Encountering problems while adding extra Powerflex 753-ENETR to the ethernet module list in Studio 5000 v31.01.00 Pro Edition is causing concern. With already 5 units and 2 Endress Hauser Liquiline 444 units connected to a 1769 L30 ER rev31.011 PLC, the question arises whether there is a limit on the maximum number of VFDs on one PLC or if this is a software glitch? The Node list allows for a maximum of 16, but only 7 have been utilized so far.
What specific error message are you receiving or what exactly is occurring? There appears to be no limitation on the number of Variable Frequency Drives (VFDs) that can be connected to a Programmable Logic Controller (PLC), except for the number of communication connections available.
Thank you for your response. I apologize, but it seems that an unexpected error has occurred within the software. Some potential solutions to resolve this issue include restarting the application, restarting your computer, or reaching out to our technical support team at [email protected] If you are experiencing unexpected errors, please follow these steps to troubleshoot and resolve the issue promptly.

emomorales mentioned: Thank you for responding. I encountered an Unexpected Error with the software. The Potential Solutions include restarting the application, restarting the computer, or contacting Tech Support at [email protected] Could this be a software issue with Studio, specifically with version 31? I have heard that significant changes from versions 30-32 have caused various issues, and I believe version 31 was particularly problematic.
Want to troubleshoot why your drive isn't showing up on your laptop using RSLinx? One common first step is to check the settings on your 753-ENETR module. Make sure the last octet on the card is set to a unique address that differs from the others. Additionally, make sure the firmware on the drive matches the AOP selection. It's possible that the firmware on the drive is higher than the others, so it's important to have all drives at the same firmware level for optimal performance.
Jim3846 suggested using a laptop or RSLinx to check if the drives are visible. This is a common first step in resolving drive visibility issues. The 753-ENETR may have additional settings, with the last octet needing configuration to ensure a unique address. The firmware version of the drive can impact the AOP selection. It's important to have all drives at the same firmware level for consistent performance. Currently, the drives are not installed, and the focus is on completing the programming beforehand.
I don't think there's a hard limit on the number of VFDs per se. I believe the issue is possibly about the total size of I/O data allocated for each module within your PLC. Since every ethernet module consumes a certain amount of I/O data, you might run out of capacity when adding too many modules. You might want to check the I/O size in the controller properties in Studio 5000. If that turns out to be the problem, you could perhaps decrease the RPI on your ethernet modules to free up some I/O space. Remember to plan your system regarding input and output needs to prevent these situations.
As far as I'm aware, there is no set limit on the number of Powerflex 753-ENETR or similar units that a PLC can handle. It more so depends on the complexity of your network, the processing power of your PLC, and how much data it can handle rather than the number of connected devices. It sounds like you might want to try troubleshooting your software first, perhaps performing a clean reinstall if necessary. Alternatively, it could be a compatibility issue due to the mix of Endress Hauser Liquiline units and Powerflex 753-ENETR in your configuration. So, remember to check for firmware compatibility as well.
