Does the Powermonitor 5000 transfer data directly to its display or does it need a PLC to act as a middleman? I am currently observing my first Powermonitor 5000 in a new installation, and it seems to be attempting to collect data from certain integer addresses, but encountering errors. The display is an 800 series HMI within an AB MCC system. While I would expect the Powermonitor and HMI to function independently, the display is only showing stars instead of data. I plan to review the manual later, but I am curious if the Powermonitor should be operational on its own or if a PLC connection is necessary.
There is no requirement for a PLC to act as a middleman. In order to make it function properly, it is advisable to refer to the user manual for instructions.
After fixing the IP addresses, everything functioned correctly as anticipated.
It's great to hear that you've got it working! The PowerMonitor 5000 does an excellent job at mimicking an A-B device in terms of CIP Assemblies and Data Table emulation. I haven't come across the PanelView 800-based MCC installations, but they seem interesting. I have a system with eight PM3000's that are a decade old and have had to deal with frequent storms and power surges, resulting in a yearly replacement of one unit (as well as various VFDs). I've developed cheat sheets for setting them up and transitioning my code from the old ControlNet interface to the new one.
The PM5000 display is essentially a rebranded 4” PanelView 800 model equipped with pre-made apps suitable for one, two, or three monitors. The HMI tags are configured to point to floating points, such as F53:3, which are detailed in the comprehensive Fabulous Manual. Depending on your specific requirements, you may utilize features like MSGs to retrieve data from various elements such as F53:3, F54:3, and F55:8 when working with our building management PLC. One standout feature of the display is its ability to capture waveforms, allowing users to remotely access and download event data using a web browser. It is crucial to note that only one CSV file should be downloaded at a time due to the generation process from compressed internal storage. Additionally, an Excel sheet has been created to visualize waveform data extracted from the CSV files, although certain details are proprietary. For effective waveform logging, it is recommended to periodically clear out old files by sending a value of 15 to F47:1. This can be accomplished through a PLC MSG or by integrating a button on the display interface. Furthermore, waveform files can be accessed via FTP, but they are designed for use with the FactoryTalk EnergyMetrix waveform viewer, which may not be available as a standalone component.
I believe I have a better understanding now. By entering the correct IP address, I am able to see numerical data. Additionally, I have noticed that there is an Add-On Profile (AOP) available for this, which likely records the F registers mentioned earlier into a Logix PLC. The fact that there are three versions of the application initially confused me, but your explanation clarifies things. I am unable to access the display using a web browser; it may be due to IT blocking that specific port. As for editing the screens, would FTVME be the appropriate tool to use?
From my experience with the Powermonitor 5000, it does need a PLC to function effectively. The unit gathers data, and then the PLC serves as an interpreter, converting the raw data into a decipherable format for the HMI to display. Hence, if you're seeing stars instead of data, it's likely a communication issue between your Powermonitor, PLC and HMI. Try reviewing the IP configuration and ensuring that the PLC correctly interprets the data from the Powermonitor according to the register addresses.
Your intuition is correct! The Powermonitor 5000 does indeed function independently when it comes to data collection. However, for the data to be displayed on the HMI, typically a PLC is used as a protocol mediator to interpret the data from the Powermonitor and translate it into a format that the HMI can understand and display. This is probably why you're seeing stars instead of data on your HMI; it may indicate a communication issue between the devices rather than a problem with the Powermonitor itself. It would be wise to review the communication link and protocol setup among the Powermonitor, the PLC, and the HMI.

Answer: Answer: The Powermonitor 5000 typically communicates directly with the display, such as the 800 series HMI, without the need for a PLC intermediary.
Answer: Answer: Errors during data collection could be due to incorrect configuration settings, communication issues, or misalignment of data formats between the Powermonitor 5000 and the HMI. Troubleshooting these aspects may resolve the issue.
Answer: Answer: The Powermonitor 5000 is designed to operate independently and does not necessarily need a PLC connection to function within an MCC system. However, proper configuration and communication setup are essential for seamless data transfer to the HMI.
