Add-on module Fourth Dimension

Note: You must have a license for the add-on module.

This control procedure is deployed in North America.

Depending on the Vissim edition purchased, you are provided with the dialog file D4gui.dll and the program file D4.dll files for the 64-bit version.

Some control procedures expect the supply file to be saved in the same directory that contains the *.inpx file. If a control file is saved to a directory that does not meet the requirements of the control procedure, this can cause the program to crash. The supply files of the control procedures Fixed time/Vissig, VAP and RBC can be saved to any directory Vissim can access. Vissim does not need the supply files to be saved to a specific directory. Should you have any questions regarding supply files, please contact the company that developed the control procedure.

1.  When you define a signal controller, in the Type list, click Fourth Dimension D4.

2.  Select the desired data file.

3.  Make the desired changes:

Element	Description
Data file	ProgDat: Supply file of control logic
Program no.	ProgNo: The signal program which is to be simulated. A change of program is possible if the simulation run is in single-step mode. If the new signal program number is confirmed with OK, the changeover is triggered in the next simulation second.

The control procedure also uses a WTT-file, e.g. D4.wtt.
