Is there a way to expand memory capacity in an Allen Bradley Compact Logix 1769-L32E controller? I am looking to make adjustments to a processor that is currently operating with memory levels in the red zone. Thank you.
The memory capacities of CompactLogix and ControlLogix 1756-L6x controllers are set and cannot be adjusted. If you're unable to free up enough memory by removing unused tags or condensing unused arrays, consider upgrading to a 1769-L35E controller. Switching controller models is a straightforward process - simply choose the new controller model in Controller Properties. By sticking with the 1769 Ethernet controller range, there will be no alterations to the I/O configuration. Upgrade to a 1769-L35E controller for increased memory capacity.
Ken, it looks like the boss will need to allocate funds for this project.
Upgrading your CompactLogix L32E to an L35E to address low memory fault issues is a straightforward process. Simply select the new controller model in Controller Properties, as recommended by Ken Roach. Since both controllers are in the 1769 Ethernet family, there will be no changes to the I/O structure. To begin, ensure that the L35E is connected to the same network as your current controller. Then, follow Ken's advice and make the switch in Controller Properties. If you're feeling hesitant, seek further guidance to avoid any potential mishaps in your system.
When asked for advice, TheHoneybadger recommended changing the controller type in the offline file before downloading it. It is suggested to make a backup of the original program before proceeding. Changing the controller type from L32E to L35E should not cause any issues. Ensure the new controller has the necessary firmware before downloading the program. In case of any problems, you can always revert back to the L32E controller.
Thank you, Patrick, for your advice. I am currently facing challenges in communicating with the L35 controller. Despite my initial expectations, setting up communication has proven to be more difficult than anticipated. My usual approach involves connecting over serial, but I have encountered my first obstacle in configuring the serial port. To troubleshoot, I connected to the L32 and confirmed that my cable and connections are working fine. However, I am still unable to establish a connection with the L35. It is worth noting that I purchased the L35 and other modules second-hand and have not yet used it. Despite successfully establishing a connection with the L32 using the same setup, I am unable to communicate with the L35. I tested the ethernet cable by connecting a crossover cable between my PC and the L35, and the link status light indicated a solid green connection, suggesting that the communication is functional. However, I am struggling to determine the IP address required to make changes.
Unfortunately, the memory of an Allen Bradley Compact Logix L32E controller cannot be physically expanded or upgraded because it's hard-wired to the device. It comes with a fixed memory that cannot change. However, you could potentially optimize your logic or programming to run more efficiently in order to free up some memory. Additionally, look at what's in your code. If there are unnecessary components or sections that aren't needed, removing them could help alleviate your memory issues.
Unfortunately, the Allen Bradley Compact Logix 1769-L32E's memory cannot be physically expanded as it's built into the hardware. However, optimizing your program can effectively free up some memory. For instance, monitoring the program for unnecessary loops or redundant routines and consolidating or rewriting these sections of the program to be more efficient may help. Also, consider any non-essential functionalities that can be removed. Another workaround could be migrating to a controller with a higher memory capacity if optimizing your program is not enough.
