We used to despise web scraping and tried to dump data from an industrial system by listening to raw Modbus RS-485 traffic. Turned out that there was no way to get the register maps from the vendor nor the firmware. We ended up writing a scraper for the main unit. Once they have been installed and configured, they're likely not going to be updated unless absolutely necessary (such as when adding new, unsupported controllers to the bus). |
