Difference Between PLCSIM and PLCSIM Advanced? – Siemens PLC

Simulation for your PLC projects and processes before the commissioning would really help you to discover more code bugs and errors before you download the program into your PLC.

Siemens one of the leading companies in the Automation world. Siemens offers two kinds of simulations for its PLC programming software.

They are

  2. PLCSIM Advanced

How are they work and what is the difference between them both? That is, we are going to talk about.

What is S7 – PLCSIM Advanced?

Using PLCSIM Advanced, you can simulate your CPU programs on a virtual PLC controller. You do not need any real controllers for this.

You can configure your CPU with STEP 7 in the TIA Portal, program your application logic, and then load the hardware configuration and the program into the virtual controller.

From there you can run your program logic, observe the effects of simulated inputs and outputs and adapt your programs.

In addition to communicating via Soft bus, PLCSIM Advanced provides a full Ethernet connection and can thus also communicate distributed.

Differences between PLCSIM & PLCSIM Advanced

Runtime Independence

The PLCSIM (V12 or V5.X) cannot run without running of Step-7 software program unlike the PLCSIM Advanced it’s independent.


For PLCSIM (V15 or V5.X) they are communicating just into your PC with a bus called SOFTBUS.

But on the other hand, we will find that PLCSIM Advanced has the ability to communicate with outside devices using TCP/IP protocol and Virtual SIEMENS LAN adaptor and can also make a connection into your PC using SOFTBUS.

Supported CPUs

The PLCSIM Advanced supports S7-1500 and ET-200SP CPUs for the emulating, PLCSIM V12 and Higher support S7-1200, S7-1500, and ET-200SP CPUs and for PLCSIM V5.X can handle S7-300 and S7-400.

Number of Available PLCs That Can be Simulated

PLCSIM V5.X can just simulate one PLC unlike the PLCSIM Advanced can handle up to 16 Instance and PLCSIM V12 and higher can simulate up to 2 PLCs.

OPC UA Sever

One of the best features in PLCSIM Advanced that it can use to emulate an OPC server on 1500 station so you can activate this server and connect it with the SCADA system that supports OPC UA.

Instances Communication

PLCSIM Advanced does not support communication between the simulated PLCs but the PLCSIM V12 instance can communicate with PLCSIM V5.X Via soft bus.

 Advantages of PLCSIM Advanced

  • Improve quality of automation projects by early error detection
  • Avoid costs for hardware in simulation environments
  • Reduced response times
  • Reduce risk for commissioning
  • Earlier training of operator is possible
  • Increase production efficiency by optimizing program components
  • Increase efficiency during replacement of machine components
  • Increase efficiency during expansion of existing plants

NOTE The virtual controller cannot fully simulate a real CPU down to the individual details.

Even if a program is downloaded without errors to the CPU and running successfully, this does not necessarily mean that the virtual controller in the simulation behaves exactly like a real CPU.

Configuration of the Software

Online access Switch to select the communication interface.

TCP/IP communication Selection of network adapter for distributed communication.

Virtual time Slider to adjust the scaling factor.

Start Virtual S7-1500 PLC Opens and closes the input boxes for creating the instance (virtual controller).

  • Name of the instance – Here you enter a unique name for the instance. Enter a minimum of 3, a maximum of 64 characters. If the name is unique in the network, the button “Start” is enabled.
  • IP address
  • Subnet mask
  • Standard gateway – The input boxes are visible when you switch the communication interface to “PLCSIM Virtual Ethernet Adapter”. The IP address is entered automatically.
  • CPU type – Here you select the type of CPU to be simulated.
  • “Start” button – Create with the button and start the instance.
