VEHICLE CONTROL LANGUAGE (VCL)
Curtis 1232E/34E/36E/38E and 1232SE/34SE/36SE controllers have a built-in
programmable logic controller with application-specific functions. VCL (Vehicle
Control Language) software provides a way to implement unique and complex
vehicle control functions.
VCL is a simple programming language that will feel very familiar to
anyone who has worked with BASIC, Pascal, or C. Working with VCL requires
the installation of the WinVCL program onto a PC. WinVCL will compile
VCL programs and ash download the software into the controller through the
computer’s serial port. e install process for WinVCL will also install three
important manuals on your PC: the WinVCL User’s Guide, VCL Programmer’s
Guide, and VCL Common Functions Manual. ese manuals, which are in PDF
format, include more detailed information about VCL than is included here.
is section of the manual summarizes VCL and also describes aspects
and functions of VCL that are specic to these E and SE controllers. For a
more complete understanding of the functions and capabilities of VCL, see
the WinVCL User’s Guide, VCL Programmer’s Guide, and VCL Common
Functions Manual.
