SimSync Engine Configuration Parameters

Parameter Name

Description

Default Value

Directory path for the initial condition (IC) files

Determines the directory where simulation IC files are stored. When no path is specified, the default snapshot storage location is used. The default snapshot location is: <root install> \ Simulations \ <simulationame>

(for example, C:\SIMSCI\DSS6x\Simulations\MySimulation)

Blank

Directory path for the backtrack files

Determines the directory where simulation backtrack files are stored. When no path is specified, the default backtrack storage location is used. The default backtrack location is one directory above the simulation directory: <root install> \ Simulations \

(for example, C:\SIMSCI\DSS6x\Simulations\)

Blank

Simulation time step

Determines the time increment used by the SimExecutive to run the engine. Data send/receive from other engines occurs at this interval. The simulation freezes, runs, saves, or restores a snapshot at this interval.

The default value is larger than the default value found with the SCP Engine or other Dynsim engines. This is because the SimExecutive does not need to communicate with the SimSync Engine as frequently as those other engines.

See SimSyncEngine Time Slice Behavior section below for more details.

1

Resume using system time after closing SimSyncEngine

Determines whether applications controlled by the SimSyncEngine should

(Value 1) resume using the system time (rather than skewed simulation time) after SimSyncEngine is shutdown.

(Value 0) behave as if they are in a freeze state after SimSyncEngine is shut down.

1

Number of time steps per second (resolution)

The actual HMI application may typically run at a finer time step. InTouch time-based scripts often run as fast as 100 milliseconds per time step. The engine runs the specified number of times per second. If the simulation time step and the number of time steps (slices) per second do not match, the application adjusts the value automatically and warns the user.

Integer values only.

See SimSync Engine Time Slice Behavior for more details.
