I am currently working on integrating an outdated Schenider Electric Momentum Unity M1E (171 CBU 980 91) and am struggling to locate the Modbus/TCP register map. Can anyone provide guidance on where to find this essential information for seamless integration?
The 'register map' for a Momentum CPU, like any Modbus CPU, is determined by the program in the PLC. The data is stored in registers assigned during programming. If the original programmer is unavailable and the 'source code' file is missing, it could pose a serious issue. While older Momentum CPUs may have had limited memory for program code download and upload, modern PLCs have improved in this aspect. If you have an HMI in the system, you may be able to deduce some register locations from it. Do you have a specific need for a 'register map'? Momentum gained popularity for being one of the first CPUs under $1000 to include an Ethernet port with an open protocol. Setting Ethernet IP addresses for the CPUs was done using the BootP Lite utility. The Unity versions of the Momentum CPU were introduced to accommodate the new programming software as Concept software became obsolete. The M340, on the other hand, is favored for small to medium-sized projects despite some awkwardness in its Ethernet/IP options.
I am actively seeking data on various details such as Make, Model, Serial Number, Firmware Versions, and Ethernet Configuration from devices. The Modbus registers within the devices often store this information, making it easily retrievable. I believe we only need to focus on supporting Unity versions. If there is a more suitable protocol for this purpose, I am open to utilizing it.
I am skeptical that the information can be found in the Modbus registers of that specific CPU. Furthermore, I believe that Modbus is the sole protocol compatible with this particular CPU.
You're right, the documentation for older Schneider Electric devices can be a challenge to find. Have you tried Schneider Electric's official website yet? They have a vast resource library, although unfortunately, it isn't the most organized. For an outdated device such as the M1E, your best bet could be contacting their support directly. They can likely provide you the Modbus/TCP register map or guide you toward any old archives available. Additionally, you might find help in the Modbus community itself or other engineering forums frequented by automation professionals. They often have wealth of knowledge on these older units.
