Important Note

Siemens LOGO! Soft Comfort V8.4 is a technical tool for basic automation and programming LOGO! modules. To use it correctly, knowledge of electricity, control logic, inputs/outputs, timers, relays, electrical safety, and the operation of control panels is recommended.

On real equipment, machinery, electrical panels, or industrial processes, any modification must be carried out by trained personnel, as incorrect configuration can affect system operation, operational safety, or connected equipment.

Differences between alternative license and original license

This information is included so that the customer clearly understands what type of license they are acquiring and what functions they can expect depending on the chosen option.

Alternative license: is a non-original, one-time payment license with no monthly or annual subscriptions. It allows functional use of the program to create LOGO! programs, simulate projects, edit control logic, save configurations, document processes, and transfer compatible programs from the installed computer. It does not include official updates, full online services, official Siemens support, downloads from a personal account, corporate licenses, or linkage with the manufacturer's personal or business accounts. Linking accounts, manual updating, or modifying the program may affect activation and require additional technical assistance at a cost.

Original license: is the official manufacturer's option. It includes access to full features according to the contracted plan, official account, online services, available updates, formal licensing, business compatibility, and official support. Its cost is usually higher and it may operate under a professional license, upgrade, subscription, or modality defined by Siemens.

For business, corporate, governmental, industrial, or institutional use, Luctecno recommends original licenses, as they are the appropriate option to comply with best practices, audits, formal support, operational continuity, and higher professional requirements.

Note: These licenses are tied to the computer where they are installed and are not transferable.
