Virtual Hardware Box

This complete package contains 25 practical SCL function blocks that cover key automation tasks – from safety and emergency stop logic to monitoring (current, voltage, frequency, level, temperature, phases) and control and counting functions (pulse, operating hours, flashing, and relay logic). Ideal for beginners, designers, and developers who need robust, realistic control blocks to implement projects faster or systematically build control knowledge.

Note: All modules are designed exclusively as a learning, testing, and development basis and are not automatically released for live, productive operation. Before use in real machines or systems, the modules must be tested, adapted, integrated, and validated into the target environment by qualified specialists.

The package includes the following functional modules:

1. Emergency stop switch
2. Level switch
3. Safety switch
4. Pulse counter
5. Operating hours counter
6. Speed monitoring
7. Phase monitor
8. Frequency relay
9. Level relay
10. Voltage relay
11. Temperature relay
12. current relay
13. Motor protection relay
14. residual current circuit breaker
15. Circuit breaker
16. Limit monitor
17. limit switch
18. Button (normally closed contact)
19. Button (impulse switch)
20. Flasher relay
21. Bistable relay
22. Time relay OFF delayed
23. Time relay ON delayed
24. Schütz
25. Relay (normally open contact)

• Runs on Siemens S7-1200 and S7-1500 controllers
• Developed for TIA Portal version V13 or higher; TIA Portal V16 or newer is recommended for full use of HMI, simulation, and diagnostic tools (e.g., PLCSIM)
• Modular integration into existing control architectures possible
• Simulation and preparation without real hardware through many virtual inputs and test modes

You will receive:

• One or more SCL files with all 25 implemented function blocks
• Complete declaration of all inputs and outputs as well as internal states
• Commented logic (German) for quick adaptation and integration
• Quick guide for integration into a TIA project

The download link will be available immediately after purchase.

I support you with:

• Adapting the logic to your system requirements
• Integration into higher-level process or safety controls
• Interpretation and extension of diagnostic and feedback signals
• Combination of several building blocks for complex processes

Contact is possible via shop message or email. Individual extensions and customization are available as options.
