SIEMENS SIMATIC S7-PLCSIM – Software for SIMATIC Controllers

PLCSIM Advanced allows comprehensive simulation of functions during configuration and engineering with STEP 7 (TIA Portal) without the need of physically connection to the S7-1500 / ET 200SP Hardware

It supports generating virtual controllers for simulating S7-1500 and ET 200SP  Controllers to test their function.

The realistic testing procedures of the STEP 7 TIA Portal option allow early fault detection as well as fast validation of functions.

It is also possible to train operator staff  as you can connect an HMI device or an HMI simulation to the virtual controller.

  • For functional testing of the generated SIMATIC S7 user blocks on the PG/PC, independent of the availability of the target hardware
  • To transfer detection and elimination of program faults to an early phase of program development
  • Permits accelerated, cost-reduced initial commissioning, and an increase in program quality
  • Can be used for LAD, FBD, STL, S7-GRAPH, S7-HiGraph, S7-SCL, CFC, S7-PDIAG, WinCC (local installation)


Mode of operation

S7-PLCSIM simulates a SIMATIC S7-CPU with the associated process images. The program to be tested is loaded into the simulated S7-CPU and runs on it in exactly the same way as on real hardware. S7-PLCSIM also supports an interface that allows the exchange of process values between S7-PLCSIM and other Windows applications. Communication is based on the included PROSIM interface that can be programmed per COM object.

Design and functions

S7-PLCSIM executes the user program just like a real controller (special functions such as F technology only conditionally). During program execution, different process values can be monitored and changed via a simple user interface (e.g. switching inputs/outputs on or off).

Link-up with an external process simulation

The S7-ProSim interface is used for linking up to external process simulation systems. Dynamic access to process values is possible via this interface. The PROSIM Interface is using the COM Object and is programmable for example with the Microsoft Visual Studio C++ V6.0 and the Microsoft Visual C++ .NET.
