This manual is a practical training workbook, not a substitute for the installed product manual or the site's approved engineering procedure. Record the exact software, firmware, license and hardware before following a step because menus and supported functions can vary by release.
Tested-version planning scope: Confirm TIA Portal V18 or V19 SCL, the target controller firmware, data-access mode and current IEC-style syntax. Enter the exact lab-tested software, firmware and hardware in the record below before course delivery; never assume cross-version compatibility.
Software build, firmware, device catalog, driver, communication interface and license status.
Use an isolated training system. Follow electrical, mechanical, process and cybersecurity controls before energizing or downloading.
Keep the source project, parameter/code export, screenshot/trend, fault test, correction and final pass result.
