SIMIT V10.2 Features, Simulation Architecture, and Demo Mode Constraints

SIMIT V10.2 Features, Simulation Architecture, and Demo Mode Constraints

Siemens SIMIT V10.2 delivers advanced virtual commissioning and plant simulation capabilities for SIMATIC PCS 7 V9.0 SP3 and TIA Portal V16. Key architectural enhancements include SIMIT Virtual Controller V10.2 supporting CPU 410-5H Firmware V8.2, expanded OPC UA client/server couplings, and enhanced Component Type Editor (CTE) modeling. Without a valid license key installed in Automation License Manager, SIMIT V10.2 operates strictly in Demo Mode. Demo Mode imposes critical operational constraints: simulation runtime is limited to 45 minutes, saving project modifications is disabled, coupling communication is restricted, and component libraries cannot be exported. For production virtual commissioning, validate required SIMIT licensing tiers with an authorized Siemens distributor or the Siemens Industry Mall.

Executive Summary

Virtual commissioning has become a mandatory phase in modern process automation engineering, allowing control logic, safety interlocks, and operator graphics to be tested before hardware deployment. Siemens SIMIT Simulation Platform V10.2 introduces significant functional improvements, particularly for large-scale PCS 7 and TIA Portal architectures. However, engineers evaluating or downloading the software must navigate the functional boundaries between licensed runtime editions and the default Demo Mode. This article provides a comprehensive technical overview of SIMIT V10.2 architecture, new features, licensing packages, and specific Demo Mode operational limits.

Architecture and Fundamental Mechanics

The simulation architecture of SIMIT V10.2 is structured into three foundational tiers:
1. Core Simulation Engine and Couplings:
- SIMIT executes real-time behavioral models of process equipment (valves, pumps, heat exchangers, chemical kinetics).
- Couplings interface the simulation engine with controllers. SIMIT V10.2 supports SIMIT Virtual Controller (VC), S7-PLCSIM, S7-PLCSIM Advanced V3.0, OPC DA/UA, PRODAVE, and shared memory couplings.
2. SIMIT Virtual Controller (VC) V10.2:
- Emulates SIMATIC S7-400 and AS 410-5H controller firmware without physical PLC hardware.
- Supports CPU 410-5H Firmware V8.2 and S7-1500 firmware up to V2.8.
- Enables clock-synchronized execution and exact real-time or accelerated/decelerated time factor execution.
3. Licensing Model and Automation License Manager Integration:
- SIMIT software packages include SIMIT Standard, SIMIT Professional, and SIMIT Ultimate.
- Virtual Controllers require dedicated SIMIT Virtual Controller runtime licenses (sized in increments: 1, 5, or more VC instances).
4. Demo Mode Operational Constraints:
- When launched without an active license key in ALM, SIMIT automatically enters 'Demo Mode'.
- Operational Limits in Demo Mode:
a. Runtime Limit: The simulation engine terminates execution after exactly 45 minutes.
b. Save Disabled: The 'File -> Save' and project backup functions are blocked; modified charts cannot be persisted.
c. Coupling Restrictions: Only single-instance couplings are permitted; multiple concurrent Virtual Controllers are blocked.
d. Component Type Editor: Custom behavioral block creation is restricted to read-only evaluation.

Step-by-Step Implementation Procedure

  1. Download and Verify SIMIT V10.2 Installation Media:
    a. Download the official SIMIT V10.2 installation package from Siemens Industry Online Support (SIOS Entry ID 109779320).
    b. Verify file hash integrity and extract the installation archive.
    c. Run Setup.exe on a supported 64-bit operating system (Windows 10 Enterprise LTSC or Windows Server 2016/2019).

  2. Configure Automation License Manager (ALM):
    a. Open Automation License Manager.
    b. Transfer required license keys: SIMIT V10.2 Engineering License (Standard/Professional/Ultimate) and SIMIT Virtual Controller licenses.
    c. If evaluating without licenses, launch SIMIT directly to run in Demo Mode.

  3. Establish Controller Coupling:
    a. Open SIMIT V10.2 and create a new simulation project.
    b. In the Project Navigation tree, double-click 'Couplings -> New coupling'.
    c. Select 'Virtual Controller' for PCS 7 emulation or 'PLCSIM Advanced' for S7-1500.
    d. Configure station parameters matching the PCS 7 AS hardware configuration.

  4. Import Technological Engineering Data:
    a. For PCS 7 projects, use the 'Import -> Plant Automation Accelerator (PAA) / PCS 7' wizard.
    b. Import signal lists and chart definitions to automatically generate I/O coupling variables and basic drive/valve simulation components.

  5. Execute Simulation and Monitor Operational States:
    a. Click the yellow 'Play' button in the toolbar to start simulation.
    b. If running in Demo Mode, monitor the status bar runtime counter indicating the remaining time before the 45-minute cutoff.
    c. In licensed environments, verify continuous real-time execution (Time factor = 1.00).

Verification

  1. In SIMIT V10.2 title bar: confirm project title does not display '[Demo Mode]' when valid ALM licenses are active.
  2. In Automation License Manager: verify SIMIT licenses display 'In use' status during active simulation runs.
  3. Execute simulation for over 60 minutes: verify simulation continues running without interruption, confirming licensed operation.

Limitations and Operational Precautions

Demo Mode cannot be used for engineering development or factory acceptance testing (FAT) because saving is disabled and execution terminates after 45 minutes. Virtual Controllers require separate runtime capacity licenses.

Engineer FAQ

What are the time limits of SIMIT V10.2 Demo Mode?

Demo Mode terminates simulation execution automatically after 45 minutes of continuous runtime.

Can I save simulation projects created in SIMIT Demo Mode?

No. The project save and export functions are completely disabled in Demo Mode.

What controllers does SIMIT Virtual Controller V10.2 support?

It supports S7-300, S7-400, S7-410 (including CPU 410-5H Firmware V8.2), and S7-1500 controllers.

Does SIMIT V10.2 support OPC UA communication?

Yes. SIMIT V10.2 includes robust OPC UA client and server couplings for co-simulation with external digital twin tools.

Are SIMIT Virtual Controller licenses included with SIMIT Professional?

No. SIMIT Virtual Controller (VC) runtime instances require separate capacity licenses purchased in unit packs.
