To begin, the engineer must define the hardware configuration in the device view of TIA Portal. While S7-PLCSIM allows for the simulation of the CPU, it offers limited support for technology objects and specific hardware modules (e.g., specialized communication processors). The engineer must ensure that the "Supported by PLCSIM" filter is active or verify compatibility in the module properties.
For a professional post targeting engineers looking to optimize their experience, focus on its ability to test logic without physical hardware and its specific enhancements over previous versions. Drafting Your Post: SIMATIC S7-PLCSIM V15.1 simatic s7plcsim v151 download better
Do not use "Custom" unless you are an expert. Make sure "Enable simulation of interconnections" is checked. To begin, the engineer must define the hardware

PLCSIM V15.1 allows you to save the complete CPU state (including timers, DBs, and output states). This is a for testing recovery scenarios.
Unlike legacy standalone simulators (such as S7-PLCSIM V5.4 for Step 7 Classic), S7-PLCSIM V15.1 operates as a tightly integrated plug-in within the TIA Portal environment. This integration ensures that the simulation instance shares the same tag database and hardware configuration as the engineering project, eliminating discrepancies between the configured hardware and the simulated logic.
