Appendix G: Operation of Simulation Software

The operation of this training simulation is kept as simple as possible. An operator or student may call up displays, change variables or toggle trend pens. Every other operation totally depends on the configuration of this software package. Therefore, the basic operation is explained first, followed by some operator advice which relates to the training applications delivered.

G.1 Starting the Program from DOS

Before you actually start the software, make sure the current directory is the directory where the software has been installed. If this is not the case, use the DOS command CD to change to the directory to location of the software.

C > CD C:/CTL_APPL

Then, type MENU , and a menu showing available exercises will appear. Then, use the cursor keys to move the cursor on screen to the appropriate application. Press Enter, and the exercise pointed to, will come up.

G.2 Starting a Customized Application from the DOS Prompt

This is only necessary when starting a custom-made application that is not found in the menu. For each training application there exists a configuration file with the extension PCF (process configuration file). The configuration file defines displays, operator access and calculations for control and simulation. The program CONTROL.EXE reads the configuration file filename.PCF and executes the process as configured.

Start program CONTROL.EXE from the DOS prompt:

DOS prompt > CONTROL filename

An example of starting a customized application is the file LEVEL.PCF:

C > CONTROL LEVEL

After the program name CONTROL, the filename of...
