Basics of SIMIT VC
2.11 Synchronization of SIMIT VC with SIMIT SF
the virtual controller coupling. The synchronization of the data exchange and the
synchronization via the Proceed command of SIMIT SF depend on the signal process.
● VCs
The token is divided: One token is made available for each available CPU core. The VCs
now compete for the assignment of the tokens until all have been calculated once via the
Windows operating system functions. The tokens are then combined by the control
process and the next cycle can begin.

Synchronization of SIMIT VC with SIMIT SF
Data exchange between SIMIT SF and SIMIT VC
SIMIT VC and SIMIT SF map two aspects of a technical plant:
● SIMIT VC simulates the automation systems (controllers) including process image of
inputs and outputs (without mapping the field level)
● SIMIT SF simulates the process image of the plant in the form of physical or data values.
Even though field devices can be mapped in their functionality, they are not displayed
directly in the simulation.
SIMIT VC and SIMIT SF exchange this process data through a shared data memory that is
created by SIMIT VC and connecting to SIMIT SF via a coupling when simulation is started.
Configuration of the interface is carried out in the Emulation Manager. The "Virtual
