Product Description

A SIEMENS Simulation Output Module (sometimes called a Test or Emulation Module) is a specialized component used primarily for testing, validation, and commissioning of control programs and automation systems without needing to connect to the actual field actuators and machinery.

Unlike standard output modules which deliver signals to the physical process, a Simulation Output Module allows the user to monitor and visualize the state of the controller’s digital and analog output commands directly on the module itself (often via built-in LEDs or numerical displays). It provides an internal loopback or monitoring point for the output signal, preventing the control signal from being sent to the real world while still allowing the CPU to execute its logic fully. This is essential for Software-in-the-Loop (SIL) or Hardware-in-the-Loop (HIL) testing environments.

Product Parameters

Product Advantages

• Safe Commissioning: Allows for comprehensive pre-commissioning and dry-run testing of the control logic and sequences without the risk of accidentally moving dangerous machinery or damaging expensive equipment.

• Rapid Program Validation: Engineers can quickly observe the response of the control program (PLC code) to various simulated conditions and debug the logic efficiently.

• Troubleshooting Isolation: Helps isolate software faults from hardware faults. If the LEDs/displays react correctly, the logic is sound, pointing any issues toward external wiring or field devices.

• Training and Education: Provides an ideal platform for operator and maintenance training by allowing them to observe the system’s reaction to control commands in a safe, controlled environment.

• Portability and Bench Testing: Enables the creation of portable test benches where the control program can be tested remotely from the actual installation site.

Important Considerations

• Physical Disconnection: Ensure that the Simulation Output Module is never connected to real actuators, as it is designed for monitoring only and lacks the necessary power circuits to drive industrial loads.

• Addressing: The module must be correctly addressed and configured within the engineering software (TIA Portal) to correspond to the outputs it is intended to simulate.

• Module Selection: Select a simulation module that perfectly matches the channel count and type (Digital/Analog) of the standard output module it is replacing for the test.

• Diagnostic Limitations: While the module verifies the CPU’s logic, it cannot simulate or diagnose faults related to external field wiring or the actuator itself (e.g., a broken solenoid wire).

Product Applications

Simulation Output Modules are specialized tools used primarily during the development and testing phases of automation projects.

• Factory Acceptance Testing (FAT): Used extensively during the FAT phase to prove the controller program meets all specifications before shipment to the site.

• Site Acceptance Testing (SAT) – Dry Run: Used on-site before physical wiring to ensure the program is installed correctly and communicating with the main controller.

• Control System Development: A core tool for software developers to verify control algorithms, interlocking sequences, and state machine transitions in a risk-free environment.

• Software Version Upgrades: Testing new software releases or patches on existing systems to ensure no unintended changes in the output control signals occur.

• Complex Sequence Validation: Verifying intricate sequences and safety interlocks that involve multiple outputs and time delays.
