Product Description

The functionality of a Simulation Output Module is fulfilled by a software interface that allows a real or simulated PLC program to execute its output commands without physically engaging actual actuators or machinery. This module provides a “digital twin” or virtual representation of the physical outputs.

Its purpose is to receive the output data (Digital or Analog values) generated by the CPU’s logic and pass it to a simulation model (e.g., a kinematic model of a robot, a fluid dynamics model, or a 3D machine model). This allows control programs to be tested and debugged in a safe, non-physical environment.

Product Parameters

Parameters are primarily software-based, defining the interface’s capability:

• Data Exchange Rate: The speed and synchronization frequency at which the simulated output data is exchanged between the PLC and the external simulation environment (e.g., milliseconds).
• Interface Protocol: The communication method used to transfer output data (e.g., dedicated API, TCP/IP, or industry-standard co-simulation protocols like Functional Mock-up Interface – FMI).
• Data Format: Support for various output data types, including binary (Digital), integer/floating point (Analog), and complex Motion Control variables.
• Compatibility: The range of SIEMENS CPUs and external simulation software packages supported by the interface.
• Capacity: The maximum number of simulated output points that the interface can handle simultaneously.

Product Advantages

1. Risk-Free Debugging: Enables thorough testing of complex control logic and sequences without the risk of damaging expensive machinery or injuring personnel.
2. Time and Cost Savings: Reduces physical commissioning time on the shop floor by shifting a significant portion of testing to the office environment.
3. Parallel Development: Allows PLC programming and mechanical/electrical design to proceed simultaneously, as the control program can be tested before the physical hardware is even built.
4. Early Error Detection: Facilitates the identification and correction of design flaws, sequencing errors, and timing issues much earlier in the project lifecycle.
5. Operator Training: Provides a realistic environment for training machine operators and maintenance personnel on new equipment or revised control sequences.

Precautions

• Simulation Model Accuracy: The validity of the testing depends entirely on the accuracy and fidelity of the external simulation model representing the real-world output behavior.
• Resource Demand: Running a simulation module concurrently with an actual or virtual PLC can be computationally intensive, requiring robust engineering workstation hardware.
• Synchronization: Ensure precise synchronization between the PLC cycle time and the simulation model’s update rate to achieve realistic dynamic behavior.
• Scope Limitation: A simulated output module cannot perfectly replicate all real-world electrical or mechanical non-linearities, and final testing must still occur on the physical machine.

Product Applications

The Simulation Output Module functionality is critical for modern engineering practices:

• Virtual Commissioning: Testing and validating the entire automation project logic against a 3D kinematic model of the machine or robot cell before power-up.
• Hardware-in-the-Loop (HIL) Testing: Connecting a real physical PLC to a simulated environment to verify the control program with actual hardware interaction.
• Robotics Simulation: Validating robot path planning, collision detection, and synchronization with other machine components.
• Process Model Validation: Connecting PLC outputs to detailed process models (e.g., chemical reactors, piping systems) to test control strategies under various load conditions.
• Pre-acceptance Testing (FAT): Performing a virtual Factory Acceptance Test with the customer to gain early sign-off on the control program.
