WHAT YOU GET

A clear result you can inspect

The BETA ModScan folder contains `read-plan.csv`, `point-map.csv`, test messages, and setup instructions for ModScan32 or ModScan64. It can also include `pymodbus-read-once.py` for one reviewed read when ModScan is unavailable. Native application verification has not been run.

HOW IT RUNS

01 · GUIDESKILL.mdprocess + safety

02 · EXECUTEscripts/run.pybundled local Python

Builds files for the ModScan version you use. The script uses the checked map and matching read plan to create probe or final output. It checks the setup and CSV files. It reports native verification as unavailable unless the files were loaded in the named ModScan application.
