Hello, I can troubleshoot and resolve the communication failures on your M Bus network and datalogger. My plan is to start by auditing the datalogger serial communication settings to verify baud rate framing matching the standard 2400 baud 8E1 configuration. I can check the physical M Bus line voltage to ensure the master converter supplies proper space state voltage around 30 to 36 volts DC and check for short circuits. I can run primary and secondary address scanning from the datalogger interface using meter serial numbers to resolve address collisions. I can also analyze raw M Bus frame logs like SND_NKE initialization and REQ_UD2 data requests to confirm meter response telegrams and fix payload parsing errors in your datalogger. 1) What is the exact brand and model of your M Bus datalogger or master converter? 2) Are the energy meters configured using primary addresses or secondary addresses like 8 digit serial numbers? 3) Can we access the datalogger diagnostic logs or terminal interface during a remote session? Thanks, Bharat

HI, KINDLY READ THROUGH MY PROPOSAL I will diagnose and resolve the communication issues on your M-Bus network so that all meters report correct readings instead of 0 kWh. MY APPROACH ✅ Check physical layer (wiring, polarity, bus voltage, termination and cable length) ✅ Verify primary/secondary addressing, baud rate and master configuration in the datalogger ✅ Test individual meters and isolate faults (short circuits, missing power, incorrect addresses or failed devices) DELIVERABLES - Root-cause diagnosis - Corrected configuration and working meter readings - Short report of the changes made QUESTIONS 1. How many meters are on the bus and what is the approximate cable length? 2. Can you share the datalogger model and any error messages or screenshots? Ready to start immediately.

Hi there! It looks like the datalogger is accessible, but the M-Bus meters are not communicating correctly and are returning 0 kWh readings. I have experience with network troubleshooting, communication protocols, device connectivity, and diagnosing issues between field devices and data collection systems. I can investigate the M-Bus setup and identify whether the issue is with wiring, addressing, configuration, communication, or the meters themselves. My approach will start by checking the datalogger configuration and M-Bus communication status. I will verify meter addresses, baud rate and protocol settings, then review network wiring, termination, power levels, and communication logs. After identifying the root cause, I will apply the required configuration changes and verify that actual meter readings are being received correctly. check our work https://www.freelancer.com/u/ayesha86664 Can you share the datalogger model, M-Bus setup details, and any available communication logs? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

I can help troubleshoot the M-Bus communication issue end to end. Since the datalogger is online but all meters report not reading / 0 kWh, I would approach this systematically: verify the physical bus layer, confirm M-Bus master polling settings, check primary/secondary addressing, validate baud rate and telegram format, then inspect meter response frames and error patterns. The key is to isolate whether the issue is wiring/power, address mapping, or a configuration mismatch between the datalogger and the meters. I will review the logger’s meter table, communication logs, and any read attempts to identify where the chain breaks. From there, I can recommend precise changes and confirm recovery with test reads and consistency checks across the network. I focus on practical diagnostics, fast root-cause identification, and a clear resolution path so the meters return valid readings reliably.

@bhaskark96

Hello, I can help diagnose and resolve the communication issues on your M-Bus network. Since the datalogger is accessible but all meters are reporting 0 kWh or not reading, the problem is likely related to M-Bus communication, meter addressing, wiring integrity, bus voltage, configuration, or polling settings. My approach will include reviewing the network topology, verifying M-Bus communication parameters, checking meter addresses and scan results, analyzing datalogger logs, and identifying any communication faults between the master and connected meters. I will then perform targeted troubleshooting to restore reliable meter readings and validate data collection. I have experience with network diagnostics, communication protocols, and troubleshooting field devices, and I can assist remotely by reviewing configuration files, logs, and screenshots or guide on-site testing if required. I look forward to helping you get the system fully operational. Thank you.

Hi there! Quick question - have you checked whether your M-bus repeaters or power supplies are functioning properly, or is this purely a communication/configuration issue on the datalogger side? Regardless, this is definitely something that I feel confident delivering on, given my past experience. I would love to discuss your project further! Looking forward hearing from you. kind regards, Corné

@JunaidBadroodien

I understand you're facing communication challenges within your M-bus network, specifically with your datalogger displaying all meters as returning 0 kWh readings. This can be frustrating, especially when accurate data is critical for your operations. My approach begins with a thorough assessment of your M-bus system, focusing on the communication pathways between the datalogger and each meter. I'll perform diagnostics to identify potential issues, such as faulty wiring, configuration errors, or protocol mismatches. By systematically isolating each component, I can pinpoint the root cause of the problem. Once the issue is identified, I'll implement targeted solutions, which may include recalibrating devices, updating firmware, or adjusting network settings to ensure seamless communication. My goal is to not only restore functionality but also enhance the reliability of your entire system. By addressing these issues with precision, you'll gain accurate readings and improved operational efficiency, allowing you to make informed decisions based on reliable data. Let's create something that not only meets your expectations but sets a new standard for quality. Regards Junaid
