Field bus measurements (CAN)

The CAN-Bus is rapidly spreading through the automotive industry and in the world of automation. Thus, it is becoming vitally necessary for modern data acquisition systems to be able to capture and process field bus data in combination with analog data.

ST carries the full family of imc busDAQ/busLOG measurement equipment (options and characteristics listed below). It is a robust system architecture operated by the imc user interface software imcDevices. This MS-Windows software comes standard and enables quick and reliable measurement operation without the need for any programming. imcDevices allows measurement parameters, real-time functions, trigger machines, and storage modes to be set either fully manually or automatically. Display of measurement data plots in the Curve Window, as well as report composition with the Report Generator, are integral components of imcDevices.

busDAQ/busLOG - CAN Datalogger
A busDAQ unit can be connected to any CAN-bus subscribers such as sensors, measurement amplifiers or electronic control units and supports up to 8 nodes as well as a variety of protocols such as CCP and KWP2000. Measured data transmitted via CAN-bus can be triggered, displayed and mathematically processed as desired. The protocol parameters are configured by means of the very user-friendly software imcDevices and can be saved expressed in their physical units. Some models can be connected to the LIN and ARINC busses, in addition to the CAN-bus.

Vector database linkage
In many cases, parameter settings are already available as a Vector database which can be imported by any busDAQ modules. This makes it possible to set large amounts of parameters quickly and easily. The data storage media used are either Compact Flash data carriers or IDE hard drives, having various data storage capacities depending on requirements. The standard equipped Ethernet TCP/IP interface enables easy connection to the PC or integration into decentralized measurement networks.

busDAQ – a Personal Analyzer
The most important of imcDevices’ enhancements is the DSP computation unit Online FAMOS, which enables arbitrary definition of one’s own real-time functions and makes busDAQ a Personal Analyzer. In real time, the desired format of result data are computed from the raw data and displayed. A wide range of math and statistics functions, FFT, class-counting etc. is available for the user.

busDAQ – Data Analysis
The newest version of the signal analysis software imc FAMOS offers extensive options for analysis, evaluation and documentation of measurement results. The busDAQ unit saves the data directly in imc FAMOS format.

Universal application fields
busLOG – Data Collector
This affordable module is designed with permanently configured basic functions for standard, clearly defined data logging tasks. Its low power consumption, its signal-driven Sleep Mode and its capacity for rapid resumption of measurement by means of "Wake up on CAN", in only 200 ms, destines busLOG particularly for vehicle and fleet test applications. In such settings, the module’s high degree of data integrity, its self-activation mode, and its remote monitoring capability via Internet are great assets.

busDAQ-2 – Intelligent Measurement Networks
busDAQ-2 with its two nodes and expanded functions such as online functions, WLAN, modem, Display, and direct GPS connection is the standard module for measurement networks with decentralized CAN subscribers such as sensors, control units or CANSAS measurement modules.

busDAQ-X – Multi-bus / Multi-protocol Data Logger
busDAQ-X is the universal, configurable system module which can be expanded with additional multi-bus interfaces to up to 8 nodes. With the extended functions, such as online-functions, WLAN, modem, Display, digital in- and outputs, as well as directly connectible GPS, even complex measurement networks or dive test applications are no problem.
