I am currently trying to connect to an older Schneider Electric Momentum Unity M1E PLC (171 CBU 980 91) and am in need of the Modbus/TCP register mapping. Can someone assist me in locating this information?
The 'register map' of a Momentum CPU is determined by the program loaded onto the PLC, with data stored in registers assigned during programming. If the original programmer is unavailable and the 'source code' file is missing, it can lead to a serious issue. While older Momentum models may have had memory limitations hindering program download/upload, modern PLCs have improved this aspect. If needing a 'register map', information can sometimes be gleaned from an HMI on the system. Momentum made waves as an affordable CPU with an Ethernet port and open protocol. Prior to Unity, Concept software was used, albeit with some cumbersome aspects such as separate DFB development. Configuration of Ethernet IP addresses on Momentum CPUs was done through the BootP Lite utility. The switch to Unity versions of the CPU was driven by the need for more memory with the phasing out of Concept software. The M340 offers a different experience, especially praised for small to medium projects despite some awkwardness with its Ethernet/IP capabilities.
I am actively seeking out data regarding key details such as Make, Model, Serial Number, Firmware Versions, and Ethernet Configuration. This information is typically stored in the Modbus registers of various devices, simplifying the retrieval process. It appears that we only need to cater to Unity versions for now. If there is a more suitable protocol for gathering this data, I am open to exploring other options.
It seems unlikely that the information is stored within the Modbus registers on that CPU. It appears that Modbus is the only protocol compatible with that particular CPU.
Certainly! Modbus register mapping for any Schneider Electric Momentum Unity PLC is generally found in the respective product's programming guide. You may find this on Schneider Electric's official website under the product support section. However, the specific register mapping usually depends on how the PLC has been programmed. If you have the PLC programming software, it may be beneficial to look into the project file to glean some specific info. Hope this helps!
Hey there! I remember having a similar issue with a Schneider Electric PLC model a while back. There's a document titled "Modbus Read/Write Configuration" which should have the register mapping details for your Momentum Unity M1E PLC. It can typically be found on the Schneider Electric's website under their technical publications section. However, if you still have problems finding it, just let me know. I might be able to dig up the one I used from my old files.
Sure, I can help with that. You can get the Modbus/TCP register mapping for Schneider Electric Momentum Unity M1E PLC from the Schneider Electric website -- there's a specific section on it and it's really helpful. However, keep in mind that the table representation may be a little difficult to comprehend at first glance due to its detail. Also, consider investing in a Modbus protocol analyzer if you'll be working on this extensively; it would significantly simplify your work.
Have you checked out the official Schneider Electric documentation or support forums? They usually have the register mapping details for older models like the Momentum series. Additionally, the Modbus protocol mapping might also be available in the Unity Pro software if you have access to it. If not, reaching out directly to Schneider's tech support can often yield quicker results!
