Powerful Data Acquisition & Control Software for Powertrain Testing

The iTest system is the central control system in a modern Powertrain test cell. In this function it executes a predefined test schedule by coordinating the dynamometer and throttle systems, along with data acquisition from sensors on the test article or in-cell instruments. iTest achieves this level of functionality through an intuitive configuration editor and user-friendly operator GUI, while employing international standards for connectivity to the test cell instruments. The operator can select from a library of test cycles based on testing standards from North American, European or Asian governing organizations.

Features

• PC-based system that supports a wide range of applications, from durability to performance and R&D
• Convenient off-line simulation for test developers
• Pre-configured instrument and test cycle modules for easy and flexible test building
• 150+ existing interfaces to common-third party measurement instruments
• Powerful display builder and configuration utilities
• iView Web Server for convenient remote monitoring
• Reporting package provides reports at the test cell 

iTest GUI

The Automation Console software provides a powerful graphical user interface (GUI) that runs in a Windows environment. The GUI provides access to the screen definition tools both in the test building environment and during run time.

Features User friendly interface Powerful display builder in both development and runtime modules Graphical display of test data Push buttons and slider controls for manual operation Error and message windows

Test Manager

The Test Manager provides a powerful environment for developing test configurations that will guide the test during runtime. In designing a test, development engineers have a variety of options, from simply selecting from a list of pre-defined modules corresponding to the in-cell instruments, to writing script-driven routines.

A&D has developed a modular system for adding test cell instruments or test cycles to a base application. Modules contain command sets specific to the instruments in use, with common commands used by a common test. This allows a single test to be used with a variety of instrument modules in different test cells, streamlining the test development process.

Test Modules

iTest Application Modules are designed to integrate a wide variety of thrid-party devices and tests into a test cell.   They contain the necessary application code to remotely control these devices. 

Device Modules	Driver Modules	Test Modules

Runtime Software

The iTest system provides a fast, reliable environment for controlling the dynamometer and throttle settings in a coordinated manner. The runtime system will monitor defined parameter limits and coordinate a variety of actions on test cell instruments. All test data is available in a standard Windows format.

• User-friendly interface
• Flexible data acquisition and control for I/O systems and measurement instruments
• Monitoring of real-time limits
• Powerful diagnostic utilities
• Connection to DAC Web Server utility
