Introduction
1.1
Overview
With the SIMATIC S7-PLCSIM Advanced virtual controllers for the simulation of a S7-1500 or ET 200SP CPU are created and used for the comprehensive simulation of functions. Therefore no real controllers are required to test a STEP 7 program.
The virtual controllers can also be tested and validated in the context of a system or machine. The user interface (API) is used to connect the virtual controller to a plant/system or machine simulation (co-simulation).

PLCSIM Advanced With S7-PLCSIM Advanced as independent simulation system, the created user program can be simulated and tested on a virtual controller. The Runtime API of S7-PLCSIM Advanced (details see chapter 3.1.6) provides user interfaces for access to the simulation runtime. These user interfaces offer the following options via a program (for example, C# program): Creation of a runtime instance of a virtual controller. Changing the mode of the virtual controller. Exchanging I/O data with a co-simulation. In this application example a local communication via the PLCSIM Softbus is used. However, with S7-PLCSIM Advanced a distributed communication via a virtual Ethernet adapter is also possible.

1 Introduction 1.2 Mode of Operation
STEP 7 (TIA Portal) program
A STEP 7 program created in STEP 7 V14 (details see chapter 3.2.1) controls a conveyor system. For a comprehensive function test, the STEP 7 program is loaded via S7-PLCSIM Advanced into a virtual S7-1500 controller. This controller interacts via the API with a co-simulation (system simulation), in order to validate the STEP 7 program in the context of the system.
The material handling system to be controlled consists of two transport belts and two robot arms. The following input and output tags are defined so that the controller communicates with the material handling system:

The according control signal is activated based on the active sensor signals. For transport belt 1 (moveBeltActive) a monitoring time of 5 s is configured. If the package does not reach the target position within this time, an error for a fallen down package is shown ("Package down"). You can then restart the system or acknowledge the error when you put the package back on the transport belt 1.

1 Introduction 1.2 Mode of Operation
The visualization of the system is simulated with WinCC Runtime. The system can be monitored and controlled in WinCC Runtime via an HMI screen:
Restart (restartActive) Acknowledge error (acknowledgeActive)
C# program In the external application (C# program) the following is programmed: Functions of the user interface (Runtime API) in order to interact with the virtual controller of S7-PLCSIM Advanced. System simulation of the conveyor system (co-simulation). The co-simulation reacts to the control signals (outputs) of the virtual controller and simulates all required sensor signals (inputs) for the simulation of the sequential control (details chapter 3.2.2). For the exchange of the I/O data the Runtime API writes and reads from the memory area that is synchronized on the cycle control point with the internal process image of the virtual S7-1500 controller.

With the co-simulation you can simulate or remove errors, for example, drop a package or place a dropped package back on transport belt 1.
Note
The machines of the conveyor system are simulated in a non-realistic way in the co-simulation. The movements are only simulated by a time constant.

Distributed communication
Distributed communication means that S7-PLCSIM Advanced instances can be connected via the PLCSIM Virtual Switch to a network. Thus, instances can also communicate across all computers with other devices.
A communication with real or simulated CPUs or HMIs is possible.
Virtual time behavior
The virtual controller internally uses two types of clocks for the simulation:
Virtual clock
Forms the basis for the application program and is used by components that are dependent on control processes (for example, cyclic OBs, cycle monitoring, minimal cycle time, system time and time calculations).
The virtual clock can be accelerated or slowed down.
Real clock
Cannot be accelerated or slowed down and is used by components that are not dependent on control processes, for example, the communication with STEP 7.
With PLCSIM Advanced you can slow down or accelerate the virtual clock for test purposes.
Note
If you receive a cycle time error during the simulation of a program, slow down the virtual clock by selecting a scaling factor smaller 1.

Co-simulation program
Overview
The co-simulation program is programmed in the Visual Studio project in the method "CoSimProgramm()" of the class "Cosimulation.cs".
The program is programmed in a step sequence (switch-case). For the simulation of a sensor and the operation of a machine, a timer is started in the respective step, after its lapse the "nextStep" tag is set.
The following figure shows the program sequence of the co-simulation.
Figure 3-6: Co-simulation program sequence
Siemens AG 2016 All rights reserved
Error simulation
By setting the "error" tag, it is simulated that a package falls down from transport belt 1.
When the "error" tag is set, the program interrupts the regular sequence in step 3 and jumps to step 99 (error simulation).
The error simulation is ended, when the package is replaced onto transport belt 1 ("packageOk") and the error is acknowledged in the controller (acknowledgeActive) or the system is restarted (restartActive).
Note
Additional description of the co-simulation program can be found in the comments in the program code.
