Is there a reliable method for extracting modbus data from a GE Multilin 850 correctly? The registers aren't aligning, causing inaccurate values to be displayed. There must be a simpler solution to this issue.
If your communication efforts are yielding positive results, you're on the right track! However, you may need to adjust your data addressing and replace any registers that are long or floats (32 bits). Check out this informative article on common challenges in Modbus communication by Control Solutions.
According to OkiePC, achieving successful communication is a significant accomplishment, but there may still be room for improvement in data addressing and register wording, especially for long or 32-bit floating registers. Here is an informative article from Control Solutions that addresses these common issues in Modbus communication protocols. Thank you for your input. Click to expand for more details.
OkiePC mentioned the importance of successful communications in overcoming common hurdles in data addressing and register swapping. Check out this helpful article on Modbus Tutorial from Control Solutions to brush up on these concepts. It's crucial to address any issues regarding long or float registers (32 bits) to ensure effective communication. Keep up the good work! Hey, Okie, how have you been?
cstep7263 expressed gratitude for the response. It may be helpful to provide examples of the data you sent and received to identify where the issue lies. This is a common Modbus problem, as noted by OkiePC. You've made progress with two-thirds of the solution. I suggest using "middleware" for setup and troubleshooting to eliminate any uncertainties on the receiving end. I recently downloaded Rilheva Modbus Poll FREE Modbus RTU | Rilheva IIoT Platform for this purpose, although I have not used it before. It was a cost-effective choice.
Definitely a common issue with the Multilin 850. Remember that GE's devices often operate with a zero-based index for registers, which might require an offset in some cases. You should cross-verify with the device's Modbus map. Also, the communication settings must match with that of your master device (baud rate, parity, etc.). If all else fails, you might want to consider consulting with GE support or possibly utilizing a more sophisticated Modbus tool, like ModScan.
I've encountered this issue before with a GE Multilin 850. What I found helpful was ensuring the register map was correctly configured and aligned. GE's technical support should have an updated documentation on register mapping for the Multilin 850, you may want to check that out. Also, do consider tools like Modbus Poll or Modscan for debugging. They've helped me to verify the data that I'm pulling and identify any discrepancies.
