CANbus
CANbus
A controller-area network (CAN or CAN-bus) is a serial communications bus standard, allowing electronic control modules to communicate with each other within a vehicle. It was originally designed by Bosch specifically for automotive applications. CANopen is an international standard, and is a higher-layer CAN protocol for embedded control systems. CANopen has become the standard communication bus for most electric vehicle applications including forklift trucks and other materials handling vehicles. SAE J1939 is an alternate higher-level protocol that is commonly used for IC engine-powered vehicle applications, such as agricultural vehicles, construction vehicles, and automobiles. Most recent Curtis controllers adhere to the CANopen protocol and support the DS401 IO-device profile standard. Earlier Curtis CAN controllers adhere to the CAN2.0B standard, but run proprietary higher-level protocols called Curtis Nodes 1.0 and Curtis Nodes 2.0. Please note that SAE J1939-compliant variants of certain Curtis products are possible -please contact us for more information.
VCL®
VCL®
Curtis VCL -Vehicle Control Language - is an easy to use software programming language that allows vehicle developers to create customized functionality within the Curtis controller. It includes CAN communications control, I/O configuration and mapping, feedback-loop process blocks such as Proportional-Integrator -Differentiator (PID), and many other powerful functions. A comprehensive library of VCL functions allows the rapid development of unique functions and combinational or sequential logic. For multi-controller, CANbus applications, VCL enables the developer to configure the network and fully utilise all of the I/O available. VCL also allows the easy integration of Instrumentation and other 3rd party devices, and eliminates the need for expensive dedicated vehicle system controllers. Depending on the customer's preferences, Curtis offers customers VCL training, or we can provide a VCL development service, where Curtis engineers will work together with OEM engineers to create the custom VCL code required for each project.
Real-Time-Clock
Real-Time-Clock
The built-in capability to measure date and time-of-day allows the user the flexibility to set parameters in VCL® to capture specific operational information. Instances are recorded and time/date-stamped according to the time of occurrence. This may include any pre-programmed parameters such as fault diagnostics, operational information and threshold exceptions.

Instruments

CAN and Serial Communication instruments from Curtis display vehicle data and fault information. These gauges connect directly to Curtis controllers and I/O modules, easily, seamlessly and conveniently. The communication protocol enables lower vehicle cost by minimizing wiring between system components. Additional I/O in the gauges allow system inputs (switches, sensors, throttles, etc.) near the operator to be transmitted to the controller via the communication link in the gauge. Curtis gauges and instruments can be used to program or configure vehicle settings. Curtis instrumentation is designed to be easy to read, with large displays, and sealed to meet the toughest environmental conditions.
