For the past two days, I have been researching extensively about the P_LLS system, but I am struggling to grasp how the system handles swaps beyond two pumps. I comprehend the concept of creating an array tag for each motor and linking it to the "Ref Motors" tag in the LLS. However, the issue arises when the Ref Motors tag only accommodates two array spots. How can I seamlessly connect a third, fourth, or fifth pump to the LLS system?
Are you asking about the limitation of having "only two spots" in an array? It is possible to modify the array size according to your needs.
For valuable insights, be sure to check out Chapter 2 on page 107 of the document available at the following link: https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/proces-rm013_-en-p.pdf.
Cardosocea inquired about the meaning of "only has two spots" in relation to array size adjustments. The "Ref_Motors" tag array in the P_LLS system is designed to accommodate only 2 motors, specified as datatype P_LLS_Motor[2]. This means that even if a 5 motor array tag, with datatype P_LLS_Motor[5], is linked to the "Ref_Motors" tag, it will only recognize the first 2 motors.
DarrylR shared a valuable resource on motor integration for industrial processes that you may find useful. Chapter 2 of the document (page 107) contains insightful information on this topic. However, after reading through it, it seems there may be a lack of detailed explanation on how to connect additional motors beyond the first two. Rest assured, the information is likely there, but may require closer examination to uncover.
Were these configurations set as follows: P_LLS.Cfg_NumMotors: 3, P_LLS.Cfg_MaxDemand: 2, P_LLS.Cfg_MinDemand: 0, and P_LLS_Motors[xx].Sts_Available: 1?
It sounds like you're on the right track with the P_LLS system. To handle swaps with more than two pumps, you might consider creating a separate array for additional motors and then linking those to the main Ref Motors tag. You can use indexing to refer to them based on your operational needs, allowing the LLS to recognize and manage all pumps in the system. Additionally, check if the system supports sub-arrays or a dynamic tagging system, which could help you integrate multiple pumps more efficiently. It’s all about how you structure your tags!
It sounds like you're diving deep into a complex system! If the "Ref Motors" tag is limited to two array spots, you might want to consider creating a secondary reference for additional pumps. One way to do this is by using a hierarchical structure where you group the pumps in batches or utilize a combination of arrays to manage them collectively. Make sure each motor’s tag is properly indexed, and consider using a state machine approach to manage pump swaps dynamically. This way, you can effectively simulate more than two pumps even if you're constrained by the initial tag limit. It might also be worth checking the documentation for any configuration settings or workarounds that allow for scaling beyond two pumps. Good luck!
It sounds like you're diving deep into the P_LLS system! One approach you might consider is looking into the tagging system and how it can incorporate dynamic arrays or configurations that allow for more than just the referenced two motors. If the system's limits stem from how the Ref Motors tag is structured, you might need to explore creating a more flexible array or using a different tag structure that can adapt as you add pumps. Sometimes, modifying the configuration settings or using sub-tags for additional pumps can also help. Have you checked the documentation for any guidelines on extending beyond the default settings? It might shed some light on potential workarounds!

Answer: Answer: To connect more than two pumps to the P_LLS system, you can create additional array tags for each motor and then link them to the "Ref Motors" tag in the LLS. While the default setup may only accommodate two array spots, you can extend the functionality by appropriately modifying the tags and configurations.
Answer: Answer: If the "Ref Motors" tag in the LLS system limits the number of array spots to two, you can work around this limitation by adjusting the system configurations or utilizing alternative methods to connect a third, fourth, or fifth pump. This may involve customizing the tags, reconfiguring the system settings, or seeking support from the system provider for advanced solutions.
Answer: Answer: While the P_LLS system may have default limitations on the number of pumps that can be directly connected, you can refer to the system documentation, consult with experts in the field, or explore advanced configurations to efficiently handle multiple pumps. Implementing structured tagging, ensuring compatibility with the LLS system, and testing the connections thoroughly are recommended practices for seamless integration of additional pumps.
