The ProTRAX Run Time Executive (RTEXEC) serves multiple functions, including coordinating the simulator, controlling training sessions, running the models, and providing local control operations.
RTEXEC initializes the simulator for training so that the instructor can concentrate on the activities of the trainee rather than the operation of the simulator. One mouse click on a desktop icon starts the simulator. The initialization tasks are automatically performed, and everything the instructor needs to begin training is displayed on the desktop.
This includes the Button Overlay Bar ("BOB"), shown to the right, which provides quick access to all of the standard commonly-used functions, as well as those customized for and/or by the instructor. The pull-down menu on BOB allows the instructor to instantly change to different views of the bar, each of which displays a different set of buttons.
BOB greatly simplifies use of the simulator as a training tool, and saves time by providing instant access to features that have been optimized for the instructor's specific needs. In addition to displaying BOB on the Instructor or Operator Stations, you may choose to use a portable handheld device from which you can remotely control the simulator through BOB's functions.
The Run Time Executive also includes the Operator Proficiency function, which launches and manages simulator training sessions. Used by both instructors and trainees, the Proficiency program monitors, displays, and archives results of each training session. The training-related functions of the Executive include the following:
Initializes the simulator for training
Runs simulation models
Tracks and records trainee proficiency
Displays local operation screens (LOS)
Displays button overlay bar (BOB)
Displays and runs Teaching Assistant training modules
Displays DCS operator graphics
Provides tools to build and modify training scenarios
Invokes malfunctions
Records data
The ProTRAX Run Time Executive features:
Selectable pre-programmed training scenarios
Unlimited on-line programmable malfunctions
Dynamic plant schematics at runtime
Operator action tracking
Freeze/Run toggle
Snapshot/Backtrack
On-line parameter changes (either manual, with saved program files, or event-driven)
On-line trending of unlimited variables simultaneously
Post transient plotting
Unattended running of prescribed dynamic simulation transients including multiple runs, plot outputs, and parametric studies
Trainee Proficiency Program with quantitative performance scoring for trainee
Convenient interface to external programs
"Drag and drop" capabilities designed for ease of use
Export of logged data to third party software such as Microsoft Excel
As demonstrated in the Instructor's Screen above, the Run Time Executive allows you to access the schematics during runtime and use them to view dynamic data for a specific component or flowstream, or control the simulation by changing parameters on-the-fly.
During runtime, clicking on any module component on the schematic will open a window with four options, allowing the user to:
View values of variables associated with the module itself, such as valve position, drum level, pump speed, etc.
View all current parameter values for the selected component, or change any of these parameters at runtime. This is a typical means of tuning control system parameters.
Invoke a malfunction for the selected component.
Define a new malfunction for the selected component.
In addition, variable lines and flowstreams dynamically change color to visually identify their state or value. By clicking on a flowstream, a window opens that shows the pressure, enthalpy, density, temperature, flowrate, and composition (as applicable) of the flowstream at that particular point. Any number of these windows may be opened and positioned on the screen as desired.
