• If you downloaded the license via the DRM portal (Method 1), the license file usually needs to be transferred to your computer via the Automation License Manager after the installation is complete.

• No 64-bit support: Absolute. You cannot run this on native Windows 10/11 64-bit.
• Network simulation is limited: You cannot simulate PN/IO (Profinet) devices; only DP (Profibus) and MPI.
• Time bomb: The internal clock of PLCSIM runs fast (approx. 1.2x real-time). Do not use it for time-critical motion control simulation.
• Microsoft Deprecation: Windows 7 is EOL. Running PLCSIM on a Windows 7 PC connected to a plant network is a cybersecurity risk.
