Field notes
The tool list spans common troubleshooting steps, from interpreting Float32, Int32 and UInt16 values in different byte orders to checking RTU/TCP frames and generating requests. The register-map section names six device families, including GoodWe ET/EH inverters and multiple Victron products. PLCBytes says processing stays in the browser; it also cautions that results and maps should be checked against manufacturer documentation.
