CAN Bus Module

May 1, 2004
As an addition to the vendor’s WE7000 PC-based data acquisition platform, the WE7081 Controller Area Network (CAN) bus module is a bi-directional module that adds a new dimension of measurement capabilities.

The WE7081 CAN module is used to interpret the CAN protocol and hence measure the measured CAN “payload.” Through a flexible software control panel, the module hardware settings can be reconfigured to support any CAN configuration, including baud rate and frame structure. While each module supports up to 64 CAN channels, the module/station architecture supports scalability to hundreds or thousands of channels. The WE7081 includes the ability to synchronize automatically with other measurement modules, so that CAN sensor data (such as ABS, EDU or transmission) can be correlated directly with voltage or timing signals (such as throttle position, RPM or temperature). The assorted module binding ability of the WE7000 station means that any two measurement modules can share timing information across the backplane.
