There is a new Micro 850E model that offers the capability for implicit messaging with a Kinetix 5100 servo and a Powerflex 525 drive. Despite my best efforts, I have been unable to locate any specific guidelines on how to execute this task. This is further compounded by my lack of experience with implicit messaging and Logix 5000 programming. While I possess proficiency in the Micrologix family and RSLogix500, it seems inadequate in this scenario. The manual for the Kinetix 5100 outlines the setup process in Logix 5000, which I have attempted to follow without success. Rather than employing add-on instructions, the process involves utilizing UDFBs. I have successfully downloaded and configured the UDFBs for the modules, but I have hit a roadblock in terms of connecting them effectively, as there is no accompanying assembly instruction for the UDFB. If anyone has prior experience in accomplishing this task, I would greatly appreciate any guidance or insights. Thank you, Chuck.
If you're looking to add PowerFlex 525 drives to your Micro800 PLC program, I recently experimented with this and documented my findings for my team. A crucial tip is to refer to chapter 8 of manual 2080-UM002 for detailed instructions on this process. Key points to remember: Both Micro850 and Micro870 PLCs support Explicit messaging over ethernet, but only the newer Micro850 (2080-L50E) and Micro870 (2080-L70E) models are capable of Implicit messaging to ethernet devices. This functionality enables seamless communication with PowerFlex 525 drives. Each Micro800 PLC (2080-LX0E) can manage up to 8 PowerFlex525 drives. Ensure that the PLC has the letter "E" in the part number, runs on firmware version 21.011 or later, and uses Connected Components Workbench version 21 or later. To incorporate PowerFlex 525 drives into your Micro800 PLC program, consult Chapter 8 of 2080-UM002 for step-by-step guidance. Essentially, you must access the Controller in the PLC program, navigate to Ethernet>Modules, and add each drive you wish to control by specifying its IP Address, revision number, voltage, and power rating. For enhanced convenience, leverage User Defined Function Blocks (UDFB). Download the "PowerFlex52x UDFB Library" from the Product Compatibility Download Center and import it into your PLC program. This will introduce function blocks that facilitate VFD control. When implementing the UDFB in your ladder logic, ensure that you map the input and output parameters correctly. Remember that sending a stop signal is necessary to halt the motor, as simply removing the start signal allows the motor to continue running. Further, note that the parameters for the VFDs are not stored in the PLC program but within the drives themselves. You will need to input details such as IP address, acceleration/deceleration rates, speed references, Full Load Amps (FLA), voltage, etc., directly into the drives.
Are you able to purchase the 850E model now? According to my distributor, it was initially expected to be released in May.
Thank you for providing such an excellent overview of the 850E controller's key features and documentation. Your insights are truly valuable!
RedDraw asked if it was possible to obtain the 850E model, as their distributor initially mentioned it wouldn't be available until May. In late November, they received a quote for both the 2080-L50E and the 2080-L70E models, with a projected "end of May" availability for the former and a two-week wait for the latter. However, the distributor now shows limited stock of L50E-24QBB and L50E-48QWB models, as well as low stock levels for some L70E variants.
A big thank you to jridge for providing a detailed overview of the implicit messaging capabilities of the Micro850E PLC. I am looking to expand on this by integrating Ethernet 842E encoders into the system. Can anyone confirm if it is feasible to communicate with an 842E encoder? I am in the process of transitioning PLC control for the OEM I am employed with, moving from ML1400's to the Micro 850 (2080-L50E).
Hi there Chuck, it sounds like you have really been digging into this! Implicit messaging can indeed be challenging when you're new to it. Have you tried reaching out to our friends over at Rockwell Automation? Their tech support has helped me solve some pretty tricky programming issues in the past. Also, consider checking out a few online tutorials or forums dedicated to Logix 5000 -- the PLC programming community is pretty supportive. I remember reading a detailed post somewhere about the methods of integrating Kinetix servo drives with the Logix 5000 and it helped me a lot with UDFBs. It may take some digging, but those resources really saved me a ton of hours in trial and error. Keep at it, and I'm sure you'll get it mastered in no time!
Hey Chuck, I empathize with your struggle. It sounds like you're navigating some complex operational territory with these various technologies. My suggestion would be to not skip the utilization of add-on instructions in your setup, despite the absence of assembly instructions for the UDFB. In addition, as you dig further, potentially consider reaching out directly to the manufacturers for guidance. Their technical support teams often possess a wealth of information that isn't readily available in the manuals. Finally, don't underestimate the value of your proficiency in Micrologix and RSLogix500. Incorporate that knowledge into this new challenge; you might find you're more capable than you think. All the best!

Answer: Answer: Implicit messaging allows communication between devices without explicit messaging instructions. To set it up with the mentioned components, you need to follow specific guidelines in Logix 5000 programming.
Answer: Answer: UDFBs (User Defined Function Blocks) are used instead of add-on instructions in the setup process. They are downloaded and configured for the modules to facilitate communication between the devices.
Answer: Answer: Connecting the UDFBs effectively requires following assembly instructions, which might be missing in the manual. Seeking advice from experienced individuals who have accomplished this task before can provide valuable insights.
Answer: Answer: Proficiency in the Micrologix family and RSLogix500 is beneficial but may not be sufficient for this scenario. Seeking additional resources, training, or guidance from experts in Logix 5000 programming can be helpful.
