S7-PLCSIM Getting Started introduces the basic information of S7-PLCSIM tool software, including S7-PLCSIM introduction, differences with real PLC, installation and use, software compatibility, etc.
This guide introduces Siemens S7-PLCSIM, a Windows‑based simulation tool that lets users test S7 PLC programs without hardware. It explains the software’s basic information, installation steps, and how to activate the simulator within STEP 7.
The document also details the differences between the simulator and a real PLC, lists supported resources such as timers and memory, and provides troubleshooting answers for common questions about priority, communication simulation, and timer behavior. This manual is written in Chinese.
| Timer range | T0‑T2047 |
|---|---|
| Memory size | 131,072 BIT (16 KB) |
| I/O address range | 131,072 BIT (16 KB) |
| Local data area | 32 KB (default) |
| Logical blocks / Data blocks | 2048 FB/FC, 4095 DB |
S7‑PLCSIM’s priority is higher, so all download, upload and monitoring actions target the simulator while it is running.
No, S7‑PLCSIM cannot simulate communication programs such as PTP or Ethernet communication.
