@preetha.kannaiyan Can you share more information about the issue you are running into? The Modbus analyzer should be pre-installed and included with the Logic 1.x software, and can be added to your capture by following the instructions below (under the Logic 1.x section).

If you are adding it to your capture, and data is still not decoding, it’s possible that your specific data might be incompatible with our Modbus analyzer. I’d be happy to look into that for you if you can provide your .logicdata capture file. Instructions below:
