Abstract
An industrial simulation system exchanges data between a virtualized industrial system and an industrial controller at high frequencies and accuracies without the need for additional network emulation hardware. Rather than timing the sending of emulated device data packets from the simulation to the industrial controller using an operating system clock, the simulation system uses the arrival event of a data packet received from the industrial controller as the clock signal that drives the sending of data packets from the virtual system to the controller. Using the arrival time of data packets from the industrial controller as the clock signal rather than the system clock of the operating system can yield high accuracy, low jitter data exchanges during simulation.
