Emulated Industrial Control Execution Rate Scaling

A host system which executes an emulation environment for modelling a logical behavior of an industrial control device may execute a clock management module to scale execution time in the emulation environment to more accurately reflect execution time of the industrial control device. The clock management module may operate to receive repeatable ticks based on a real time clock of the host system. The repeatable ticks may be used to measure execution of a portion of an industrial control program in the emulation environment, which measure may be compared to a reference value for executing the same portion on the industrial control device. The host system may then temporarily stall execution in the emulation environment to match execution on the industrial control device.
