Automation virtual commissioning : PLCSIM advanced 2.0 with C#

This is is a short demonstration of a co-simulation between Siemens PLCSIM Advanced and C#.
The goal is simple : have the ability to conditionally change inputs.
We’ll do a proof of concept with a small exemple for a safety relay monitored by a feedback.  

Co-simulation : PLCSIM Advanced with C#

1 Configuration

We’ll run the simulator and the editor on two computers :

Simulation configuration

2 Simulator configuration

First let’s start an instance with the following parameters : 

Instance parameters for PLCSIM advanced

Once started, it should be like that :

Simulation running

3 PLC Programming 

3.1 Hardware configuration

Let’s do a simple configuration as follow :

Project hardware configuration

Network configuration : 
– PLC_1 : 192.168.1.1/24
– IO device_1 : 192.168.1.2/24

Note : On the simulator, we have different IP addresses for all the network interfaces : Ethernet adapter, PLCSIM virtual ethernet adapter, PLC and I/Os !

With the following I/Os :

Remote I/Os configuration

Note that you’ll need to activate this option in the project settings :

Support simulation during block compilation option

3.2 Program

Our program will be very simple !

OB1 will toggle a bit every second :

And FB1 will do a safety check between the relay output and the input feedback :

3.3 Compiling and loading 

You should be able to compile and load :

4 Simulation

As soon as you’ll run the program, you should have an error on the feedback monitoring :

5 C# Co-simulation

To solve this issue, we’ll running co-simulation with C#. The script will check the output value (%Q9.0) and set the feedback (%I0.0) accordingly. 
We’ll be using sharpdevelop as IDE.

5.1 Import DLL

Importing the DLL is easy :

Then we write a short program :

And run it :

Once acknowledged, we should not have any issue. 

Using the trace tool, we can confirm that it’s running perfectly fine, updating the input in around 100ms.

  1. Hi,

    it is possible to send me the cods(sps+c#)?

    Do you have more examples?such as encoder simulation via API?
