any further inquiries regarding the necessity of the battery for these controllers. - Garry, ACC Automation.
When Nuko-san asked if the 1769-L3X and Compact Logic 5370 were the same, it sparked a discussion about the differences between the two. The CompactLogix line has gone through several generations, making it difficult to differentiate between older and newer controllers based purely on catalog numbers. For example, the 1769-L32E and L35E are considered "pre-5370" controllers and cannot be upgraded beyond version 20. On the other hand, the newer "5370" controllers like the 1769-L30ER and the 5069 series have been introduced to help alleviate confusion. So, while the battery may be required for certain controllers, it's important to understand the different generations of CompactLogix products to avoid compatibility issues.
The CompactLogix 1769-L30ER primarily uses flash memory for backup and doesn't rely on a battery. It's actually quite sturdy in design and allows for easy preservation of information during power outages or disruptions. It also excels in its ability to retain data even after being powered off. You can consider it a reliable option for your automation project, combining the durability of flash storage with the processing capabilities of the CompactLogix platform.
The CompactLogix 1769-L30ER primarily uses non-volatile memory for backups, relying on internal flash storage rather than a traditional battery. This means that it retains important program and configuration data even during power loss, making it a reliable choice for automation projects. Plus, the absence of a battery eliminates worries about maintenance and replacement, which is a real convenience for long-term operations.
The CompactLogix 1769-L30ER uses internal flash memory for its backup, which means it doesn't rely on a battery like some older systems do. This flash memory is quite efficient for retaining data during power loss and provides a reliable option for your automation projects. Plus, since it’s not battery-dependent, you don’t have to worry about battery lifespan or replacement, making maintenance easier and more cost-effective over time.
