VISSIM 5.30-05 User Manual

Signal Controllers
Users of the External add-on need to compile the SC DLL files in
accordance with the used VISSIM edition (32 bit or 64 bit).
Users with a license containing this feature can find the API source code
modules and documentation in the API folder of the VISSIM installation.
In the [CONTROLLER (EXT.)] tab, the following parameters have to be set for a
signal control of the External type:
● Program file: User-defined *.DLL
● Dialog DLL file: User-defined *.DLL
● Data file 1: Contains data for the control strategy.
● Data file 2: Contains data for the control strategy.
These data files (1/2) are only required if you do not want to include control
strategy data into the program code of your own *.DLL file.
● WTT files: Value-Type tables contain the SC data types which are to be
displayed in the SC/Detector protocol or in the signal timing plan window
and their display properties.
● Program no.: Select the signal program for simulation. The number of the
signal program can be entered even while the simulation is running.
● Debug mode: If this option has been checked, the signal states can be
observed while the simulation is running.
External signal controls can provide filenames and paths for the program file,
for the dialog *.DLL file and for the *.WTT files. Paths which include the
current data folder (where the *.INP file is stored) or the program folder
(where the VISSIM.EXE file is stored) are saved as relative path. This way
